Abstract:

Local road crash countermeasures are an important part of the overall eﬀ orts to reduce crashes and their severity in

Louisiana. The eﬀ orts to develop a local road safety program are hampered by the lack of an appropriate risk assessment

and low cost countermeasures that enable local agencies to reduce crash frequencies with limited budgets. This project

deals with both issues. First, statistical models were developed to assess the risk of local road segments with respect to

crash frequencies. Secondly, low cost countermeasures were researched and recommended for individual road segments

based on current geometric features, crash frequency, and type of crashes. Thirdly, a score was developed for each road

segment that incorporates the risk, beneﬁ ts of improvements, and cost, which allows ranking of road projects. Fourthly,

guidelines for a local road safety improvement program are provided to allow local agencies to develop procedures for a

systematic system-wide road improvement methodology.
