Filter by Keyword15 report(s) found with traffic crashes in the keywords field The American Indian population is at high risk for motor vehicle (MV) crash injury. Although preventable, a majority of these indigenous populations lack fundamental data needed to understand these events and effective countermeasures. This cross-case study sets a framework for exploring Indian Nations'... 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... 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... This study investigates geostatistical approaches using ordinary Kriging and clustering analysis for traffic crash data in order to identify the traffic accident hot spots in North Dakota counties. The research analyzes 37 years (1975–2011) of fatality crash data available from a U.S. National Highway... This document presents the application of the Highway Safety Manual (HSM) for rural local two-lane two-way highway segments in South Dakota. The calibration was based on three-year (2009-2011) crash data from 657 roadway segments constituting more than 750 miles of roadways. The calibration process includes... Traffic crashes stem from a variety of underlying causes. Too often, the cause is risky driving whether it is speeding, running a red light, or driving under the influence of drugs or alcohol. These risk factors have all been associated with increased risk of crashes. The goal of our work is to consider... In an attempt to predict these crashes, North Dakota driver licensing data and crash data were used to develop a sample of 20,392 teen drivers age 14 to 17. Within the first year after being licensed, these drivers sustained 317 crashes that resulted in an injury or death. The resulting logistic regression... North Dakota consistently experiences a relatively high level of crashes and injuries on rural roads, considering lane miles and vehicle miles traveled. Approximately 55% of the state's travel, in vehicle-miles, takes place on rural roads. North Dakota fatal crash reports from 2003 to 2007 show that... Each year there are more than 16,000 motor vehicle crashes (MVCs) on North Dakota roadways, resulting in more than 2,900 injuries and 107 fatalities. Understanding the economic impacts of these MVCs is important in discerning impacts of road investments, behaviors, and policy changes that affect public... |
