Abstract

This paper introduces a systematic, data-driven framework by which to operate a mobile photo radar enforcement (MPRE) program, consisting broadly of site choice, enforcement resource allocation and scheduling, and evaluation. The overall goal is provide a framework for operating an MPRE program that is well-defined and replicable, in order to improve efficiency in deploying finite enforcement resources and efficacy in improving traffic safety. To illustrate the process, the proposed program was applied to simulate a deployment plan for one month using data from the City of Edmonton. The results of program application were assessed against the results of the existing MPRE program in place in May 2014, using several candidate short-term evaluation measures. Based on the results, it is expected that with implementation of the proposed program, the City of Edmonton’s MPRE program may observe moderate to high improvements in travel distance efficiency and coverage of sites with safety issues. The promising test results do further indicate the need for a full-scale, real-life deployment of the proposed program. This proposed MPRE program design framework can provide planners, engineers, and law enforcement professionals with a systematic, analytic, and data-driven process by which to operate a MPRE program. Despite that the design framework was built in response to the needs of the City of Edmonton’s current MPRE program, its development was generalized for adaptation and adoption within any jurisdiction looking to begin a new program, or make improvements to an existing one, in their pursuit of greater traffic safety.

5. Conclusions and future steps

Systematic, data-driven procedures that guide deployment for mobile photo radar enforcement (MPRE) programs have received little attention in the literature, and this paper aims to address this gap. A new MPRE program procedure is proposed in order to improve the utilization of limited enforcement resources, increase efficiency and contact with problematic roadway locations, and ultimately, improve urban traffic safety. The proposed site selection, prioritization, enforcement scheduling, evaluation, and adjustment process is an evidence-based program design, incorporating updated program performance information and traffic and enforcement data to achieve well-defined goals. The proposed program seeks to generate MPRE deployment plans on a monthly basis, with evaluations performed monthly as well as long-term. First, roadway sites that are potential targets for MPRE attention are identified through a selection and prioritization process informed by speed limit violation and collision data. Then, information regarding MPRE program resource availability is used to determine which sites are to be enforced, and how much, on a month-to-month basis. Finally, the resulting site visits are distributed on a weekly basis, while observing some basic rules (i.e. sites may not be visited in sequential shifts, etc.). In keeping with the existing MPRE program cultures, program managers and enforcement personnel (operators) maintain autonomy in making decisions in every step of the process. This process and its results are evaluated on both a short-term and long-term basis. The monthly evaluation is to facilitate monthly site list and deployment instruction adjustments, consisting of deployment statistics and traffic data as changes to collisions cannot be evaluated on such a short timeframe. The long-term evaluation is for assessing changes in collisions and speeds, to in turn assess overall program efficacy in improving urban traffic safety, and inform larger program changes as needed.
