METHODS FOR EVALUATION OF RAIL-HIGHWAY GRADE CROSSING IMPROVEMENTS
This report discusses the results of a staff study which was performed to identify appropriate methods for evaluating improvements at rail-highway grade crossings. Six statistical concepts were identified for meeting various evaluation needs. Three of the methods provide for summaries and graphical displays of data. The other three methods provide for statistical tests of significance in comparative studies. Data available during the performance of the study included National Grade Crossing Inventory and Accident data for the years 1975-1977. The methods in the report can be used to compare data for the 1975-77 years with the data for the 1978-80 years. (FHWA)
