Abstract:
A mechanical system superelement that represents spatial dynamics of high mobility track vehicle suspension systems is derived. Using results from a companion paper [1], the equations of motion for a suspension system with an arbitrary number of road wheels are systematically derived. Track is represented as a complex internal force element that acts between ground, wheels, and the chassis of the vehicle. Track tension is computed from a relaxed catenary relationship and track bridging effects are modeled. Numerical results for driver acceleration and absorbed power, as well as track tension are presented. A factor of 90 decrease in compute time is achieved over a comparable multibody model of the same vehicle.

Abstract:
Within the Mobility Choices (MC) project we have developed an app that allows users to record their travel behavior and encourages them to try out new means of transportation that may better fit their preferences. Tracks explicitly released by the users are anonymized and can be analyzed by authorized institutions. For recorded tracks, the freely available app automatically determines the segments with their transportation mode; analyzes the track according to the criteria environment, health, costs, and time; and indicates alternative connections that better fit the criteria, which can individually be configured by the user. In the second step, the users can edit their tracks and release them for further analysis by authorized institutions. The system is complemented by a Web-based analysis program that helps authorized institutions carry out specific evaluations of traffic flows based on the released tracks of the app users. The automatic transportation mode detection of the system reaches an accuracy of 97%. This requires only minimal corrections by the user, which can easily be done directly in the app before releasing a track. All this enables significantly more accurate surveys of transport behavior than the usual time-consuming manual (non-automated) approaches, based on questionnaires.

Abstract:
Wheeled walking mechanism has the advantages of high mobility and low rolling resistance, but it is easy to sink and slip when working in soft and muddy terrain. Tracked walking mechanism has the advantages of high passability and stability, but it has the problems of difficult steering and slow walking speed. In order to make the walking mechanism possess a combination of passability, stability, and mobility, a coordinated variable wheel-track walking mechanism was designed. The coordinated variable triangle track can change the landing area through the deformation structure to improve the ability of the walking mechanism to adapt to different terrains. The kinematics equation of the wheel-track walking mechanism was established, and the front wheel steering angle equation during motion was derived. Based on RecurDyn software, the motion simulation of the walking mechanism was carried out under the conditions of straight walking and turning on the flat ground, climbing hillsides, and crossing ditches. The simulation results show that the coordinated variable wheel-track walking mechanism has the mobility of wheeled walking mechanism and the passability and stability of the tracked walking mechanism. The stability and climbing ability of the wheel-track walking mechanism was better when the coordinated variable triangle track in the stretch state, and the mobility and steering ability was better in the contraction state.

Abstract:
Introduction. Involvement in global information flows, holding major international events in Russia, focusing on interaction with foreign universities and partners creates conditions for the formation of modern youth's focus on the global track of mobility – admission to educational organizations of foreign countries. At the same time, role and quality of education in Russia in the global market are increasing through the development of Russian education, internationalization and networking of universities. Such tendencies to increase mobility in education naturally require a study of the prevalence of the ideas of mobility in general and in certain areas among schoolchildren and university students. The aim of the study is to reveal the prevalence of the ideas of mobility (potential mobility), both within Russia and abroad, among graduates of educational institutions (at different levels). Materials and research methods. The study involved 1136 graduates of educational institutions in Ekaterinburg, of which 30% are graduates of secondary schools, lyceums and gymnasiums, 60% are graduates of bachelor's degrees from 4 universities, and 10% are graduates of master's degree from 3 universities. Research results. A study conducted in 2020–2021 indicated the following trends: the higher the level of education, the higher the value of the educational environment in the country of residence, the more broadly represented the national track of mobility (schoolchildren – 46%, bachelors – 51%, masters – 54%). Among the global market of educational services for all graduates of educational institutions in Russia, priority is given to Europe. Among bachelors, there are more of those who are confident that they can find the desired job in Russia (21%) than in another country. Master students are more confident in the possibilities of working in their specialty in Russia (36%). The older the graduate becomes, the more rational motives prevail in the track of mobility. Conclusion. The study of potential mobility allows us to conclude that the predominance of the national track of mobility is directly proportional to growing up, the older the respondent, the more rationally he approaches the choice of a further place of study and residence, taking into account the possibilities, both intellectual and financial. Thus, it becomes obvious why sufficiently high figures of potential mobility do not become as high indicators of real educational and labor emigrations.

