Abstract:
The increase of the number of forklifts is associated with the elevated threat of accidents and dangerous situations that should be systematically analyzed. On the occasion of the assessment, it is worth using accident ratios for given devices and dangerous situations. The article presents the results of research into the causes and effects of accidents at work of forklift trucks’ operators in 2011÷2017. The most serious accident occurred in the case of: loss of stability of the forklift truck at the bend, crush caused by the truck, impact by the truck’s load, impact by the truck itself. Most injuries arose in the case of: overturning when reversing the truck, overrunning employees’ leg, crush by the truck or its load, impact by the truck. The safety of work of the forklift trucks operators under full supervision has improved. Errors in the operation of trucks increased, which requires more frequent verification of operators' skills and the increase of their awareness of hazards.

Abstract:
Accidents with mining dump trucks are still common, especially those with small vehicles located in mining locations. The limited visibility of the driver of the large dump truck to see small vehicles around it cause these accidents. This paper presents a small vehicle detection system prototype designed to improve the visibility of the dump truck’s driver. This system works by initially a dump truck detecting the 433 MHz radio frequency, which indicates the small vehicle is around the dump truck. A buzzer sound, controlled by Fuzzy logic according to the distance of small vehicles, also equips the system. It then triggers the truck’s ultrasonic radar to sense the position of small vehicles. The warning information will be displayed on the 16 x 2 LCD. At the same time, a TFT LCD presents the angle and distance of small vehicles. With this system, a dump truck's driver can realize the presence of small vehicles earlier and detect the position and distance of those vehicles.

Abstract:
This paper presents control algorithms enabling autonomous heterogeneous trucks to drive in platoons. Heterogeneous trucks imply that the hardware information (e.g., truck length, break, accelerator, or engine) of a truck may be distinct from that of another truck. A platoon is defined as a collection of trucks where a manually driven truck (leader truck) is followed by several automatically controlled following trucks. This paper is novel in presenting the longitudinal control of a truck platoon, as the trucks move along a curved lane as well as a straight lane. For a lateral maneuver, this paper proposes making every autonomous truck keep following the leader’s waypoints while maintaining a designated distance from its predecessor truck. This paper develops both a lateral maneuver and speed control considering a platoon of heterogeneous trucks. The efficiency of the proposed approach is verified using simulations.

Abstract:
Purpose – The purpose of this paper is to propose a model that determines the strategy of owning and renting trucks in combinations with internal truck scheduling and storage allocation problems in container terminals. Design/methodology/approach – To deal with this complicated problem, a two-level heuristic approach is developed, in which the integration problem is decomposed into two levels. The first level determines the daily operations of the internal trucks, while the second level determines the truck employment strategy based on the calculation in the first level. Findings – The results show that: even if the using cost of owned yard trucks is much lower than the cost of rented yard tucks, terminal companies should not purchase too many trucks when the purchasing price is high. In addition, the empirical truck employment strategies, which are purchasing all the trucks or renting all the trucks, are not cost-effective when compared with the proposed yard truck employment strategy. Originality/value – The paper provides a novel insight for the internal truck employment strategy in container terminals which is the determination of the strategy of employing renting and outsourcing yard trucks to meet operational daily transportation requirements and minimize the long-term cost of employing yard trucks. A mathematical model is proposed to deal with the practical problem. Also, this study presents better solution than empirical method for employing different types of yard truck. Thus, in order to obtain more benefit, terminal companies should employ the proposed yard truck employment strategy.

Abstract:
The study is dedicated to increasing open pit trucks with electrical transmission maneuverability indices. The possibility of forced controllability usage of rear traction wheels of open pit truck with the electrical transmission, which enables them to carry out maneuvers with the usage of a forced additional turn is presented. For the first time, there has been worked out a mathematical model of the forced additional turn. It enables to determine a correlation of rotational speed ratio of rear traction wheels of starboard and port sides of the wheeled vehicle relative to a tire-to-surface friction coefficient. Firstly, the analytical dependences, which allow predicting the indices of open pit trucks maneuverability while using the forced additional turn are determined. The mathematical model adopted to appropriate truck's electric drive control algorithm can lead to trucks performance increasing by means of maneuvering time reducing.

Abstract:
The overhead catenary truck is an interesting technology for long-haul transportation with heavy-duty trucks because it can combine the advantage of energy supply via catenary while driving and the flexibility of a battery truck on routes without catenary using the traction battery. This study investigates the energy consumptions of overhead catenary trucks on German highways and considers different configurations for the traction battery and catenary power system. Afterwards the life cycle costs of overhead catenary trucks are calculated for a specified long-haul transportation scenario and the results are compared to battery electric truck and diesel truck using the findings of a previous study by the authors. The energy consumption of the considered overhead catenary trucks is approximately equal to that of a battery electric truck but only about a half of the equivalent energy consumption of a conventional diesel truck. According to the cost assumptions in this study, the total life cycle costs of overhead catenary trucks can be in the range of the conventional diesel truck, showing the competitiveness of this alternative truck technology.

