Abstract:
ISO 26262 - The Relevance and Importance of Qualitative and Quantitative Methods for Safety and Reliability Issues Regarding the Automotive IndustrySafety and reliability are key issues of today's and future automotive developments, where the involved companies have to deal with increasing functionality and complexity of software-based car functions. New functionalities cannot only be found in the area of driver assistance - most of the new car functions are and will be safety related as for example in vehicle dynamics control or active and passive safety systems. The development and integration of those functions will strengthen the need of safe processes during the system development. The new upcoming automotive standard on functional safety (ISO 26262), which is derived from the generic functional safety standard IEC 61508 to comply with the specific needs to the application sector of E/E-systems in road vehicles, will provide guidance to avoid the increasing risks from systematic faults and random hardware faults by providing feasible processes and requirements. It is evident that aspects and methods of the safety and reliability engineering are implemented and suited methods are performed in the development process at an early stage. This is one of the requirements of the new ISO 26262, which introduces a so called automotive safety lifecycle to handle all those activities that are necessary to guarantee the functional safety of automotive E/E-systems. In the following, a brief overview of the upcoming automotive standard, its new safety life cycle and the connected activities in order to ensure functional safety for safety related systems will be given. The main aim of this paper is to show the relevance and importance of one of the major tasks within the ISO 26262: the process of the hazard analysis and risk assessment as it is currently performed in the automotive industry. With the help of an example from the automotive sector, the basic steps of this method to determine the automotive safety integrity level (ASIL) are explained. Depending on the ASIL, safety requirements need to be derived as a result of the new standard regarding safety integrity attributes. Furthermore, the connection of the automotive functional safety process with methods for qualification and quantification of safety and reliability issues will be explained in this paper. The Fault Tree Analysis will be used to exemplify one of these methods which are applied subsequent to the hazard analysis and risk assessment and which make a contribution to the validation and verification of the safety process.

Abstract:
Functional safety is of the utmost importance in the development of safety-critical automotive systems, especially with the introduction of driver assist and automated driving systems. ISO 26262: Functional Safety – Road Vehicles, has been the de facto standard for functional safety in the automotive electronics domain since the release of its first edition in 2011. It is currently available in its second edition, published in December 2018. In this paper, we present an overview of the standard, which applies to all activities during the safety lifecycle of system development. In the concept phase of ISO 26262, the hazard and risk assessment process focuses on identifying possible hazards caused by malfunctioning behavior of electrical/electronic (E/E) safety-related systems and mitigating them through the identification of safety goals. The design phase includes system, hardware, and software development, with requirements developed from the safety goals. ISO 26262 also prescribes the functional safety management activities to be performed during the safety lifecycle and provides requirements for the supporting processes. In addition to presenting an overview of the standard, this paper highlights some major changes introduced in the second edition of ISO 26262.

Abstract:
Pro-active head restraint is a new automotive safety device. It can make a pre-estimation of the occurrence possibility of rear-end collision. Thus, the whiplash injury can be effectively reduced or even prevented. One of the key elements in rear-end collision avoidance system is to establish an effective safety distance mathematical model. Based on the running state of front car, the related calculation models of safety distance are established by means of dynamical and kinematical analysis of vehicle braking process and following process. Taken randomness of parameters into consideration, the fuzzy relations between these parameters should be validated by means of fuzzy theory. By using the MATLAB software, the study shows that safety distance model and the methods used to determine parameters are reasonable, and the false alarm can be effectively minimized.

Abstract:
The electric parking brake (EPB) system as the complex mechatronic system consists of the actuators that generate the clamping force necessary to hold the vehicle safe, the conventional calipers that convert clamp force into brake torque, electronic hardware with the Electronic Control Unit (ECU), cable harness and switches and especially the control software providing the functions that the driver will experience. Like most of the modern automotive components, the EPB is equipped with embedded electronic systems that include ECU, electronic sensors, signals, bus systems, and coding. Due to the complex application in electrical, electronics and programmable electronics, the need to carry out detailed safety analyses that are focused on the potential risk of malfunction is crucial for automotive systems. This paper describes a possible division of the EPB sub-functions between the supplier the wheel brakes and the supplier which supplying the ECU. Functional safety must be a guarantee with concerning the overall vehicle system. Functional safety is according to the requirements of the ISO 26262 standard and in the context of this paper relates solely to the E/E components (electrical and/or electronic) of the EPB. This paper covers the hazard analysis and risk assessment relevant to the EPB control software, and the derived allocation of ASIL risk levels to the EPB software elements of the functional architecture of the EPB.

