Filter by Keyword118 report(s) found with traffic in the keywords field This study evaluated the approach-level safety performance of left-turn phases at signalized intersections, including permissive, protected-permissive (PPLT), protected indications, and flashing yellow arrow (FYA). Data collection included exact dates of traffic signal changes, high-resolution datasets... Studies of self-regulation suggest that monitoring is essential for task performance and the attainment of goals. Research was conducted to investigate factors affecting the monitoring of driving and driving safety. Participants drove on a simulator course while discussing emotional topics or daily routines.... Due to the current limitations on seismic forecasting, there is a high chance that a considerable number of vehicles would remain on a bridge when an earthquake occurs. In traditional seismic analyses, traffic loads were often ignored. Existing mode-based bridge-traffic interaction analysis usually cannot... The State of Wyoming road network is characterized by heavy truck traffic. In 2015, truck traffic was approximately 22% of vehicle miles traveled (VMTs) along all routes in Wyoming, according to the WYDOT Annual Traffic Report. The heaviest truck traffic exists along I-80 with about 47% truck VMTs. Trucks... Long-span bridges support a large amount of traffic every day. Even when an earthquake strikes, a long-span bridge often still has many vehicles present due to the low predictability of earthquake events. To study the seismic performance of bridge and traffic systems, a new full-response prediction methodology... Child pedestrians are some of the most vulnerable users of our transportation systems, and they deserve particular attention when we consider traffic safety. Part 1 of this report identifies locations in urban areas where child pedestrians are at particular risk for fatal collisions with vehicles. We... 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... In recent years, Bus Rapid Transit (BRT) systems have been gaining increasing popularity because of their effectiveness in improving urban mobility. The Utah Transit Authority (UTA) is the primary public transit provider in Salt Lake City and has implemented a 10.8-mile BRT route along 3500/3300 South... 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... |