Abstract:
Autonomous vehicles have become important with the emergence of Logistics 4.0. Moreover, truck-based transport has become the critical means of transport in the logistics market. Thus, to deal with the pending issues of the logistics market, it is not enough to merely expand the workforce. Adopting autonomous trucks will also help change the truck allocation structure. This may enable horizontal and vertical integration based on the new logistics model and help address various problems faced by shipping companies. Thus, adopting autonomous trucks can provide various benefits for the logistics business, society, and consumers. However, adopting autonomous trucks does not only have benefits. Here, this study suggests truck platooning as a method of adopting autonomous trucks more efficiently. Furthermore, we approach the potential issues regarding autonomous truck adoption from various perspectives by demonstrating the efficiency of autonomous trucks as well as their problems.

Abstract:
The construction of intelligent logistics by intelligent wireless sensing is a modern trend. Hence, this study uses the multistate flow network (MFN) to explore the actual environment of logistics delivery and to consider the different types of transportation routes available for logistics trucks in today’s practical environment, which have been neglected in previous studies. Two road types, namely highways and slow roads, with different speed limits are explored. The speed of the truck is fast on the highway, so the completion time of the single delivery is, of course, fast. However, it is also because of its high speed that it is subject to many other conditions. For example, if the turning angle of the truck is too large, there will be a risk of the truck overturning, which is a quite serious and important problem that must be included as a constraint. Moreover, highways limit the weight of trucks, so this limit is also included as a constraint. On the other hand, if the truck is driving on a slow road, where its speed is much slower than that of a highway, it is not limited by the turning angle. Nevertheless, regarding the weight capacity of trucks, although the same type of trucks running on slow roads can carry a weight capacity that is higher than the load weight limit of driving on the highway, slow roads also have a load weight limit. In addition to a truck’s aforementioned turning angle and load weight capacity, in today’s logistics delivery, time efficiency is extremely important, so the delivery completion time is also included as a constraint. Therefore, this study uses the improved d-MP method to study the reliability of logistics delivery in trucks driving on two types of roads under constraints to help enhance the construction of intelligent logistics with intelligent wireless sensing. An illustrative example in an actual environment is introduced.

Abstract:
The evolution of traffic-related accidents caused by long, short, and medium trucks at signalized road intersections have been underemphasized in the last few years. Far, little attention has been paid to the modelling of trucks traffic flow using an artificial neural network model and evaluating the stability analysis of trucks depending on the heterogenous optimal velocity. This research evaluates the effect of trucks on some specific traffic flow features. Over the years, it has been deduced that trucks, irrespective of their sizes, significantly impact their surrounding traffic flow due to their body sizes and operational features. In this study, we focused on modelling the traffic flow of trucks at signalized road intersections using traffic flow variables such as speed, traffic volume, traffic density, and time as our inputs and outputs. The truck traffic data was collected using up-to-date equipment such as video cameras and inductive loop detectors from the South Africa transportation network. During the ANN modelling of the truck traffic flow, we used 956 traffic datasets divided into 70% for training and 15% each for testing and validation. The ANN model results show testing regression values of R2 (0.99901). This shows that the inputs and output are well correlated and the ANN model’s superiority in predicting truck traffic flow at signalized road intersections. Based on the HEOV model results, the result of the research indicates that in the mixed traffic flow of trucks in real-life scenarios, the proportion of different trucks on the signalized road intersections rather than the proportions of types of trucks can be used in the determination of traffic flow stability of each truck. This research extends our knowledge of truck traffic flow modelling and provides a blueprint for examining the stability analysis of long, short, and medium trucks in their immediate driving environment.

Abstract:
A method is proposed to predict the handling and roll properties of electric drive mining trucks and evaluate their safety status. Trucksim is used to simulate the truck dynamics and Simulink is used to model the electric drive system, the truck model takes a double-lane change manoeuvre according to ISO 3888-1. A 190t mining truck is demonstrated and the understeer gradient and roll angle results respect its safety status well. Using this method, mining truck designers could make the handling and roll prediction before manufacture and modify their design.

Abstract:
Gourmet food trucks have emerged as increasingly popular dining alternatives for consumers in today's urban landscape. Existing literature, as well as my own ethnographic research within Orlando, Florida's mobile food vending scene, reveals that food truck owner/operators utilize various strategies to establish a viable niche for themselves in this diversified and burgeoning market. Among other things, these strategies include online social networking, creating and maintaining a recognizable brand identity, collaborating with local retailers and bar owners, and incorporating organic and locally produced ingredients in their dishes whenever possible. As in other parts of the country, there appears to be a growing concern in greater Orlando about local diets and the profound and subtle messages it conveys about contemporary eating habits. I contend that dining at gourmet food trucks represents a legitimate declaration of consumer identity about individual beliefs and values. In my thesis, I examine how Orlando's gourmet food trucks offer consumers a greater selection of food options and allow locals to participate in a viable social network and community.

