This study is considered a first step toward validating applicability of the Highway Safety Manual (HSM) Part D to Wyoming conditions. The HSM Part D provides a quantitative measure of safety for various countermeasures known as crash modification factors (CMF). These CMFs are provided for four distinct...

 

Traditional pedestrian and bicyclist safety analyses typically examine crashes, injuries, or fatalities. However, this reactive approach only accounts for the places where people are currently walking or biking and those that are doing so. Would a proactive approach – examining areas where pedestrian...

 

Despite bicycling being considered on the order of ten times more dangerous than driving, the evidence continues to build that high-bicycling-mode-share cities are not only safer for bicyclists but for all road users. This paper looks to understand what makes these cities safer. Are the safety differences...

 

Building upon the development of a measure of safety culture based on a simplified two-factor model of meaning and behavior, a further validation study of the safety culture instrument was undertaken. The Safety Culture Assessment Survey (SCAS) was administered to a large regional railroad organization...

 

The purpose of the initial project was to establish a baseline for the evaluation of proposed fatigue mitigation efforts, to demonstrate the utilization of measures of sleep and fatigue, and to gather initial data for comparison to other previous studies. Results demonstrated that there was enough data...

 

As the population grows and travel demands increase, alternative interchange designs have become increasingly popular. The diverging diamond interchange is an alternative design that has been implemented in the United States. This design can accommodate higher and unbalanced flow and improve safety at...

 

Over the last two decades, the use of advanced scientific and data-driven statistical methods has been continuously evolving to reduce the frequency and severity of crashes on our roadways. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) was...

 

A study was conducted to investigate why people talk on a cell phone while driving and why they also support legislation to restrict this practice. Participants completed a survey about their driving attitudes, abilities, and behaviors, and performed the OSPAN task. They reported using cell phones for...

 

Multitasking may diminish the self-awareness of performance that is often essential for self-regulation and self-knowledge. Participants in an experiment drove on a simulator while talking or not talking on a cell phone. The errors they made while driving were recorded. Following previous research, participants...

 

For highways located in different counties and cities across the country, specific conditions of weather, terrain, traffic characteristics, highway conditions, population and economic development are all different. Driving environments, traffic accidents and injury risks have strong interactions, which...
