• Abstract:
  Louisiana's transportation system includes nearly 60,000 miles of roads, of which approximately 44,000 miles are under the jurisdiction of local authorities and the remainder are state controlled. Of the estimated annual average of 160,000 traffic crashes which occur on Louisiana's roads, about 40% occur on the local system including 23% of the total fatalities. Thus, the local road network is important to reaching Louisiana's short and long term goals for fatality and serious injury reduction. Local road agencies often lack the resources to adequately identify candidate locations for low cost safety improvements. They also often lack the means to estimate the cost of the safety improvements. This makes development of systematic improvement programs and investment decisions very difficult. Thus, the need exists to develop a method that allows identification of those locations in the local road network that are the most likely to experience high crash rates based on their traffic and geometric features, and to estimate the cost of those countermeasures that best address the safety problem.
