Filter by Keyword113 report(s) found with traffic in the keywords field 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... Perception-reaction times (PRT) and deceleration rates are critical components in the design of highways and streets. This research has several objectives, including 1) evaluate differences in PRT and deceleration rates between crash and near-crash events, 2) assess the correlation between PRT and deceleration... Concrete bridge decks are directly exposed to daily traffic loads and may experience some surface cracking caused by excessive stress or fatigue accumulation, which requires repair or replacement. Among typical bridges in North America, bridge decks are considered the most expensive component to construct... Transportation systems generate certain health-promoting benefits such as access to social, economic, and cultural resources, but they also are a source of air pollution, noise, safety hazards, and barriers that diminish social cohesion in neighborhoods. Streets, in particular, are among the most important... Local transportation agencies in the Salt Lake City (SLC) Metropolitan Area spent more than a decade working toward building a sustainable regional transportation system. Light Rail Transit (LRT) is an integral part of that system. Currently, three LRT lines operate along the Wasatch Front area. A new... This report describes methods that potentially can be incorporated into the performance monitoring and planning processes for freeway performance evaluation and decision making. Reliability analysis was conducted on the selected I-15 corridor by employing congestion frequency as the performance measure.... |
