GIS-Based Multiobjective Optimization Tool for Development of Migration Plan for Next-Generation Controllers

Decisions about upgrade of traffic signal equipment are often made relying on the experience of the senior traffic engineers. Analysis often bases on conventional techniques such as before-after analysis, pilot studies, etc. Factors considered are the deployment time of the system, new technology available, and the performance of the system in the area under purview. Previous research has not defined guidelines or methods for developing a plan for the system replacement decision on a large scale. In addition, previous projects have not considered space and time for deployment of new signal control equipment. This paper presents methodology and a tool for large-scale signal-controllers migration plan. Methodology bases on the functional requirements of the next generation signal-control system. A tool is developed in Geographic Information System (GIS) environment. Upgrade plan is defined on a zone level and bases on optimizing budget constraints, control benefits and spatial distribution of equipment replacement. The entire evaluation methodology for the migration plan was demonstrated on signal control system of Northern Region of Virginia Department of Transportation.
