摘要：	The Missouri Department of Transportation (MoDOT) currently uses an Exposure Index formula to prioritize its more than 4000 highway/rail crossings for safety upgrade. The E1 formula was developed in the 1970's and has not changed since then. This study evaluates the effectiveness of the EI formula and examines the possibility of adoption of an alternative formula for use in Missouri for prioritizing crossings for safety improvements. Seven models used by other states to prioritize rail-highway grade crossings were selected for study. A panel of officials associated with MoDOT, the U.S. Department of Transportation, and Railroad Companies was assembled to provide guidance to identify the most desirable models. Eight criteria, along with their relative importance, were identified to rank the models. After the models were analyzed and final indices developed, the panel of experts was assembled again to review and select a potential replacement model for the EI. The panel recommended the research team conduct sensitivity analyses on modifying the Kansas Design Hazard Rating model for possible use in Missouri. Subsequent analyses were inconclusive in determining potential modifications to the Kansas Model. However, it is our finding that consideration should be given to replacing EI with a form of the Kansas model and that further research be conducted on defining the necessary modifications to the Kansas Model.