Abstract:
In order to improve the performance of the automotive active safety system, the author proposes a distributed embedded ACCS hardware loop simulation system. The automotive adaptive cruise control system (ACCS) is a completely distributed embedded control system. The author adopts the method of hardware loop simulation, an ARM-based automotive ACCS simulation platform is designed, and the hardware structure and software design of the platform are introduced. The simulation results show that the performance of single-node and double-node responses to step change is basically the same. There is a network in the two-node control loop, the carrying capacity and communication bandwidth of the network are limited, which will inevitably cause information collision and retransmission, which will inevitably cause a delay in the information transmission process, with a delay of about 4.5 seconds. The system opens up the design idea of ACCS and also lays a foundation for future research in related directions, which has a certain enlightenment effect.

Quality, reliability, and safety of products are the most important requirement of manufacturer in order to maintain their product competitiveness in market. Customers needs related to quality product in the market therefore drive the design and process activities to a high quantity of analysis. One possibility to reduce the number of activities is to integrate FMEA (i-FMEA) to merge Design FMEA (DFMEA) and Process (PFMEA) through DAIREC methodology. In this paper, a regression analysis between critical dimensional decided during design stage and key process factor in current process control is analyzed using MINITAB software. A judgment on a new ranking has been decided based on process performance indices (Ppk) for improvement lot.

Abstract:
The successful use of fly-by-wire systems in aviation along with the positive experience of drive-by-wire systems with mechanical backup for braking and power steering have led to the development of complete drive-by-wire systems that reduce the cost of a vehicle, are lighter and provide better passive safety to the passenger. These systems have the form of a distributed, real-time embedded system. Similar architectures can be found in other safetycritical and mission-critical applications in avionics, as mentioned before, medical equipment, and the industrial sector. The advances in embedded system technology has enabled designers to implement low-cost and small form factor electronics. However shrinking CMOS technologies are facing considerable reliability problems since they become more sensitive to transient faults. This thesis investigates the application of traditional methods for the development of safety critical computer systems and their application on single-chip devices. The contributions of this work are briefly summarised as follows: • The development of a novel fault-tolerant architecture for protecting the processor core. • Methods for performing fault-injection experiments on embedded processor architectures. • Fault-models for multiple faults on digital systems with the use of statistical distributions. • An extensive study of a processor's behaviour under the presence of faults within its pipelined execution unit.

The objective of this study is to improve quality and reliability of safety-critical software in the nuclear industry. It is accomplished by focusing on the following two areas: Formulation of a standard extensive integrated software testing strategy for safety-critical software, and Development of systematic test-based statistical software reliability quantification methodologies. The first step to improving the overall performance of software is to develop a comprehensive testing strategy, the gray box testing method. It has incorporated favorable aspects of white box and black box testing techniques. The safety-critical features of the software and feasibility of the methodology are the key drivers in determining the architecture for the testing strategy. Monte Carlo technique is applied to randomly sample inputs based on the probability density function derived from the specification of the given software. Software flowpaths accessed during testing are identified and recorded. Complete nodal coverage testing is achieved by automatic coverage checking. It is guaranteed that the most popular flowpaths of the software are tested.
The second part of the methodology is the quantification of software performance. Two Bayesian based white box reliability estimation methodologies, nodal coverage- based and flowpath coverage-based, are developed. The number of detected errors and the failure-free operations, the objective and subjective knowledge of the given software, and the testing and software structure information are systematically incorporated into both reliability estimation approaches. The concept of two error groups in terms of testability is initiated to better capture reliability features of the given software. The reliability of the tested flowpaths of the software and that of the untested flowpaths can be updated at any point during testing. Overall software reliability is calculated as a weighted average of the tested and untested parts of the software, with the probability of being visited upon next execution as the weight of each part. All of the designed testing and reliability estimation strategies are successfully implemented and automated via various software tools and demonstrated on a typical safety-critical software application.

