Filter by Keyword60 report(s) found with highway safety in the keywords field 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... 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... Improving roadway safety on Indian reservations requires a comprehensive approach. Limited resources, lack of crash data, and few cross-jurisdictions coordination has made it difficult for Native American communities to address their roadway safety concerns. A methodology to improve roadway safety has... The sharp increase in travel volumes, shift in traffic mix, and large increases in crashes have transformed the travel environment in the oil region of western North Dakota. Roads once used for local access and agricultural purposes now mostly serve expanding oil production. Oil companies, workers, commercial... With the understanding that seat belts are a relatively low-cost safety device, and are an easy primary protection for occupants in passenger vehicles, North Dakota has chosen to continue to measure rural roads seat belt use. The U.S. Department of Transportation works with states to measure seat belt... The high societal cost of roadway crashes nationwide makes improving highway safety an important objective of transportation agencies. Recognizing this, Safety Management Systems (SMS) have been required by the Federal Highway Administration (FHWA) to encourage states to pursue and promote safety and... |