Abstract:
The biggest shift in the automotive industry lies ahead. Autonomous vehicles create both curiosity and skepticism among drivers and people around. Autonomous vehicles, more specifically trucks, will not be utterly self-driving overnight. The whole transformation will take place in different phases. When a vehicle does not need a driver behind the wheel, new needs will arise. This is where this project comes into play. On behalf of Scania, a new driver’s seat shall be developed for new needs from the drivers for autonomous trucks of type 4. The project was carried out at Scania’s design department for cabin interiors. The project aimed to develop new needs for the future autonomous level 4 trucks in order to develop a driver’s seat that meets these needs. The project began with a planning phase in which the goals and the time frame for the project were set up. The project was then implemented in four different phases inspired by CDIO (n.d.). The work began with a benchmarking on existing trucks and passenger cars, but also on the future visions of different competitors regarding autonomous vehicles. Much work was put into understanding theories and interpreting relevant information. The users were used early in the project in the form of interviews, observations, and a survey that reached 299 truck drivers. The work then continued with various forms of brainstorming both within the project group and together with engineers from the group at Scania. The final work contained a CAD model of both prototype, CAID models of the final design, and a prototype scale of 1:1. The final result of the project is a new driver’s seat with the possibility of pushing the seat almost three times further back than the current seat. It can now be done when the driver’s seat is part of the bed. During the user study and the brainstorming, new needs were taken from the perspective of the sun being able to adapt to three different positions; rest, drive, work. The new driver’s seat now gives the drivers this opportunity. The result of this project may be more effective in driving the driver, which benefits both Scania and the customers in the form of the drivers being able to drive longer than previously allowed.
Det största skiften inom fordonsbranschen ligger framför oss. Autonoma fordon skapar både nyfikenhet och en skepsis bland förare och människor runt omkring. Autonoma fordon, mer specifikt lastbilar, kommer inte bli helt självkörande under en natt. Hela för- vandlingen kommer ske i olika faser. När ett fordon inte behöver en förare bakom ratten kommer nya behov uppkomma. Det är här det här projektet kommer in i bilden. På uppdrag av Scania, ska en ny förarstol utvecklas för nya behov från förarna för autonoma lastbilar av typen nivå 4. Projektet är ett examensarbete gjort av två studenter vid utbildningen civilingenjör inom teknisk design med inriktning produktutveckling, vid Luleå tekniska universitet. Projektet genomfördes på Scanias konstruktionsavdelning för hyttint- eriör. Målet för projektet var att ta fram nya behov för framtidens autonoma nivå 4 lastbilar för att sedan utveckla en förarstol som uppfyller dessa behov. Projektet började med en planeringsfas där målen och tidsramen för projektet sattes upp. Projektet genomfördes sedan i fyra olika faser inspirerade av CDIO (n.d.). Arbetet började med att en benchmarking gjordes på befintliga lastbilar och personbilar men även på olika konkurrenters framtidsvisioner gällande autonoma fordon. Mycket arbete lades på att förstå teorier och tolka relevant infor- mation. Användarna användes tidigt i projektet i form av intervjuer, observationer och en enkät som nådde ut till 299 lastbilsförare. Arbetet fortsatte sedan med olika former av brainstorming både inom projektgruppen och tillsammans med ingenjörer från gruppen på Scania. Slutgiltiga arbetet innehöll CAD-modeller av både prototyp, CAID-modeller av slutgiltig design samt en prototyp i skala 1:1. Det slutgiltiga resultatet av projektet är en ny förarstol med möjligheten att skjuta bak stolen nästan tre gånger längre än vad som tidigare var möjligt. Det kan nu göras då förarstolen är en del av sängen. Under användarstudien och brainstormingen togs nya behov fram i from av att solen ska ha möjlighet att anpassas till tre olika lägen; vila, köra, arbeta. Den nya förarstolen ger nu förarna den här möjligheten. Resultatet av det här projektet kan komma att effektivisera föraryrket, vilket gynnar både Scania och kunderna i form av att förarna kommer kunna köra längre än vad tidigare varit tillåtet.

Abstract:
An experimental investigation was conducted aimed at reducing fatalities and injury associated with head-on collisions between passenger vehicles and trucks, or other heavy vehicles. Such collisions create extensive and hazardous damage to the car and relatively little to the truck. This disparity is brought about in part by the difference in heights between the truck's and car's bumper, which permits the truck to override the front structure of the car leading to extreme occupant compartment intrusion, and in part by the much greater strength of the truck's structure. This work focuses on the design, testing and development of a mechanism, mounted to the front of a truck, to prevent underride and to absorb a significant portion of the crash energy. It is important to note that not all the objectives were required to be met in any one test. Each experiment was an integral contribution to a final practical solution. Seven full-scale car-to-truck crash tests were performed using a prototype bumper bar system at impact speeds ranging from 56 to 100 km/h. This bumper bar system consists of a rigid barrier supported in front of the truck by four telescopic struts incorporating ball joints at each end, making the assembly a ball jointed spatial mechanism. The use of a mechanism largely eliminates bending moments within the supporting struts, which if resisted, would require very large and heavy components. Energy absorption is via the plastic deformation of thin wall seamless steel tubing undergoing the inversion mode of collapse. The properties of the steel tubes were determined from quasi-static conditions, low speed dynamic tests ranging up to 30 km/h and one high speed test at 80 km/h. No strain rate sensitivity was detected in these tests. The results were therefore used to estimate the energy absorbed by the truck bumper bar system in the crash test collisions. From these initial car-to-truck collisions it was concluded that it is possible to significantly reduce the severity of head-on collisions between cars and trucks at very hazardous closing speeds with suitable energy absorbing, underride resisting truck bumper bars. Further work is needed to examine a wider range of collision modes and to develop means of reducing the bulk of the truck bumper bar components.

