• Abstract:
  The objectives of this study were to review and analyze the current procedures for identifying high-crash locations and evaluating and prioritizing roadway safety improvements at high-crash locations, and to recommend improved methods. Several tasks were undertaken to accomplish these objectives, including the following: ; • Review of program guidelines and procedures used by other states to prioritize improvements at high-crash locations ; • Review and documentation of Kentucky’s current procedures ; • Update of Kentucky’s Crash Buildup Program software to be compatible with the 2000 crash report form ; • Development of new software to assist in estimating the benefits and costs of potential projects for inclusion in the Hazard Elimination Program ; • Conversion of the dynamic programming software from mainframe to PC ; Results from the study include improved methods for identifying high-frequency crash locations and prioritizing those locations after preliminary analyses indicated a need to consider improvements at a crash site. Software was developed to produce a generalized estimate of the benefits and costs of potential projects for inclusion in the Hazard Elimination Program. Features included the following: 1) a menu of types of improvement projects and related reduction factors; 2) algorithms for calculating the present worth of annual benefits from crash reductions; and 3) benefit-cost comparisons for each project. The user must enter an estimate of project costs in order to estimate the benefit-cost ratio for the proposed improvement at a highway segment. ; Revisions were recommended for updating and enhancing the Crash Buildup Program to achieve compatibility with the current crash data report form and for translating the dynamic programming module from a mainframe operation to a PC-based system. It appears that an increased level of functionality has been achieved as a result of the series of modifications and improvements.
