Indicator 5: Average clearance time for incidents lasting more than 90 minutes
Measure a: Average Clearance Time for Over-90-Minute Incidents
Description:
The Washington Department of Transportation and the Washington State Patrol are currently focusing on reducing the length of major incidents lasting more than 90 minutes, such as serious accidents involving fatalities and commercial motor vehicles. These incidents cause lengthy traffic backups and increase the likelihood of secondary collisions. Since 2005, average clearance time for major incidents lasting longer than 90 minutes has dropped. For example, in the first quarter of 2006, it took an average of 184 minutes to clear these major incidents; in the second quarter of 2008, average clearance time was reduced to 153 minutes.