Abstract:
After going through the milestones that have marked the logistical transformation and the rise of containerisation, the thesis focuses on two different but assimilable emergency contexts for the use of the same matrix and rationality of government. The Roja Camp of Ventimiglia on the Italian-French border, an area dedicated to the containment of transit and asylum seekers managed since 2016 by the Italian Red Cross and the container village of Tolentino in Marche region, strongly affected by the earthquake of 2016/2017, responsible for the reception of displaced persons. The attention is devoted to the dimension of living and the administrative management practices, tracing the violence hidden in a circulatory government that extracts value from mobility of subjects. Two spaces "not completely opened" and "not completely enclosed", expression of a governmentality that exploits the absence of a specific normative provision. Two places where the container becomes the setting of a process of othering, in the time of the emergency.

Abstract:
Cette dernière décennie, nous avons pu constater une montée en popularité des applications mobiles basées sur la localisation des téléphones. Ces applications collectent des traces de mobilité qui retracent le déplacement des utilisateurs au cours du temps. Dans le projet régional DA3T, nous faisons l’hypothèse que l’analyse des traces de mobilité de touristes peut aider les aménageurs dans la gestion et la valorisation des territoires touristiques. L’objectif est de concevoir des méthodes et des outils d’aide à l’analyse de ces traces. Cette thèse s’intéresse au traitement des traces de mobilité et propose une plateforme modulaire permettant de créer et d’exécuter des chaînes de traitement sur ces données. Au fil des modules d’une chaîne de traitement, la trace de mobilité brute évolue en trajectoires sémantiques. Les contributions de cette thèse sont : (i) un modèle de trajectoire sémantique multi-niveau et multi-aspect et (ii) deux mesures calculant la similarité entre deux trajectoires sémantiques s’intéressant aux dimensions spatiales, temporelle et thématique. Notre modèle (i) est utilisé comme modèle de transition entre les modules d’une chaîne de traitement. Nous l’avons mis à l’épreuve en instanciant des trajectoires sémantiques issues de différents jeux de données de domaines variés. Nos deux mesures (ii) sont intégrées à notre plateforme comme modules de traitement. Ces mesures présentent des originalités : l’une est la combinaison de sous-mesures, chacune permettant d’évaluer la similarité des trajectoires sur les trois dimensions et selon trois niveaux de granularité différents, l’autre est la combinaison de deux sous-mesures bidimensionnelles centrées autour d’une dimension en particulier. Nous avons évalué nos deux mesures en les comparant à d’autres mesures et à l’avis de géographes
Over the last decade, we have seen a rise in popularity of mobile applications based on phone location. These applications collect mobility tracks which describe the movement of users overtime. In the DA3T regional project, we hypothesise that the analysis of tourists’ mobility tracks can help planners in the management and enhancement of tourist areas. The objective is to design methods and tools to help analyse these tracks. This thesis focuses on the processing of mobility tracks and proposes a modular platform for creating and executing processing chains on these data. Throughout the modules of a processing chain, the raw mobility track evolves into semantic trajectories. The contributions of this thesis are: (i) a multi-level and multi-aspect semantic trajectory model and (ii) two measures that compute the similarity between two semantic trajectories along spatial, temporal and thematic dimensions. Our model (i) is used as a transition model between modules of a processing chain. We tested it by instantiating semantic trajectories from different datasets of various domains. Our two measures (ii) are integrated in our platform as processing modules. These measures present originalities: one is the combination of sub-measures, each allowing to evaluate the similarity of trajectories on the three dimensions and according to three different levels of granularity, the other is the combination of two bidimensional sub-measures centred around a particular dimension. We evaluated our two measures by comparing them to other measures and to the opinion of geographers