Abstract:

Title: Volvo Trucks' Customer Value Proposition

Authors: Ekaterina Storubleva, Gregor Milosch, Christian Neumann

Tutor: Erik Hunter

Date: May 2009

Keywords:

Volvo Truck Corporation, truck industry, customer value, value drivers, retail strategy, communication, relationship marketing

Purpose:

The purpose of this thesis is to evaluate the general composition of Volvo Trucks' customer value proposition in Europe and to examine possible ways of enhancing it using Volvo's retailing strategy as a tool.

Background:

The concept of customer value gains more and more importance in modern companies. Firms have to truly understand what their customers expect in order to provide the right products for them.Truck manufacturing is a very cyclical industry, which is why in times of crisis, when trade volumes go down, they need to excel even more in order to maintain good business relations with their customers. Volvo Trucks, one of the world's leading truck producers, has adopted a special retailing strategy, in which it owns strategically important dealerships, in order to improve customer understanding and consequently customer value. This paper discusses in how far they succeed at this.

Method:

The authors followed a triangular approach, combining quantitative and qualitative research. The quantitative part was covered by a communication chain study and a value driver study, both developed by the authors. In the qualitative part, each participant answered ten open questions, which were then used for internal consistency checks and contributed additional thoughts.

Conclusion:

The Volvo Truck Corporation (VTC), by adapting its retail strategy, realized the importance of establishing long-term customer relationships and generating adequate intelligence about customer needs. The company not only incorporated influential elements of relationship marketing but also strives for sustainable improvements in customer-perceived value. However, some conflicts between the stakeholder groups involved have been discovered. The corporation's core values were found to be in line with customer preferences.

In essence, it is crucial for Volvo Trucks to implement the ideas of relationship marketing, establish superior communication channels, and to promote a common understanding of customer value.

Abstract:

Modern heavy trucks tend to get more and more equipment demanding electric power. As a result, the electric power left for startingbecome more and more limited. If a complete view of the entire starting system-battery, starter and the combustion engine - is used, the total system can be investigated and optimized. This thesis is a study of the starting system and its components. Theories for each component are presented and models are derived for a complete starting system. Focus lies on the battery and starter motor. The purpose of the modelling work is to gain knowledge of the starting system. Some results can also be obtained from the simulations - it is very important to keep the electrical resistance as low as possible and the differences between battery types are surprisingly big.

Abstract:
AbstractWith the increase of stringent emission standards and higher road transportation cycles in the last few decades, the importance of transport and fuel efficiency plays a major role. The aerodynamic forces on trucks have a huge impact of the overall fuel consumption rate. For a 40 tonnes semi-trailer truck at 85 km/h on a flat highway, around 40% of the provided engine power is needed to overcome the air resistance (Hucho in Aerodynamik des Automobils. Vieweg + Teubner, Wiesbaden, [1]). An efficient way to reduce the aerodynamic drag of trucks is to build a platoon of trucks. To assess the potential of a truck platoon due to slipstream effect, computational fluid dynamic (CFD) simulations were conducted. The simulations were performed for a platoon with three trucks for different constant velocities at different inter-vehicle distances. The results are summarised in a normalised drag coefficient and fuel reduction map. As a limiting factor of platooning, the thermal management aspect must be considered, because the slipstream reduces the air mass flow through the engine compartment. This aspect of reduced air mass flow through the engine compartment was analysed as well.

Abstract:
AbstractIn order to examine equivalent axles load with dynamic load taken into account, pavement roughness test is carried out with a Vehicle Axle-tire Dynamic Load Tester, where axle-tire vertical acceleration of heavy trucks and light trucks are tested, respectively. Dynamic load is considered as a series of static loads following a normal distribution, and equivalent axles load is calculated according the Asphalt Pavement Design Specification. The results show that equivalent axles load time increase accordingly based on highway class. when tensile strain at bottom of surface is taken as design index, on high class highway equivalent standard load increases 8.3–14.9% for heavy truck, 3.6–5.4% for light truck; on low class highway, it increases 6.8–17.3% for heavy truck, 3.2–12.5% for light truck; when tensile stress at the bottom of semi-rigid base is taken as checking index. On a high class highway, it increases 34.2–64.9% for a heavy truck, 14.2–21.8% for a light truck; on a low class highway, it increases 27.5–77.1% for a heavy truck, 12.6–53.2% for a light truck. These research findings provide in-depth understanding regarding vehicle axle load conversion in dynamic load environment.

