Benefit Cost Analysis of Accelerated Incident Clearance (Final Report)

Summary Information

The South Carolina Department of Transportation sponsored a study to examine the current state of the incident management industry in the US by reviewing the available published literature and by launching a nationwide survey of multiple incident management agencies. The study also evaluated the specific impact of traffic incidents on motorists on South Carolina freeways by using traffic simulation and benefit-cost analysis.

South Carolina uses sensors (loop and radar) and traffic cameras to detect and verify the location of incidents. The benefit-cost analysis in the report considered the use of these technologies in the Greenville, Charleston, Columbia, York, and Florence areas.

Benefits

Traffic Sensors
  • The average benefit to cost ratio for use of sensors to detect incidents across all five sites was 6.54:1.
  • Sensitivity analysis revealed that the lowest benefit to cost ratio was 4.50:1 and the highest was 10.23:1.
Traffic Cameras
  • The average benefit to cost ratio for use of traffic cameras to detect incidents across all five sites was 12.47:1.
  • Sensitivity analysis revealed that the lowest benefit to cost ratio was 9.91:1 and the highest was 16.61:1.