Full text
Abstract:
This thesis investigates the use of Synchronous Concurrent Algorithms (SCAs) in the development of safety related software, where a stricter adherence to mathematical correctness is required. The original model of SCAs is extended to produce abstract and concrete dynamic SCAs (dSCAs) that allow dynamic, but predictable, SCAs to be produced whose wiring maybe different at different values of a program counter. A relaxed implementation of the Generalised Railroad Crossing Problem is used to demonstrate each of the SCA models. SCAs were originally defined by Tucker and Thompson and were restricted to unit-delays between modules. Hobley investigated the introduction of non-unit delay SCAs and how non-unit delay SCAs may be represented as unit delay SCAs. Poole, Tucker and Thompson introduced the concept of hierarchies of Spatially Expanded Systems, of which SCAs are a form. All of these tools are used and expanded upon in this thesis to provide a mechanism enabling an SCA representation of an algorithm to be transformed into an SCA representation of a computing device that implements that algorithm, and to be able to demonstrate correctness. As each SCA model can be represented algebraically, this thesis provides the transformations as meta-algebras, i.e. algebras that can transfrom one algebra to another algebra.

Abstract:
Artificial system interaction with the real environment is in general based on the deployment of properly coordinated sensors and actuators, establishing between them a “dynamic control-loop”. The time to close this control-loop characterizes the functionality and applicability to critical systems in response time. In the case of digital control, the performance of the processor is directly related to response time. In this line computational demands in many Critical Embedded System (CES) industries such as avionics, space, automotive and railway have experienced an unprecedented growth as a consequence of the need to cope with more sophisticated software functionalities. The use of high-performance hardware features in CES, such as multicore architectures, to respond to those performance requirements, challenges the computation of tight WCET estimates. The source of this complexity comes from the interferences (contention) when accessing hardware resources shared across the different tasks running simultaneously. Several proposals advocate for hardware support to either eliminate or control inter-task conflicts on access to shared hardware resources (e.g. Time Division Multiple Access(TDMA) in buses, partitioning for caches), to simplify timing analysis via removing or controlling effect of contention. However, to the best of our knowledge, no current Commercially-of-the-Shelf(COTS) multicore processor provides complete isolation or full control of inter-task interference. As a consequence, the execution time of a software program may be inordinately affected by the load that its co-runners place on the hardware shared resources. This Thesis provides software methodologies to characterize and control the contention on COTS multicore processors so that they can be factored in measurement-based timing analysis. To that end, we make the following contributions. First, we perform an study of the vast state of the art on the topic and we propose a taxonomy to classify existing approaches with emphasis on their goals and assumptions. This helps better understanding the symbiosis and overlapping elements of the state-of-the-art works. Second, we propose a measurement-based methodology to derive the longest delay requests from a task can take accessing FIFO and round-robin arbitrated resources, fundamental to derive tasks’ worst-case contention effects. Third, with the goal of deriving time composable WCET estimates, we introduce signatures and templates to abstract contention caused and incurred by tasks in a multicore. Fourth, we present a methodology to derive WCET estimates during early design stages, before tasks (software units) are integrated. And fifth, we report our experience with timing analysis on two COTS ARM-based multicores.
La interacción de los sistemas artificiales con el entorno real esta generalmente basado en el uso de sensores y actuadores adecuadamente coordinados, generando entre ellos un "bucle de control dinámico". El tiempo de este bucle caracteriza cuan funcional y aplicable son para los sistemas críticos en tiempo de respuesta. En el caso de los sistemas de control digital, el rendimiento de los procesadores está directamente relacionado con el tiempo de respuesta. La demanda de computación en muchas industrias de Sistemas Críticos Empotrados (SCE), como la industria aeronáutica, aeroespacial, auto motiva y ferroviaria, han experimentado un crecimiento sin precedentes como consecuencia de tener que lidiar con funcionalidades software cada vez más sofisticadas. El uso de características hardware de alto rendimiento en SCE, como las arquitecturas multinucleo, para responder a esos requisitos de rendimiento, dificulta la computación de estimación WCET de forma ajustada. La fuente de esta complejidad viene de la interferencia (contención) cuando los recursos hardware compartidos son accedidos por diferentes tareas que se ejecutan a la vez. Existen varias propuestas para utilizar soporte hardware que elimine o controles conflictos inter-tarea cuando accedan a los recursos hardware compartidos (ej. Time Division Multiple Access(TDMA) en buses, particionado en caches), para simplificar el análisis de tiempo eliminando o controlando los efectos de la contención. Pero, en nuestro mejor saber, ningún procesador multinucleo Commercially-of-the-Shelf (COTS) aporta aislamiento completo o control total de las interferencias inter-tarea. Como consecuencia, el tiempo de ejecución de un software puede ser afectado por carga ejercida sobre los recursos hardware compartidos por las tareas competidoras. Esta tesis ofrece metodologías software para caracterizar y controlar la contención en procesadores multinucleos COTS para que puedan ser factorizados en análisis de tiempo basado en medidas. Para este fin, hemos hecho las siguientes contribuciones. Primero, realizamos un vasto estudio del estado del arte sobre el tema y proponemos una taxonomía que clasifica las propuestas existentes haciendo énfasis en sus logros y suposiciones. Esto ayudara a entender mejor la simbiosis y superposición de los elementos en los trabajos más actuales. Segundo, proponemos una metodología basada en medidas para derivar el mayor retraso que una petición de una tarea puede sufrir cuando aceden recursos arbitrados por FIFO o Round-Robin, algo fundamental para derivar el efecto de la contención en el peor caso Tercero, con el objetivo de derivar estimaciones de WCET que sean "composable" en el tiempo, introducimos las "signatures" y "templates" para abstraer la contención causada y sufrida por las tareas en un procesador multinucleo. Cuarto, presentamos una metodología para derivar estimaciones de WCET durante la Fase Temprana de Diseño, antes que las tareas (unidades de software) sean integradas. Y quinto, reportamos nuestra experiencia con el análisis de tiempo en dos multinucleo COTS basados en ARM.