Abstract:
Abstract During natural disasters, such as hurricanes, tornadoes, earthquakes, and floods, utility trucks with boom equipment, also known as bucket trucks, are often the first responders in assisting in the rebuilding and recovery process in affected areas. Crew safety is critical while driving utility trucks in hazardous weather conditions to ensure efficient and effective service delivery to affected communities. Therefore, the utility truck’s stability while driving in extreme weather conditions is a crucial aspect of the safety of the rescue crew. This paper proposes an advanced novel method to investigate and manage the stability of autonomous utility trucks equipped with morphing booms under crosswind. The proposed method involves developing mathematical models to analyze the truck statically, simulating various crosswind scenarios to identify the stability issues, and implementing a solution to mitigate those issues by morphing strategies. The mathematical model considers crosswind effects on the truck, including the aerodynamic forces and moments, the lateral displacement, and the roll angle. The model then simulates different crosswind scenarios (varying wind speed and direction) and evaluates the truck’s stability and performance under different weather conditions. This study offers valuable insights for improving the stability and safety of an autonomous utility truck under diverse and challenging crosswind conditions.

Abstract:
A Train Operation and Energy Simulator (TOES™) model was created in order to investigate the potential benefits of replacing three-piece trucks with the “Steered Frame Truck” currently under development. Loaded coal trains were simulated with three-piece trucks and with Steered Frame Trucks. Both trains were modeled traveling on Norfolk Southern’s Pocahontas division from MP V435 to V399. The consist and direction of travel are based on actual trains in service. It was found that the model predicts several benefits for replacing three-piece trucks with Steered Frame Trucks. These resulted from the Steered Frame Truck having a greatly reduced rolling resistance while traveling around a curve. The benefits were found to include: a significant reduction in fuel consumption, a reduction in in-train forces, and a small increase in average velocity. One drawback was also predicted: that the reduced rolling resistance would necessitate the increased use of air brakes while traveling down-hill. Although Steered Frame Trucks should produce a considerable reduction in lateral forces, modeling such a reduction was beyond the scope of this work. Similarly, modeling other potential benefits not directly derived from the Steered Frame Truck’s reduced rolling resistance was not considered here.

Abstract:
Sri Lanka depends heavily on road for freight transportation where around 97% of domestic freight is transported by roads using trucks [1]. It was further related that half of the above trucks returning empty [1]. Such empty truck return runs go unnoticed in Sri Lanka. In other developed countries, digitalization such as digital tracking and tracing is used to minimize empty return runs of trucks by making them noticed by the parties in the supply chain. No such digital tracking and tracing is available in Sri Lanka to provide real time information on the truck operations. Therefore, the empty return runs remain unnoticed. Because of its being unnoticed, these empty space in the return runs of trucks are not used optimally. Lack of optimal use of these available space in the return runs of trucks incurs high cost of operation and lowers the net profit of truck operators. High cost and lower profit to truck operators leads to increase in charging high transportation cost from the shippers (local farmers). High transportation cost affects all the parties in the supply chain including the customers, suppliers, transport operators and the country. Therefore, the objective of this study is to propose a digitalization approach of tracking and tracing the trucks that could give real time information on truck operations in Sri Lanka. This digitalization approach can help suppliers, transport operators and regulators to better utilize the empty space available in the return runs of trucks. This approach would pave the way for better customer satisfaction as it could reduce the freight transport costs..

Abstract:
Prototype versions of the RESCO Steered Frame Truck were operated through a section of revenue track at Louden, TN, which has been outfitted as a wayside measurement site. The site contains several different measurement stations, which record lateral forces, angles-of-attack, etc. The site routinely measures revenue trains passing along that section of track. A test car, fully loaded to 286,000 lbs and fitted with the steered trucks, was operated through the test site a substantial number of times. The results from this testing were compared with data from standard 3-piece trucks and also from premium M-976 trucks, both in revenue service trains, from the same test site. It was found that neither the premium trucks, nor the standard 3-piece trucks, showed any significant steering through the ∼5° curves at the test site. The premium trucks did show a tendency to be more ‘square’ in the curves, although there were still substantial numbers that showed significant ‘warping’ behaviour. By comparison, the steered trucks showed virtually perfect steering and alignment behaviour. This was impressive in itself but was more so when it was found, after the test was concluded, that an interference between the truck and a bracket on the car body had prevented full rotation of the steered truck throughout these tests.

