Benefit

Automated red light enforcement reduced the number of violations by 42 percent at 5 intersections in San Francisco, California.

Experience with automated red light running enforcement in San Francisco.


March 1999
San Francisco; California; United States


Summary Information

The purpose of this study was to evaluate automated enforcement at five intersections in San Francisco, California from 1996 to 1998. Cameras and inductive loop detectors were installed at each intersection at a cost of 30,000 dollars per intersection. The automated enforcement equipment installed at each intersection was owned by individual pilot program vendors who received 17.50 dollars for each 104.00 dollar citation paid.

RESULTS

In the first six months of the program the San Francisco Department of Parking and Traffic (DPT) reported a 42 percent reduction in the number of red light violations at intersections with automated enforcement. In a separate study conducted by the Insurance Institute for Highway Safety in Oxnard, California, a 42 percent reduction in red light violations was reported. In the Oxnard study, a number of intersections were not equipped with cameras and the reduced number of red light violations in these areas was attributed to a spill-over effect from adjacent deployment. Based on the pilot program results, approximately 30 additional locations were slated for automated enforcement in 1999.
