Traffic and Safety Analysis Procedures: Final Report


This report summarizes a review of the procedures used by the Washington State Department of Transportation for manipulating, storing, and analyzing traffic and accident data. The study summarized in this report compared existing WSDOT procedures with those of other states and in the transportation literature. Recommendations were then made for refining the WSDOT procedures that will be included in the Department's new data storage and analysis system known as TRIPS (Transportation Information and Planning Support).