Abstract:
The platform software architecture for the safety related embedded systems developed by Scania has become increasingly more complex. High complexity raises both the risk of failures and the time consumed by software developers to understand and debug the source code. This leads to increased software maintenance costs, which according to [24] can be between 60% and 75% of the total cost of software development. The purpose of this Master’s thesis is to investigate how a part of Scania’s current software architectural design can be further developed in order to decrease the complexity and the maintenance costs, without compromising with the essential functionality and performance. Another goal is to provide a solution that complies with the software safety requirements from ISO 26262, which Scania is planning to be able to fulfill in the future. To be able to compare our proposal for the software architecture with Scania’s current solution, a measurement tool has been developed. This tool measures the software quality metrics coupling and cohesion, which together with other software metrics gives an estimation of the architecture’s complexity. The verification of the software architecture with regards to ISO 26262 has been done using contract theory. The thesis work has resulted in alternative solutions for the software architectural design of the pressure sensor driver and the real-time database in one of Scania’s electronic control units. These solutions comply better with ISO 26262 and have lower complexity than Scania’s current solution in terms of coupling, cohesion and size of software components. This has been achieved by restructuring the software architecture and avoiding reuse of common software functions. The main conclusion of the thesis is that there is great potential for Scania to reduce the complexity of the platform software architecture and comply with ISO 26262.
Plattformsarkitekturen för programvaran i de säkerhetsrelaterade inbyggda system som Scania utvecklar har blivit alltmer komplex. Hög komplexitet medför ökad risk för att fel uppstår i programvaran samt att den tid som programvaruutvecklare spenderar med att förstå och debugga (avlusa) källkoden ökar. Detta leder till ökade underhållskostnader, vilket enligt [24] kan utgöra mellan 60 % och 75 % av den totala kostnaden för programvaruutveckling. Syftet med detta examensarbete är att undersöka hur en del av Scanias nuvarande arkitekturdesign kan vidareutvecklas för att minska komplexiteten, utan att kompromissa med någon grundläggande funktionalitet och prestanda. Ett annat mål är att erbjuda en lösning som uppfyller de säkerhetskrav för programvaran som ISO 26262 ställer, vilket Scania förbereder sig för att kunna uppfylla i framtiden. Ett mätverktyg har utvecklats för att kunna jämföra vår programvaruarkitekturlösning med Scanias nuvarande lösning. Detta verktyg mäter kvalitetsmåtten coupling (koppling) och cohesion (samhörighet), vilka tillsammans med andra programvarumått ger en uppskattning av komplexiteten för arkitekturen. Verifieringen av programvaruarkitekturen med avseende på kraven från ISO 26262 har utförts med hjälp av kontraktteori. Examensarbetet har resulterat i alternativa arkitekturlösningar för trycksensorernas drivrutiner samt realtidsdatabasen i en av Scanias styrenheter, där lösningarna både uppfyller kraven från ISO 26262 bättre och har lägre komplexitetän Scanias nuvarande lösning. Detta har uppnåtts genom en omstrukturering av programvaruarkitekturen samt genom att undvika att återanvända gemensamma programvarufunktioner. Huvudslutsatsen som kan dras från examensarbetet är att det finns stor potential för Scania att kunna reducera programvaruarkitekturens komplexitet, samt uppfylla kraven från ISO 26262.