Abstract:
Exposure to whole-body vibration (WBV) and the postural requirements of the job have been identified as important risk factors in the development of musculoskeletal disorders of the back among workers exposed to a vibratory environment. This paper focuses on preliminary results of WBV data collected for two groups of haulage trucks — four older trucks from manufacturer A (MFR-A) and two newer trucks from manufacturer B (MFR-B). All of the trucks and their respective seats were considered to be in good working order during the study. Measurement periods for the truck groups had similarities, but varied from 2 to 58 minutes. Sampling times for the older trucks included a mean of 19.5 minutes and a standard deviation (STD) of 6.5 minutes compared to a mean of 40.8 minutes and a STD of 12.1 minutes for the newer trucks. Data collection coincided with the approximate delivery and first operation of the new trucks, and occurred approximately 12 months apart under similar weather and road conditions, and with the same drivers except an additional driver was included with the older trucks. Truck routes were somewhat different in that quarry production had changed location in the time between data collection activities. Overall, the results suggest that the newer trucks may provide better overall isolation to drivers/operators from WBV exposure compared to the older trucks operating at the quarry; although, this will need to be confirmed with additional measurements. Considering the higher variability and shorter sampling times for the older trucks, the results should be viewed with caution. For two of seven trials, the older trucks showed that seats amplified vibration, i.e., a transmissibility (T) >1.0. Seat T for the older trucks ranged from 0.31 to 1.17 with a mean of 0.77 and STD of 0.32. This contrasted with the newer haulage trucks where seats amplified vibration in 3 of 8 trials. In this case, T did not vary greatly and ranged from 0.87 to 1.05 with a mean of 0.97 and STD of 0.07. Regarding older trucks, in five of seven trials, the seat (output) data of weighted root-mean square (RMS) acceleration (wRMSz) for the dominant z-axis exceeded the action level of 0.5 m/s2 action level recommended by the European Union Good Practice Guide for WBV (EUGPG) and levels exceeded the recommended exposure limit of 1.15 m/s2 in two of the seven trials. The wRMSz values for the older trucks varied from 0.41 to 1.83 m/s2 with a mean of 0.99 and STD of 0.57. Similarly, newer trucks indicated a narrower range of wRMSz from 0.38 to 0.95 m/s2. The mean wRMSz was lower for the newer trucks at 0.58 m/s2 with a STD of 0.23 m/s2. Similarly, newer trucks indicated wRMSz reached or exceeded the action level in four of eight trials. None of the trials with the new trucks showed wRMSz levels that reached or exceeded the recommended 1.15 m/s2 exposure limit. As an indicator of driver/operator discomfort, overall weighted total RMS acceleration (vector sum) values seem to show a “rougher” ride for the older trucks. The vector sum values for these trucks ranged widely from 0.70 to 2.59 m/s2 and, in four of seven trials, showed levels greater than 1.40 m/s2. The mean vector sum was 1.44 m/s2 with a STD of 0.75 m/s2. Comparatively, the newer trucks exhibited less variation with a range from 0.69 to 1.59 m/s2. The mean vector sum was 1.02 m/s2 with a STD of 0.35 m/s2. Vibration dose values for the dominant z-axis (VDVz), gave a sense of vehicle jarring/jolting conditions. All trials with the older trucks were within the recommended EUGPG action level of 9.1 m/s1.75. On the other hand, in three of eight trials, both newer trucks exceeded this action level with values of 9.18, 12.58, and 13.21 m/s1.75. Neither truck group showed VDVz that exceeded the exposure limit of 21 m/s1.75. A statistical analysis was not conducted, since the differences reported between truck groups may not be statistically significant owing to the relatively small sample size. Road conditions, changes in the truck routes, and driver/operator differences (e.g., stopping and turning) are possible factors in the higher VDV for the newer trucks.

Abstract:
Abstract This paper describes an investigation into the causes of cracking of transit car truck side frames on the PATCO system. The investigation included inspection of the PATCO fleet, laboratory examination of a sample from a failed truck, field-testing of an instrumented truck, measurement of residual stresses in the truck, and engineering analysis of the resulting data. It was concluded that the observed cracks were slowly propagating due to fatigue from low-level stresses induced by lateral and vertical loading from routine curving forces and other vehicle-track interactions. The side frames with fatigue cracks can be repaired by welding without the need for postweld stress relief and the lifetime of those that do not have cracks at present can be extended by preventive measures. The combination of preventive measures and repairs should enable the trucks to serve for the balance of the PATCO fleet lifetime without the need to purchase replacement trucks. Continued surveillance of the trucks in the area of concern will be necessary.

Full text
Abstract:
The primary purpose of this study is to provide a qualitative analysis of the dynamics of the self-steering trucks that are commonly used for freight locomotives on improving curving performance and increasing adhesion in curves. Although there are a number of anecdotal statements on the ability of steerable trucks to reduce curving forces and increase adhesion in curves, to the best of our knowledge, there exists no study that provides a qualitative or quantitative analysis of these features of steerable trucks. Two aspects of locomotive trucks are essential for their ability to deliver small curving forces and high adhesion in curves. First, the ability to allow the axles to yaw sufficiently relative to the truck frames, such that they can hold a small angle of attack with the rail. Second, to provide sufficiently large longitudinal stiffness between the end axles and the axles and truck frame, in order to accommodate high adhesions. An equivalent stiffness analysis is used to show that the two steerable trucks that are considered for this study are far superior to conventional, three-axle, straight trucks in providing both a smaller angle of attack and a higher longitudinal stiffness for better curving and adhesion characteristics. The qualitative analysis of this study agrees with the experience the railroads have had with their self-steering trucks. The findings of this study indicate that self-steering trucks can result in lower lateral forces, accommodate tighter curves, and deliver higher adhesion in curves; without lowering the critical hunting speed of the locomotive. The results further show that the steering mechanism stiffness can have a large effect on the lateral, longitudinal, and yaw stiffness between the end axles; therefore, significantly lowering curving forces, and increasing adhesion and critical hunting speed of the truck.

