Safety Effectiveness Evaluation of Median Cable Barriers on Freeways in Ohio

项目名称：	Safety Effectiveness Evaluation of Median Cable Barriers on Freeways in Ohio
摘要：	The Ohio Department of Transportation (ODOT) began installing median cable barriers in 2003 along highway medians that are narrower than 59 ft. The aim of these barriers is to prevent cross-median crashes (CMC). These types of crashes occur when a vehicle leaves its travel way, enters or crosses the median dividing the highway directional lanes and collides with oncoming vehicles in the opposite direction. The goal of this student study is to evaluate safety effectiveness with respect to the reduction in the number of crashes, injury severities and fatalities, evaluate the impact of geometric features, traffic characteristics and environmental conditions to the safety performance of the cable barriers, and to develop crash modification factors (CMF) for median cable barriers specific for Ohio. Since cable barriers are much cheaper than the traditional concrete barriers, if found effective in their intended use, then they can become a preferred alternative in terms of reducing crash severity and cost.