Abstract:
The complexity of modern safety critical systems is becoming higher with technology level growth. Nowadays the most important and vital systems of automotive, aerospace, nuclear industries count millions of lines of software code and tens of thousands of hardware components and sensors. All of these constituents operate in integrated environment interacting with each other — this leads to enormous calculation task when testing and safety assessment are performed. There are several formal methods that are used to assess reliability and safety of NPP I&C (Nuclear Power Plant Instrumentation and Control) systems. Most of them require significant involvement of experts and confidence in their experience which vastly affects trustworthiness of assessment results. The goal of our research is to improve the quality of safety and reliability assessment as result of experts involvement mitigation by process automation. We propose usage of automated FMEDA (Failure Modes, Effects and Diagnostic Analysis) and FIT (Fault Insertion Testing) combination extended whith multiple faults approach as well as special methods for quantitative assessment of experts involvement level and their decisions uncertainty. These methods allow to perform safety and reliability assessment without specifying the degree of confidence in experts. Traditional FMEDA approach has several bottlenecks like the need of manual processing of huge number of technical documents (system specification, datasheets etc.), manual assignment of failure modes and effects based on personal experience. Human factor is another source of uncertainty. Such things like tiredness, emotional disorders, distraction or lack of experience could be the reasons of under- and over-estimation. Basing on our research in field of expert-related errors we propose expert involvement degree (EID) metric that indicates the level of technique automation and expert uncertainty degree (EUD) metric which is complex measure of experts decisions uncertainty within assessment. We propose usage of total expert trustworthiness degree (ETD) indicator as function of EID and EUD. Expert uncertainty assessment and Multi-FIT as FMEDA verification are implemented in AXMEA (Automated X-Modes and Effects Analysis) software tool. Proposed Multi-FIT technique in combination with FMEDA was used during internal activities of SIL3 certification of FPGA-based (Field Programmable Gate Array) RadICS platform for NPP I&C systems. The proposed expert trustworthiness degree calculation is going to be used during production activities of RPC Radiy (Research and Production Corporation). Our future work is related to research in expert uncertainty field and extension of AXMEA tool with new failure data sources as well as software optimization and further automation.

Abstract:
Currently, intelligent and connected vehicles(ICVS) have been gradually proven to be the next generation of mobility. With the rapid development of automobile electronization, intelligentization and networking, the scale and complexity of the in-car electronic system are increasing day by day, and its intelligent systems such as lane departure warning and active collision avoidance system are also becoming more and more common. These systems require a lower delay, higher bandwidth and more reliability for vehicle network. Traditional vehicular network architecture can no longer meet the demand for automatic driving, entertainment, Multimedia, remote Diagnostic and Software Update, etc. Higher requirements are put forward for the relevant capability of automotive network architecture. For example, HD cameras, lidar and millimeter-wave radars are widely used in autonomous driving systems, and the data transmission of HD cameras and lidar requires a higher communication speed and more reliable network architecture to serve vehicle users. In the research of ICVS, network security has been paid more and more attention. In the field of ICVS, any network security is related to life safety. Therefore, the consideration of network security in network architecture is so critical. At the same time, to make ICVS more reliable, redundant design in the network architecture is also very important. The traditional CAN network cannot support the development of network security, while CANFD can support the functions of encryption and message authentication, and CANFD's bandwidth is much higher than that of CAN network. Automotive Ethernet can also carry out corresponding network security design, and its bandwidth has reached 100Mbps which is continuously developing. At the same time, in-vehicle Ethernet proposes AVB and TSN protocols, which can provide extremely low delay for keyframes. The synchronization protocol IEEE802.1AS and multiple scheduling protocols of the in-vehicle Ethernet work together to ensure the real-time performance of the system. The full-duplex transmission function of automotive Ethernet can also support the redundancy of the network architecture better. This paper analyzes the traditional vehicular network architecture and the current mainstream network architecture research and related technologies. This paper discusses the development trend of vehicular network architecture in the future. In consideration of real-time, bandwidth, reliability and safety requirements, a redundant hybrid network architecture with Ethernet backbone for future intelligent networked vehicles(ICVS) is proposed in this paper.

Abstract:
Traffic related crashes cause more than 38,000 fatalities every year in the United States. They are the leading cause of death among drivers up to 54 years in age and incur $871 million in losses each year. Driver errors contribute to about 94% of these crashes. In response, automotive companies have been developing vehicles with advanced driver assistance systems (ADAS) that aid in various driving tasks. These features are aimed at enhancing safety by either warning drivers of a potential hazard or picking up certain driving maneuvers like maintaining the lane. These features are already part of vehicles with Driver Assistance Technology, and they are vital for successful deployment of connected and automated vehicles in the near future. However, drivers' responses to driving vehicles with advanced features have been meagerly explored. This research evaluates driver participants' response to scenarios when driving connected and automated vehicles compared to vehicles with and without Driver Assistance Technology. The research developed rural, urban, and freeway driving scenarios in a driver simulator and tested on participants sixteen years to sixty-five years old. The research team explored two types of advanced features by categorizing them into warnings and automated features. The results show that the advanced features affected driving behavior by making driver participants less aggressive and harmonizing the driving environment. This research also discovered that the type of driving scenario influences the effect of advanced features on driver behavior. Additionally, aggressive driving behavior was observed most in male participants and during nighttime conditions. Rainy conditions and female participants were associated with less aggressive driving behavior. The findings from this research help to assess driver behavior when driving vehicles with advanced features. They can be inputted into microsimulation software to model the effect of vehicles with advanced features on the performance of transportation systems, advancing technology that could eventually save millions of dollars and thousands of lives.

Abstract:
As automobiles morph from stand-alone mechanical objects to highly connected, autonomous systems with increasing amounts of electronic components. To manage these complex systems, some semblance of in-car decision-making is also being built and networked to a cloud architecture. This cloud can also enable even deeper capabilities within the broader automotive ecosystem. Unsettled Issues Regarding Autonomous Vehicles and Open-source Software introduces the impact of software in advanced automotive applications, the role of open-source communities in accelerating innovation, and the important topic of safety and cybersecurity. As electronic functionality is captured in software and a bigger percentage of that software is open-source code, some critical challenges arise concerning security and validation.

Full text
Abstract:
Many automotive industry safety advocates have been pushing for greater market penetration for active safety and advanced driver-assistance systems (ADAS), with the goal of ending deaths due to car crashes. However, there are far-reaching implications for the collision repair, specialty equipment, and performance aftermarket sectors—after a collision or modification, the ADAS system functionality must be preserved to maintain, driver, passenger, and road user safety. To do this, sensor recalibration and ADAS functional safety validation and documentation after repair, modification, or accessorizing are necessary. Unsettled Issues on Sensor Calibration for Automotive Aftermarket ADAS tackles the challenges of accelerating the pace of ADAS implementation; increasing industry understanding of systems, sensors, software, controllers; and minimizing the overwhelming variety of sensor calibration procedures and automaker targets. Additionally, this report addresses the liability concerns that are challenging the industry as it seeks to move forward safely.

Kolodziejczyk, Bart. Unsettled Economic, Environmental, and Health Issues of Ammonia for Automotive Applications. SAE International, October 2021. http://dx.doi.org/10.4271/epr2021022.