Abstract:
The corticospinal tract is one of the major motor tracts in the spinal cord. Traumatic injury to it through spinal cord injury or stroke results in loss of dexterity, coordinated locomotion and fine motor function. With time the spinal circuitry adapts, which may result in spasticity. This thesis is a characterisation of a corticospinal tract injury in a rodent model and evaluates three different treatments, which aim to improve functional recovery post-injury. The first result chapter describes the unilateral pyramidotomy surgery, which lesions the corticospinal tract at medullary level in the brainstem. I performed different behavioural tests assessing motor and sensory function, which revealed sustained deficits. Furthermore, I developed 3 different neurophysiology protocols, which assess functional neurophysiological recovery following sprouting of the uninjured corticospinal tract. I found direct cortical stimulation in combination with EMG recordings from a forelimb muscle (the extensor carpii radialis) is most suitable for longitudinal neurophysiological monitoring of corticospinal tract plasticity. Two of the result chapters evaluate two different gene therapies, which modulate intrinsic neuronal properties. In each, we transduced the motor cortex with a regeneration-associated gene. First, we overexpressed protein tyrosine phosphatase, non-receptor type 2, which also may act as a transcription factor. I performed a unilateral pyramidotomy lesion and treated the unaffected corticospinal tract to increase sprouting. The second gene therapy we tested was with ribonuclease inhibitor 1, which inhibits ribonucleases that are degrading RNA. I performed a cervical lateral hemisection and treated the lesioned corticospinal tract to increase regeneration. To assess if these treatments were effective, I performed behavioural testing, neurophysiology and immunohistochemistry. Both treatments, with Ptpn2 and RNH1, improved functional recovery, neurophysiological outcomes and increased plasticity. In the last result chapter, I performed a bilateral corticospinal tract lesion/pyramidotomy, which causes spasticity through spinal circuitry maladaptations. First, I characterised spasticity behaviourally by developing a new open-field scoring system, neurophysiologically with two different preparations assessing reflex pathways and anatomically by looking at excitatory and inhibitory spinal networks. Next, I treated these rats with intramuscular neurotrophin-3, which is developmentally important for patterning of spinal reflex pathways. Rats had reduced spasticity and improved functional locomotor recovery. In conclusion, I have evaluated three different treatments after corticospinal tract injury, which all improved functional, neurophysiological and anatomical outcomes.

Abstract:
This research investigate the geochemical environmental impact of ancient ash deposits erupted to hundreds of thousands to several million years ago in the southern Puna and neighbouring areas (Argentina), Uruguay and five historical eruptions occurred over a 20-year period in the Andes. In the latter case, pristine ash samples of Cophue, 2000, Lonquimay, 1988, Llaima, 2008, Chaiten, 2008, and Hudson, 1999 eruptions were studied. The main purpose of this research is to investigate the geochemical environmental hazard posed by different types of volcanic ashes in general, and from the Andes, in particular. The specifics aims of this research are:(1) to develop an analytical methodology for the physico-chemical characterisation of volcanic ash;(3) to propose a new ash leaching methodology that can be useful both for recent and ancient volcanic ashes (Single Batch Leaching Test, SBLT);(4) to recognize the geochemical impact occurring after the deposition of volcanic ash on the environment through leaching experiments (Batch leaching tests, Column leaching tests, and Sequential Extraction Scheme). The main conclusions extracted from this research can be summarised as follows:(1) The physico-chemical information of ashes (mainly the morphological features by SEM, grain-size distribution by laser diffraction and Potential toxic trace elements identification and quantification of the bulk ashes) highlights the main environmental concerns related to the studied ashes and it lays the foundation of the basic knowledge required to understand the ash leaching. (2) The main body of this research has been to propose a proved methodology for a single batch leaching test (SBLT) with deionised water in order to obtain information on short term leaching behaviour of volcanic ash identifying, qualitatively and quantitatively, the potentially hazardous elements being rapidly released from both recently erupted and ancient volcanic ashes. The proposed procedure is completed within few hours and its design is simple, concise and reliable.(3) The application of the SBLT (with deionised water) method developed in this research have allowed to define the potential geochemical impact of the volcanic ashes investigated on the environment. This study shows that major elements with high mobility are Ca, Mg, Na, Si, K, and Al. Puna and Uruguay ashes could release in the environment the same trace elements (i.e., P, Ti, Fe, Mn, Zn), however, in different concentrations. These are macro- and micronutrients evidencing the fertilizing potential of the ashes. Chaiten ashes showed high concentrations for As, Pb, Fe, and Zn, whilst the other samples (i.e., COP, LON, LLA, and HUD) could release principally P, Ti, Mn, Ni, Zn, and Pb. Most of these are potentially toxic trace elements (PTTE) even at very low concentration. They are included in the drinking water guidelines due to their potential toxicity and must be especially monitored in the environmental assessment of these ashfall deposits. (4) Dynamic leaching tests conducted on raw ashes and grain-size fractions allowed to define the element implied during glass and mineral dissolution. From the data nowadays available on the temporal leaching of Andean rhyolitic ashes (from CVZ to SVZ), the association between ash dissolution and some trace elements (As, Mo, V, B, and U) through laboratory experiments was demonstrated. This study represents a great advance on the knowledge of the geochemical environmental hazard posed by volcanic ashes, in general, and from the Andes, in particular. In terms of methodological approach, the developed method of SBLT is a very important contribution because there is a need to harmonize the batch tests applied to volcanic ash. In addition, column leaching test and sequential extraction scheme complement the information obtained by SBLT and facilitate decision making on management of geochemical hazard associated with the volcanic ash fall.

