• Abstract:
  The effects of various police patrolling methods on the average speed and crash rate were studied in ; this report. The number of speeding citations under various enforcement strategies was also ; investigated. Two surveys were designed and conducted for this purpose, a pilot and a statewide ; study. The results show that speed enforcement had a statistically significant effect on reducing the ; average speed, which is more evident during the morning peak period. The average-speed analysis ; indicates the existence of time halo, as drivers maintain lower speeds for some period after ; enforcement stops. The minimum length of time halo was found to be at least 2 weeks. A ; methodology for the optimal allocation of enforcement resources is presented, along with ; recommendations for strategy selection and deployment.
