BACKGROUND A significant proportion of road traffic crashes are attributable to alcohol and marijuana use while driving globally. Sale and use of both substances is illegal in Pakistan and is not considered a threat for road traffic injuries. However literature hints that this may not be the case. We did this study to assess usage of alcohol and marijuana in Pakistani commercial drivers. METH...

This paper presents a haul truck alignment monitoring system that provides early warning signals to the operator when the truck is about to lose control. It is considered that a truck is in this condition when it crosses the centre of the road or veers to the side of the road at speed in an uncontrolled manner. The system provides different level of warnings to the driver and other haul trucks ...

The article highlights the problem of occupational safety a technological truck driver by improving process determining level risk studying relationships between various external and internal hazards. A special algorithm is proposed, main difference which from known ones procedure for analyzing causes dangerous factors, it proposed to use “Decision-Making Trial Evaluation” method (further...

Driver fatigue, recognized as a major safety problem in the transportation industry, is strongly influenced by employee work and sleep schedules. The work and rest hours of truck drivers have been regulated by Hours-of-Service (HoS) rules in the U.S since 1938, but it has become increasingly apparent these rules are inconsistent with the science of sleep and fatigue. We present and assess an in...

The impact of cellular telephone use on driver performance was tested using an interactive driving simulator. While drivers followed a 15-mile route containing curves, obstacles and signs, they sent and received mobile calls and tuned a radio. Type of cellular telephone varied (i.e., manual dialing/ hand-held: memory dialing/hands-free; or voiceactivated/hand-held), as did cellular telephone mo...

95 THE CANADIAN HIGHWAY NETwork consists mainly of two-lane highways where passing slower cars requires traveling in the lane assigned to the opposite traffic. Therefore, studying the mechanism of the passing maneuver is important for maintaining traffic safety, as well enhancing the highway’s level of service. Models for passing maneuvers are available in the design guides1,2 while different v...

INTRODUCTION Road traffic injury (RTI) has assumed major public health importance world-wide and the burden is heavier on the health-care infrastructure of countries in Sub-Saharan Africa. In Nigeria, RTI is the leading cause of trauma related morbidity and mortality. While there are some published epidemiological reports on RTI in the region, studies on the mechanism of causation of road traff...

Wrong-way driving (WWD) crashes lead to severe injuries and fatalities, especially when a large truck is involved. This study investigates the factors associated with crash-injury severity in large-truck WWD Florida. Various driver, roadway, weather, traffic characteristics were explored as explanatory variables through random parameter ordered logit model. The also accounted for heterogeneity ...