Abstract:
High pH leachates can mobilise oxyanion forming elements from alkaline waste, such as iron and steel slags and bauxite ore processing residue, into the wider environment. Red mud is a highly alkaline waste product from bauxite ore processing. It contains elevated concentrations of oxyanion forming elements such as Al, As, V and Mo that are mobilised at high pH together with other trace metals including Cu and Ni. The red mud spill at Ajka, Hungary released 1 million m3 of caustic red mud into the surrounding area. As part of the initial clean-up, some thinner red mud deposits (< 5 cm) were ploughed into fields to prevent dust formation whereas wetland areas were left untreated. This study used aerobic and anaerobic batch microcosms together with XAS spectroscopy, (HPLC)-ICP-MS and solid phase extraction techniques to investigate the effects of red mud addition to unaffected soils with respect to biogeochemical processes and trace element release. Experiments were designed to be analogous to soil conditions following the remediation efforts. The results showed that the effect of red mud addition to soils was highly dependent upon soil properties, experimental pH, and total organic carbon (TOC) content. As and V were found to be persistently mobile under both aerobic and anaerobic conditions. Red mud addition to soils with a high TOC content mobilised high aqueous concentrations of organic matter complexing metals such as Cu, Ni and V under anaerobic conditions. Gypsum addition to red mud affected soils showed a reduction in aqueous oxyanion concentrations compared to soils with red mud addition alone indicating that it is potential ameliorant for red mud contaminated soils. The results showed that the extensive remediation efforts by the Hungarian authorities were justified but that red mud should be used with caution as a soil amendment.

Abstract:
The long-term mobility and availability of trace metals has been cited as a potential hazard by critics of EPA 503 rule governing the land application of biosolids. The purpose of this research was to investigate the long-term effects of biosolids application on trace metals distribution and mobility. A single application of aerobically digested biosolids was applied to 1.5 x 2.3 m confined plots of a Davidson clay loam (clayey, kaolinitic, thermic, Rhodic Paleudult) in 1984 at 0, 42, 84, 126, 168, and 210 Mg/ha. The highest biosolids application supplied 4.5, 760, 43, and 620 kg ha-1 of Cd, Cu, Ni, and Zn, respectively. Radish (Raphanus sativus L.), lettuce (Lactuca sativa Var longifolia) and barley (Hordeum vulgare) were planted at the site. Soils were sampled to a depth of 0.9 m and sectioned into 5 cm increments after separating the Ap horizon. Total (EPA 3050B), available (Mehlich-I), sequential extraction, and dispersible clay analyses were performed on samples from the control, 126 Mg/ha and 210 Mg/ha treatments. Extractable (0.005 DTPA, 0.01 M CaCl2, and Mehlich-1) Cd, Cu, Ni, and Zn were measured on 15 cm-depth samples from each plot. Simple linear regression between plant metal concentration and biosolids-added trace metals were computed to determine uptake coefficients (UC) of crops for each metal as outlined by USEPA Part 503 Rule. Results indicated that more than 80% of the applied Cu and Zn are still found in the topsoil where biosolids were incorporated with slight enrichment down to 0.3 m. Biosolids application increased the concentration of trace metals in all the extracted fractions, with a large proportion of Zn and Cd present in the available forms. The major portion of Cu, Zn and Ni was associated with the metal-oxides fraction. Biosolids treatments had no significant effect on the yield of the crops. Plant uptake of trace metals differed among crops. Plant tissue metal concentrations increased with biosolids rate but were within the normal range for these crops. Trace metals concentration in plants generally correlated well with their concentrations extracted with 0.005 M DTPA, 0.01 M CaCl2 and Mehlich-1. Mehlich-1 gave the highest correlation coefficients for Cu and Zn and, therefore, was the most reliable in predicting their availability and uptake by the crops grown. Availability of trace metals as measured by Mehlich-I, DTPA, and CaCl2 extraction were higher in amended plots as compared to the control and increased linearly in response to biosolids addition. Metal concentration in the plants exhibited a plateau response in most cases. Several linear increases were observed in some cases in 2003 when the soil pH decreased below 5.5. The uptake coefficients values generated for the different crops were in agreement with the values set by the Part 503 Rule.

Abstract:
AbstractThis chapter is an autobiographic reflection of my academic track, with a focus on the theory of the institutionalization of regions, outlined in the 1980s in the context of the ongoing socio-spatial theory debates in geography. The chapter discusses how working in a peripheral university positioned this research. The chapter also reflects the academic influences and the theory behind the theory of the institutionalization of regions. It then charts the “travel” of this theory outside of Finland. By discussing the debates on the Anglophone hegemony in geography, the chapter also reflects the role of “mediators” behind the possible mobility of theories, as well as the motives of scholars to contribute to theoretical debates.

Abstract:
Robotic vehicles are an attractive alternative to manned vehicles in hazardous or dangerous off road and urban environments. Present designs of robot vehicles employ wheels or tracks as the running gears and, in general, tracks provide superior mobility on rough or uneven terrain. This paper presents a multibody dynamics model of a tracked robotic vehicle for the purpose of predicting mobility in two different scenarios: 1) steep terrains, and 2) urban terrains in the form of staircases. In both scenarios we study the physical limitations on vehicle mobility imposed by key vehicle design variables and vehicle operating conditions. Example vehicle design variables include the location of the mass center, grouser penetration, and track/terrain friction. Example vehicle operating conditions include climbing under full versus partial track/terrain contact, and climbing on straight versus switch back courses.

Abstract:
Abstract In this paper, dynamic track tension for high mobility tracked vehicle is investigated by multibody dynamic simulation techniques. This research focuses on a heavy military tracked vehicle which has sophisticated suspension and rubber bushed track systems. In order to obtain accurate dynamic track tension of track subsystems, each track link is modeled as a body which has six degrees of freedom. A compliant bushing element is used to connect track links. Various virtual proving ground models are developed to observe dynamic changes of the track tension. The dynamic track tensions are monitored at several stationary hull points and points on the track link itself. The effects of pre-tensions, traction forces, turning resistances, sprocket torques, ground profiles, and vehicle speeds, for dynamic responses of track tensions are explored, respectively. Numerical studies of the dynamic track tension are validated against the experimental measurements.

Full text
Abstract:
As electric mobility is expanding at a rapid pace, the standardized availability of gas stations compared to a scarcity of charging stations continues to be the greatest challenge for electric vehicles. With cities, university campuses and businesses promoting electric vehicle infrastructure and incentives, it is necessary to develop key performance metrics and visualizations that can track the utilization of the charging infrastructure. This study performs a manual data collection at dedicated plug-in charging stations across Purdue University to assess their utilization. Approximately 2,800 observations were conducted over 50 days across seven level 2 plug-in charging stations. Results showed that for large portion of the observations, vehicles were parked at the spots (40%) but not plugged in. Vehicles plugged in to charging stations accounted for 34% of observations. Charging station spots were vacant for 25% of observations indicating that current infrastructure meets the demand. There were 74 unique vehicles that used the spots, of which 27% were plugged in more than 10 times. Illegally parked vehicles accounted for less than 1% with only 4 repeat offenders who used these spots more than once. As electric deployment continues to increase, performance metrics will be an integral tool for agencies and decision makers to help with the maintenance and expansion of electric vehicle infrastructure.

