BEST PRACTICE:

I1−1: Interagency Agreement for Police Presence in Work Zones

DESCRIPTION:

The California Highway Patrol (CHP) has contracted with the California Department of Transportation (Caltrans) to provide services on an as−needed basis. The CHP, where appropriate, provides awareness of work zone areas and enforcement of the speed limit. The interagency agreement shares the responsibility between Caltrans and CHP for enhancing highway worker and motorist safety in and around highway work zones. Caltrans and CHP personnel work closely together to determine actions necessary to address highway worker and motorist safety, traffic control procedures, and anticipated traffic delays. Issues of collaboration can include methods of job site communication, traffic handling, acceptable traffic delays, contingency plans to address traffic mobility, and emergency vehicle routes. There are two parallel programs, the Construction Zone Enhanced Enforcement Program (COZEEP) and the Maintenance Zone Enhanced Enforcement Program (MAZEEP).

REASON(S) FOR ADOPTING:

Speed reduction and awareness of work zones was not being adequately accomplished through the use of signing, and channelizing devices, etc.

PRIMARY BENEFIT(S):

Reduction in highway and worker related accidents, creating an overall safer work zone.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

All types. All locations.

STATE(S) WHERE USED:
