Abstract
As part of any program of speed management and enforcement, it is important to ensure that speed zoning is rational and consistent. Those responsible for zoning decisions are often faced with competing pressures and demands from particular interest groups. At the same time there is a lack of clear guidelines to the public and local authorities on what is an appropriate zone for particular conditions. This paper describes the development of a computer "advisor" program which can indicate the probable zoning decision a group of experts would make in a given situation.
