Integrated traffic conflict model for estimating crash modification factors.
Crash modification factors (CMFs) for road safety treatments are usually obtained through observational models based on reported crashes. Observational Bayesian before-and-after methods have been applied to obtain more precise estimates of CMFs by accounting for the regression-to-the-mean bias inherent in naive methods. However, sufficient crash data reported over an extended period of time are...
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 کاملDynamic Variable Speed Limit Strategies for Real-Time Crash Risk Reduction on Freeways
in the number and severity of shockwaves. The authors found that the implementation of variable speed limits provided calmer traffic and improved the distribution of the traffic over the available road space. In the United States, VSLs are used in Washington State, New Jersey, New Mexico, and Wisconsin to identify and implement a safe speed limit when inclement weather converges on vulnerable f...
متن کاملRural Community Knowledge of Stroke Warning Signs and Risk Factors
INTRODUCTION Rapid identification and treatment of ischemic stroke can lead to improved patient outcomes. Public education campaigns in selected communities have helped to increase knowledge about stroke, but most data represent large metropolitan centers working with academic institutions. Much less is known about knowledge of stroke among residents in rural communities. METHODS In 2004, 800...
متن کاملOverall impact of speed-related initiatives and factors on crash outcomes.
From December 2000 until July 2002 a package of speed-related initiatives and factors took place in Victoria, Australia. The broad aim of this study was to evaluate the overall impact of the package on crash outcomes. Monthly crash counts and injury severity proportions were assessed using Poisson and logistic regression models respectively. The model measured the overall effect of the package ...