Full text
Abstract:
Ammonia has been previously trialed as an automotive fuel; however, it was hardly competitive with fossil fuels in terms of cost, energy density, and practicality. However, due to climate change, those practical and cost-related parameters have finally become secondary deciding factors in fuel selection. Ammonia is safer than most fuels and it offers superior energy densities compared to compressed or liquefied hydrogen. It is believed that ammonia might be an ultimate clean fuel choice and an extension to the emerging hydrogen economy. Unsettled Economic, Environmental, and Health Issues of Ammonia for Automotive Applications examines the major unsettled issues of using ammonia as a clean automotive fuel alternative, including the lack of regulations and standards for automotive applications, technology readiness, safety perception, and presently limited supply. While ammonia as a fuel is still in its infancy, identifying and addressing these challenges early could enable a safe and smooth transition.

Full text
Abstract:
Manufacturers and developers of automated vehicles (AVs) often maintain that no new infrastructure enablers are needed to achieve full AV deployment aside from existing infrastructure investments (e.g., connected traffic signals, designated stops, booking software, mobile applications, separated lanes). These groups hold that a state-of-good-repair and clean lane markings are sufficient; however, much of the US receives poor grades when it comes to these features. What do infrastructure owners and operators need to know about what constitutes effective lane markings or what to prioritize in terms of safety and mobility? How do policy considerations effect these choices? Automated Vehicles and Infrastructure Enablers the first in a series on AVs and infrastructure—considers ways in which infrastructure can speed or delay deployment, mitigate hazards, and capture benefits related to AV roll-out. Some of these benefits include accessibility, safety, reduced climate impacts, and integrated supply chain logistics.

Full text
Abstract:
The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous traffic conditions to improve the mobility and reliability of people and goods. A 4-mile stretch of the Blue Line light rail transit (LRT) extension, which connects Old Concord Rd and the University of North Carolina at Charlotte’s main campus on N Tryon St in Charlotte, North Carolina, was considered for travel time reliability analysis. The influence of crosswalks, sidewalks, trails, greenways, on-street bicycle lanes, bus/LRT routes and stops/stations, and street network characteristics on travel time reliability were comprehensively considered from a multimodal perspective. Likewise, a 2.5-mile-long section of the Blue Line LRT extension, which connects University City Blvd and Mallard Creek Church Rd on N Tryon St in Charlotte, North Carolina, was considered for simulation-based operational analysis. Vissim traffic simulation software was used to compute and compare delay, queue length, and maximum queue length at nine intersections to evaluate the influence of vehicles, LRT, pedestrians, and bicyclists, individually and/or combined. The statistical significance of variations in travel time reliability were particularly less in the case of links on N Tryon St with the Blue Line LRT extension. However, a decrease in travel time reliability on some links was observed on the parallel route (I-85) and cross-streets. While a decrease in vehicle delay on northbound and southbound approaches of N Tryon St was observed in most cases after the LRT is in operation, the cross-streets of N Tryon St incurred a relatively higher increase in delay after the LRT is in operation. The current pedestrian and bicycling activity levels seemed insignificant to have an influence on vehicle delay at intersections. The methodological approaches from this research can be used to assess the performance of a transportation facility and identify remedial solutions from a multimodal perspective.

Investigation on Design and Analysis of Passenger Car Body Crash-Worthiness in Frontal Impact Using Radioss. SAE International, September 2020. http://dx.doi.org/10.4271/2020-28-0498.

Full text
Abstract:
Increasing advancement in automotive technologies ensures that many more lightweight metals become added to the automotive components for the purpose of light weighting and passenger safety. The accidents are unexpected incidents most drivers cannot be avoided that trouble situation. Crash studies are among the most essential methods for enhancing automobile safety features. Crash simulations are attempting to replicate the circumstances of the initial crash. Frontal crashes are responsible for occupant injuries and fatalities 42% of accidents occur on frontal crash. This paper aims at studying the frontal collision of a passenger car frame for frontal crashes based on numerical simulation of a 35 MPH. The structure has been designed to replicate a frontal collision into some kind of inflexible shield at a speed of 15.6 m/s (56 km/h). The vehicle’s exterior body is designed by CATIA V5 R20 along with two material properties to our design. The existing Aluminum alloy 6061 series is compared with carbon fiber IM8 material. The simulation is being carried out by us in the “Radioss” available in “Hyper mesh 17.0” software. The energy conservation and momentum energy absorption are carried out from this dynamic structural analysis.
