Incidents (vehicle accidents and disablements) significantly contribute to the growing traffic congestion problem in Washington state. To mitigate the adverse impacts of incidents, WSDOT has established a number of incident management systems that employ a variety of incident management procedures. Due to a lack of data, it has been difficult to quantify the effectiveness of these incident management systems. This study developed a database program to resolve this data deficiency. It provides a single, consistent, statewide incident management database. To develop the database program, extensive interviews with incident management personnel were conducted and a review of the extant literature was undertaken. With this information in hand, the incident management database program was developed and tested extensively in the field. The data entry program was developed using FoxPro, a relational database software for DOS-, Macintosh-, Unix-, or Windows-based computers. The resulting software package is easy to use or modify as needs evolve. Based on field tests of the database program, there is no doubt that its widespread use could eventually have a significant impact on the evaluation and development of incident management systems in Washington state.
