A mobile photo enforcement (MPE) program deploys enforcement resources (equipment and personnel) to roadway locations, using radar and license plate photos to “catch” speed-limit violators. Where and when to deploy MPE program resources is a very important part of MPE operations, which helps enforcement agencies emphasize their road safety improvement goals and helps increasing the efficiency of program resource use. However, the design of MPE programs has received little attention from researchers.

The allocation of MPE resources is a complex process. This complexity arises from the fact that the allocation of MPE resources is not stationary, but it requires moving those resources from one site to another. Therefore, when MPE program managers allocate operators and equipment to sites, they must simultaneously consider the location of the resource allocation, the time of the allocation, and the availability of resource. Due to this complexity, a tool that can assist MPE program managers in making an effective and efficient resource deployment plan becomes necessary.
