By a process of field studies roads in the cryolithic zone main types defects and destructions asphalt concrete pavements related to mechanical load from vehicle wheels were identified. The dominant deformations that form warm cold seasons year, as well factors causing them, determined. It was found that, regardless temperature any arbitrary transverse road profile, on traffic rut car wheel has...

The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitat...

work-related musculoskeletal disorders (wmsds) are common among drivers and official workers. musculoskeletal disorders are frequent causes of absenteeism in many countries. the aim of this study was to determine the prevalence of musculoskeletal disorders and risk factors associated with these symptoms. a total of 346 workers and truck drivers were participated in this case-control study. all ...

Freight trucks are an important component of the nation s highway traffic. Due to their physical and operational characteristics, they can significantly impact traffic system performance, safety, and the travel experience of non-truck drivers. Methodological gaps exist in the literature on modeling car–truck interactions that do not result in crashes, especially those resulting from non-truck d...

OBJECTIVE This study aimed to determine if occupational exposure to whole-body vibration is associated with cervical intervertebral disc herniation among container truck drivers. METHODS We conducted a walk-through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading...

This paper examines the determinants of truck accidents in the United States using a time series data set covering the period 1970–2001. Along with other factors, the effect of the Motor Carrier Act of 1980, which deregulated the trucking industry, is examined for its impact on truck accidents. In addition, the model accounts for the effect railroad freight mileage has on truck accidents. Empir...

We deployed a recently proposed single loop detector based, real-time freeway truck traffic volume estimation algorithm to a County-level traffic database. The scale-up of the algorithm is achieved by adding an extra layer, consisting of a spatial filtering component for removing noise and an aggregation component for efficient analysis. All calculations could be done in real-time to produce a ...

This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...

The Ports of Long Beach and Los Angeles are the largest container port complex in North America and fifth largest in the world. Growth in U.S. Pacific Rim trade has put pressure on the landside transportation systems serving these two ports. In order to address this growth and mitigate environmental impacts, the ports are implementing new operational strategies and infrastructure improvements. ...

This study examined Chinese truck drivers' attitudes toward receiving feedback about their driving performance by in-cab technology and explored the best ways of providing feedback to truck drivers in China. The similarities and differences between US and Chinese drivers were also compared. Survey data were collected from 200 long-haul truck drivers in China to provide quantitative information....
