THE FREEWAY SERVICE PATROL EVALUATION PROJECT - DATABASE SUPPORT PROGRAMS, AND ACCESSIBILITY

This paper discusses the Freeway Service Patrol (FSP) Evaluation Proje ct conducted under the California PATH program. The goal of this proje ct was to determine the cost effectiveness of the FSP program along a 10-mile ''beat'' on I-880, near Hayward, California. We collected data from three different sources: loop detector data, probe vehicle data and incident log data. We describe these sources in detail and the pro blems that were encountered with them. We also discuss the support pro grams developed to process this data, and the efforts to place the dat a and the programs on-line for use by researchers around the country.
