Speeding has been shown to increase the frequency and severity of collisions. Mobile photo radar enforcement (MPRE) programs aim to discourage speeding in order to reduce speed limit violations, and ultimately the frequency and severity of collisions. However, because enforcement resources are typically in short supply compared to the number of roadway facilities and locations in an urban area that could benefit from enforcement, a systematic management process can improve the effectiveness of a MPRE program. While there has been extensive research on how enforcement sites are chosen and how the impacts of MPRE are evaluated, significantly less attention has been given to the design of an integrated deployment, scheduling, and evaluation process specifically for MPRE. This paper presents a MPRE program design process, conceived in the context of the City of Edmonton’s MPRE program. The purpose of developing this program design is to provide planners and engineers with a systematic and analysis-based procedure to design and deploy a MPRE program. Potential MPRE locations are identified through a priority-based site selection process guided by speed violation and collision data from the City of Edmonton. MPRE operators follow a set of flexible guidelines for deploying to sites on a weekly basis. A schedule for program performance evaluation is proposed. Once operationalized, the MPRE program is expected to improve speed compliance by undermining drivers’ ability to predict the location and timing of MPRE, to ultimately reduce collisions and improve city-wide traffic safety.
