Research Reports Filter by Keyword73 report(s) found with highways in the keywords field The trucking industry continues to contribute significantly to the economy of the United States. The surface transportation system has been a critical component for the movement of goods and services by the trucking industry across the country. Recent decades have seen substantial growth in freight miles... 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... Local rural road travel has the highest injury crash incidence in North Dakota. Crashes on these roads were determined to differ in contributing factors and characteristics when compared to those on other rural roads. Crash data from 2006 to 2010 was studied to quantify factor magnitude in predicting... The main objective of rural roadway pricing is revenue generation, rather than elimination of congestion externalities. This report presents a model that provides optimum tolls accounting for pavement deterioration and economic impacts. This model contains multiple components, because imposing tolls... 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... Seat belt use on rural roads is especially important due to the relatively high risk for injury compared to urban areas. In the northern plains, where nearly 90% of travel occurs on rural roads, addressing this issue is particularly critical. A cohort group of 32 states was used to study seat belt use... An attempt is made to integrally evaluate the safety of large trucks on mountainous highways. The I-70 corridor in Colorado is chosen to demonstrate the methodology because of its typical mountainous terrain and adverse weather conditions. First, the ten-year historical accident records are analyzed... 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... Given the sparsely distributed crashes across various highway systems, this study designed an empirical Bayes (EB) based sliding window technique within a spatial context. By examining roadway safety spatially, the safety analysts are able to account for high-risk locations completely within longer predefined... North Dakota county road managers were surveyed regarding safety practices, training, and resources. Responses establish a benchmark for understanding common practices and opportunities to promote safety on this high risk road system. Results show a range of activity with regard to county adaptation...
