Filter by Keyword35 report(s) found with crashes in the keywords field 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... Trucks are a vital part of the logistics system in North Dakota. Recent energy developments have generated exponential growth in the demand for truck services. With increased density of trucks in the traffic mix, it is reasonable to expect some increase in the number of crashes. Analysis shows however... 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... 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... This report summarizes the work performed during the second phase of a two-phase research project. The first phase focused on two main areas: freight safety and wind vulnerability, and the identification of critical infrastructure. Phase I also tackled another major but less defined task in bringing... Motorcycle use brings increased risk to the operator simply by the nature of the vehicle. When a crash occurs, the threat of injury or death is magnified by physical exposure compared to that of other vehicle occupants. Detection and gap/speed judgments by other motorists present additional hazards to... 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... SAFETEA-LU contains language indicating that State Department of Transportation (DOTs) will be required to address safety on local and rural roads. It is important for state, county, and city officials to cooperate in producing a comprehensive safety plan to improve statewide safety. This legislation... The objective of this research is to investigate the injury severity of truck drivers by studying MV and SV accidents involving trucks on rural highways separately. By using multinomial logit models, the complex interactions between roadway characteristics, driver characteristics, accident characteristics... |