Abstract:
The California Freight Mobility Plan 2020 lists the Los Angeles-Inland Empire trade corridor region as a prominent industrial hub experiencing an increase in freight flows. The California Freight Mobility Plan also regards automated truck platoon (ATP) as an emerging opportunity to minimize congestion on the trade corridor routes. Percentage change in accessibility from 2022 (“without” ATP) to 2040 (“with” ATP) is calculated for the eighteen industry sectors of the Los Angeles-Inland Empire trade corridor. The application of the accessibility formulation was carried out with data on travel time from I-710 and I-10 within Los Angeles County. The findings suggest that all the industry sectors have a very high positive percentage change in accessibility by transforming from “without” to “with” ATP deployment-based accessibility. In the vicinity of the prominent freight corridors of I-710 and I-10 within Los Angeles County, notably, the largest increase in accessibility above 90% will be observed for the industry sectors of Agriculture, Forestry, Fishing and Hunting, Health Care and Social Assistance, Finance and Insurance, Transportation and Warehousing, and Retail Trade of the Los-Angeles-Inland Empire. Thus, these findings suggest the deployment of ATP on specific freight routes to enhance and sustain economic activity across the Los Angeles-Inland Empire trade corridors.

Full text
Abstract:
Truck platooning has many benefits over traditional truck mobility. Literature shows that platooning improves safety and reduces 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. Deployment of truck platooning within interstate highways would result in significant fuel savings, but may have a direct impact on flexible pavement performance. The channelization of the platoon and reduced rest time between consecutive loads would accelerate the damage accumulation at the channelized position. Ultimately, this would lead to pavement service life reduction and a subsequent increase in maintenance and rehabilitation costs. Therefore, the main objective of this project is to quantify the effects of platooning on flexible pavements and provide guidelines for the state of Illinois by considering the aforementioned factors. Although the benefits of platooning are quantifiable, not every truck route is platoonable. For efficient platooning, trucks need to travel at a constant high speed for extended distances. The integrity of the platoon should be preserved because interfering vehicles would compromise the platooning benefits and road safety. An introduced high-level approach considers the volume/capacity of a roadway and the expected number of highway exit and entry conflicts. Using these parameters, each roadway section is assigned a level of platoonability, ranging from one to five—with five being the highest. A framework was developed to analyze the Illinois highway network. It was found that 89% of the network highway is platoonable under average capacity conditions.

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:
Trucks serve significant amount of freight tonnage and are more susceptible to complex interactions with other vehicles in a traffic stream. While traffic congestion continues to be a significant ‘highway’ problem, delays in truck travel result in loss of revenue to the trucking companies. There is a significant research on the traffic congestion mitigation, but a very few studies focused on data exclusive to trucks. This research is aimed at a regional-level analysis of truck travel time data to identify roads for improving mobility and reducing congestion for truck traffic. The objectives of the research are to compute and evaluate the truck travel time performance measures (by time of the day and day of the week) and use selected truck travel time performance measures to examine their correlation with on-network and off-network characteristics. Truck travel time data for the year 2019 were obtained and processed at the link level for Mecklenburg County, Wake County, and Buncombe County, NC. Various truck travel time performance measures were computed by time of the day and day of the week. Pearson correlation coefficient analysis was performed to select the average travel time (ATT), planning time index (PTI), travel time index (TTI), and buffer time index (BTI) for further analysis. On-network characteristics such as the speed limit, reference speed, annual average daily traffic (AADT), and the number of through lanes were extracted for each link. Similarly, off-network characteristics such as land use and demographic data in the near vicinity of each selected link were captured using 0.25 miles and 0.50 miles as buffer widths. The relationships between the selected truck travel time performance measures and on-network and off-network characteristics were then analyzed using Pearson correlation coefficient analysis. The results indicate that urban areas, high-volume roads, and principal arterial roads are positively correlated with the truck travel time performance measures. Further, the presence of agricultural, light commercial, heavy commercial, light industrial, single-family residential, multi-family residential, office, transportation, and medical land uses increase the truck travel time performance measures (decrease the operational performance). The methodological approach and findings can be used in identifying potential areas to serve as truck priority zones and for planning decentralized delivery locations.
