Abstract:

In 1975, Rand made available two computer programs for analyzing deployment of police patrol cars the Patrol Car Allocation Model PCAM and the Hypercube Model. PCAM is used primarily to determine the total number of patrol cars a department needs and how they should be allocated over days of the week, hours of the day, and geography. The Hypercube Model is used primarily for designing patrol beats the areas covered by one car. Both of these models were specifically designed to serve the needs of local police agencies with little or no outside technical assistance. The documentation for each includes a nontechnical executive summary that explains the kinds of applications for which the model is suitable, a users manual that describes step-by-step how to operate the computer program once it is installed on a computer system, and a program description that provides information for data-processing personnel to install the model, construct a data base, and modify the model if needed. When the models were new, the designers undertook several field test in which they worked closely with police agencies to refine both the models and the methods of applying them. However, after publication of the documentation in 1975, Rand assistance to users has been limited. The designers have provided copies of the computer programs, fixed a few errors in the programs, responded to user inquiries, and provided advice to organizations that included the models in their training program.
