| 摘要： | 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. |