<div class="section abstract"><div class="htmlview paragraph">The objective of the project was to compare the fuel consumption of a prototype hybrid electric CNG truck with that of two trucks: a CNG truck and a diesel truck for the similar market and operating conditions. The tests were conducted on a test route representative of the conditions encountered by these vehicles in normal driving operations. The test route length was 276 km with a maximum altitude difference of 374 m. The test route had four sections, including a hilly section with a length of 88 km. The result of the comparison between the two CNG trucks was expressed as fuel savings of CNG in percentage. The fuel consumption of the diesel truck was accurately measured using the gravimetric method. The hybrid electric CNG truck showed average fuel savings of 3.6% and demonstrated up to 7.7% in savings for the entire trip compared to the CNG truck. On the hilly section of the route, the hybrid electric CNG truck showed average fuel savings of 22% for the ascending portion and 9.7% for the complete section. On this section, the hybrid electric CNG truck also demonstrated superior dynamic behavior compared to the other two trucks. The torque and power contribution of the electric axle led to a less demanding and more economical behavior for the hybrid electric truck engine on the ascending section of the hilly route. The hybrid electric truck took a shorter time to complete the hilly section of the route compared to the other two trucks.</div></div>

Abstract:
Road safety is influenced by the dynamic performance of heavy trucks during emergency maneuvers that involve abrupt changes in direction and velocity. In this context, rating of trucks performance under such situations becomes crucial to promote safer roads. Present test methods to evaluate trucks performance during braking and lane change maneuvers involve substantial monetary and time investments, and are limited to certain critical trucks and cargo. A more general methodology to evaluate a wider range of vehicles under diverse situations is thus necessary. In this paper the conceptual design of a truck testing facility is proposed to characterize and compare the dynamic performance of the vehicles under emergency maneuvering, as a function of the components’ properties, payload conditions and overall truck design. The equipment consists of a moving platform on which the vehicle is mounted, including load cells to measure tire loads. The motion of the platform can simulate steering maneuvers by providing lateral and yaw excitations.

Full text
Abstract:
Inside frame trucks were historically unacceptable on freight cars, because of bearing maintenance problems which the modern roller bearing eliminated. This paper is a design study showing the potential advantages of a modern inside frame truck particularly in improvements in reducing weight and maintenance requirements, and was inspired by a short wheelbase inside bearing four wheel truck that the auhor designed to replace the original single axle trucks on an updated version of the Iron Highway articulated integral train. The new truck had to be interchangeable with the original without frame or car structure: a four wheel truck in a two wheel space! The design was completed, operation simulated, and a truck built, but the development stopped, for economic reasons, prior to equipping a demonstration train. This effort, though, suggested that an AAR compatible version of that truck might be advantageous, and this paper outlines how and why such a truck might be built. The paper is divided into six sections: 1) Background in the Iron Highway; 2) Requirement dictating conversion to a 4 wheel truck; 3) Design of a 286,000lb. GRL North American freight truck; 4) Maintenance considerations; 5) Economic Considerations; and 6) an Annex describing testing by the Pennsylvania Railroad of Timken inside frame roller bearing trucks 80 years ago.

Full text
Abstract:
Truck platoons have many benefits over traditional truck mobility. Truck platoons have the potential to improve safety and reduce fuel consumption between 5% and 15%, based on platoon configuration. In Illinois, trucks carry more than 50% of freight tonnage and constitute 25% of the traffic on interstates. Therefore, expected fuel savings would be significant for trucks. Deployment of truck platoons within interstate highways may have a direct effect on flexible pavement performance, as the time between consecutive axle loads (i.e., resting time) is expected to decrease significantly. Moreover, platoons could potentially accelerate pavement damage accumulation due to trucks’ channelized position, decreasing pavement service life and increasing maintenance and rehabilitation costs. The main objective of this project was to quantify the effects of truck platoons on pavements and to provide guidelines to control corresponding potential pavement damage. Finite-element models were utilized to quantify the impact of rest period on pavement damage. Recovered and accumulated strains were predicted by fitting exponential functions to the calculated strain profiles. The results suggested that strain accumulation was negligible at a truck spacing greater that 10 ft. A new methodology to control pavement damage due to truck platoons was introduced. The method optimizes trucks’ lateral positions on the pavements, and an increase in pavement service life could be achieved if all platoons follow this optimization method. Life cycle assessment and life cycle cost analysis were conducted for fully autonomous, human-driven, and mixed-traffic regimes. For example, for an analysis period of 45 years, channelized truck platoons could save life cycle costs and environmental impacts by 28% and 21% compared with human-driven trucks, respectively. Furthermore, optimum truck platoon configuration could reduce life cycle costs and environmental impacts by 48% and 36%, respectively, compared with human-driven trucks. In contrast, channelized traffic could increase pavement roughness, increasing fuel consumption by 15%, even though platooning vehicles still benefit from reduction in air drag forces. Given that truck platoons are expected to be connected only in the first phase, no actions are required by the agency. However, in the second phase when truck platoons are also expected to be autonomous, a protocol for driving trends should be established per the recommendation of this study.

Abstract:
Hilly terrain poses challenges to truck platoons using fixed set speed cruise control. Driving the front truck efficiently on hilly terrain improves both trucks fuel economies and improves gap maintenance between the trucks. An experimentally-validated simulation model was used to show fuel savings for the platoon of 12.3% when the front truck uses long horizon predictive cruise control (LH-PCC), 8.7% when the front truck uses flexible set speed cruise control, and only 1.2% when the front truck uses fixed set speed cruise control. Purdue, Peloton, and Cummins have jointly configured two Peterbilt 579 trucks for relevant combinations of: (1) coordinated shifting, (2) constant or variable platoon gap controls, (3) flexible or constant speed setpoint cruise control of the front trucks, and (4) long-horizon predictive cruise control (LHPCC) of the front truck. Confirmation of this functionality during platooning was demonstrated at the Continental Test track in Uvalde, Texas. In Indiana, on-road experiments were limited to single truck operation with long-horizon predictive cruise control, flexible set speed cruise control, and constant setpoint cruise control. Data from all of the above was used to improve the fidelity of simulations used to arrive at the fuel savings and gap control findings for hilly terrain per what is summarized in the findings section. Additionally, in early summer 2020, Purdue submitted to, and received improvement from, INDOT for a safe truck platoon testing protocol (located in this report’s appendix), which could not be implemented in Indiana before the end of the project because of COVID-19. Presentations of the subject matter at COMVEC, MAASTO, Purdue Road School, and the Work Truck Show are listed in the appendix.

Full text
Abstract:
Nearly 499,000 motor vehicle crashes involving trucks were reported across the United States in 2018, out of which 22% resulted in fatalities and injuries. Given the growing economy and demand for trucking in the future, it is crucial to identify the risk factors to understand where, when, and why the likelihood of getting involved in a severe or moderate injury crash with a truck is higher. This research, therefore, focuses on capturing and exploring risk factors associated with surrounding land use and demographic characteristics in addition to crash, driver, and on-network characteristics by modeling injury severity of crashes involving trucks. Crash data for Mecklenburg County in North Carolina from 2013 to 2017 was used to develop partial proportionality odds model and identify risk factors influencing injury severity of crashes involving trucks. The findings from this research indicate that dark lighting condition, inclement weather condition, the presence of double yellow or no-passing zone, road sections with speed limit >40 mph and curves, and driver fatigue, impairment, and inattention have a significant influence on injury severity of crashes involving trucks. These outcomes indicate the need for effective geometric design and improved visibility to reduce the injury severity of crashes involving trucks. The likelihood of getting involved in a crash with a truck is also high in areas with high employment, government, light commercial, and light industrial land uses. The findings can be used to proactively plan and prioritize the allocation of resources to improve safety of transportation system users in these areas.

Abstract:
Fuel-consumption reduction in the truck industry is significantly beneficial to both energy economy and the environment. Although estimation of drag forces is required to quantify fuel consumption of trucks, computational fluid dynamics (CFD) to meet this need is expensive. Data-driven surrogate models are developed to mitigate this concern and are promising for capturing the dynamics of large systems such as truck platoons. In this work, we aim to develop a surrogate-based fluid dynamics model that can be used to optimize the configuration of trucks in a robust way, considering various uncertainties such as random truck geometries, variable truck speed, random wind direction, and wind magnitude. Once trained, such a surrogate-based model can be readily employed for platoon-routing problems or the study of pavement performance.

The Indiana Department of Transportation (INDOT) is responsible for timely clearance of snow on state-maintained highways in Indiana as part of its wintertime operations. For this and other maintenance purposes, the state’s subdistricts maintain 101 administrative units spread throughout the state. These units are staffed by personnel, including snow truck drivers and house snow removal trucks and other equipment. INDOT indicated a need to carry out value engineering analysis of the replacement timing of the truck fleet. To address these questions, this study carried out analysis to ascertain the appropriate truck replacement age, that is different across each of the state's three weather-based regions to minimize the truck life cycle cost. INDOT also indicated a need for research guidance in possible revisions to the administrative unit locations and optimal routes to be taken by trucks in each unit in order to reduce deadhead miles. For purposes of optimizing the truck snow routes, the study developed two alternative algorithmic approaches. The first uses mathematical programming to select work packets for trucks while ensuring that snow is cleared at all snow routes and allowing the users to identify optimal route and unit location. The second approach uses network routing concepts, such as the rural postman problem, and allows the user to change the analysis inputs, such as the number of available drivers and so on. The first approach developed using opensolver (an open source tool with excel) and the second approach coded as an electronic tool, are submitted as part of this report. Both approaches can be used by INDOT’s administrative unit managers for decision support regarding the deployment of resources for snow clearing operations and to minimize the associated costs.

Abstract:
The Indiana Department of Transportation (INDOT) started deploying queue warning trucks ahead of interstate work zones to alert motorists of queued traffic. Along with visually alerting the motorists, digital alerts were integrated with navigational applications such as Apple Maps, Waze, and the in-vehicle infotainment system of Stellantis vehicles. More than 45,000 hours of alerting was provided to motorists across various interstates in Indiana over a 26-month period. This report evaluated the impact of queue warning trucks on traffic using hard braking events and traffic speeds provided by granular connected trajectory vehicle data. Evaluation of over 370 hours of queuing with the presence of queue trucks and 52 hours of queuing without the queue trucks indicated a decrease in hard braking events by 80% when trucks were present with digital alerts. It was also observed that traffic speeds started to reduce approximately 1,500 to 2,000 ft in advance of deployed queue trucks.
