FREEWAY INCIDENT MANAGEMENT IN THE SPOKANE AREA. FINAL REPORT

The Washington State Department of Transportation (WSDOT) has embarked on a Freeway and Arterial Management Effort (FAME). This effort includes the collection of data, assessment of incident-related impacts, and the generation of incident management strategies across the state. This report focuses its attention on the effectiveness of existing incident management strategies applicable to the Spokane I-90 urban section, from the Four Lakes Interchange (Exit 270) on the west to the Idaho State Line on the east, covering a length of 30 miles. With direction and assistance from a technical advisory committee data and information were gathered and analyzed to include roadway and accident characteristics of this urban section of I-90 and existing incident detection, response, servicing, and coordination practiced by several agencies serving the area. From this analysis, sections of I-90 that had a high potential for incidents were identified. As a result of this research, several useful products were developed, such as maps showing existing interchanges, detour routing for potential freeway closures, etc. Based on this preliminary analysis and evaluation it was evident that it would be necessary to carry this research forward to enhance the existing incident management methods practiced in the Spokane area. Five specific actions are recommended: (i) structure the database and, if necessary, identify and complete any missing data needed; (ii) prepare an incident management manual capable of being updated on a regular basis; (iii) form an incident management team; (iv) format the data/information for use in a knowledge-based expert system (KBES); and (v) adopt a KBES for Spokane.
