Improving ADA Complementary Paratransit Demand Estimation

The objective of this research is to develop tools and an accompanying manual to improve ridership estimates for Americans with Disabilities Act (ADA) complementary paratransit services. The results of this research should assist public transportation systems in planning and providing services in the near and long term that meet paratransit requirements of the ADA. In keeping with the intent of the ADA law and regulations, the tool(s) developed by this project must be designed to predict demand for eligible trips. Although transit agencies may elect to provide service beyond that required by the ADA, the product of this project should be designed to predict only the demand required under law. For example, the tool(s) should consider only the population that travels within 3/4 of a mile of fixed routes. The tool(s) should consider only those persons who are truly eligible for service, and only those trips that these eligible individuals are unable to make by fixed-route service. Similarly, the tool(s) developed in this project must predict demand for complementary paratransit service that meets the level of service required. That is, the tool(s) must predict demand for service operated during the same hours as the fixed-route system and operated without capacity constraints. It is therefore important that when collecting data from transit systems to be used in the development of the tool(s), that the type and extent of service provided be considered. If information is used from a system that has a relatively "loose" eligibility process, for example, that will greatly affect the level of demand reported. If data are gathered from a system that has not eliminated capacity constraints, the level of demand will be understated.
