Exploring Single Vehicle Crash Severity on Rural, Two-lane Highways with Crash-level and Occupant-level Multinomial Logit Models
This thesis is conducted to compare a crash-level severity model with an occupantlevel severity model for single-vehicle crashes on rural, two-lane roads. A multinomial logit model is used to identify and quantify the main contributing factors to the severity of rural, two-lane highway, single-vehicle crashes including human, roadway, and environmental factors. A comprehensive analysis of 5 yea...
متن کاملPotential crash reduction benefits of shoulder rumble strips in two-lane rural highways.
This paper reports the findings from a study aimed at examining the effectiveness of shoulder rumble strips in reducing run-off-the-road (ROR) crashes on two-lane rural highways using the empirical Bayes (EB) before-and-after analysis method. Specifically, the study analyzed the effects of traffic volume, roadway geometry and paved right shoulder width on the effectiveness of shoulder rumble st...
متن کاملCrash Prediction on Rural Roads
Historical data confirm that rural roadways carry less than half of America’s traffic but account for the majority of the nation’s vehicular deaths. According to NHTSA, Wyoming has the highest crash fatality rate in the nation with a reported 2009 road death rate of 24.6 per 100,000 population, more than twice the national average of 11.0. High speed two-lane rural roads are believed to contrib...
متن کاملFree-Gap Evaluation for Two-Lane Rural Highways
Transportation Research Record: Journal of the Transportation Research Board, No. 2223, Transportation Research Board of the National Academies, Washington, D.C., 2011, pp. 9–17. DOI: 10.3141/2223-02 Operating speed is most frequently represented by the 85th percentile speed (V85) of vehicles passing at a given road location, in a nonplatoon condition, and it is usually determined by spot speed...
متن کاملAlternative Design Consistency Rating Methods for Two-Lane Rural Highways
Design consistency refers to the conformance of a highway's geometry with driver expectancy. Drivers make fewer errors in the vicinity of geometric features that conform with their expectations. Techniques to evaluate the consistency of a design documented within this report include alignment indices, speed distribution measures, and driver workload. Alignment indices are quantitative measures ...
