APPLICATION OF GEOGRAPHIC INFORMATION SYSTEMS IN PLANNING TRANSIT SERVICES FOR PEOPLE WITH DISABILITIES

The scarcity of data on the travel patterns and needs of people with disabilities makes the planning of public transit system to meet the Americans with Disabilities Act and other requirements a difficult process. This means that approximate methods have to be employed under very broad assumptions to estimate demand, select routes, and schedule services. Even the common approximations such as catchment area method can be cumbersome when route density is high and service area is large. The application of a geographic information system (GIS) to perform the necessary computations is described. It is shown that information such as block group population and percentages of people with disabilities, which is available from census records, and general travel characteristics of people with disabilities can be combined to arrive at reasonable estimates of demand for transit services. The use of the GIS for scheduling demand-responsive services where fixed-route service is unavailable is also demonstrated.
