A Tool for Evaluating Demand Response Transit Accessibility

TL;DRAbstract

Demand Response Transit (DRT) is a critical form of transportation for handicapped, low income, and small/ medium sized communities. This type of service, which transports riders through an on-demand basis, is commonly used in communities that are not dense enough to support a fixed route transit system. Unfortunately, DRT systems face many challenges that restrict how well they can serve their community, including limited funding, understaffing, aging fleets, a lack of technical support, a lack of quantification of level of service standards, and minimal modeling/planning practices. This paper discusses a unique DRT accessibility tool that addresses these challenges by determining how well a DRT system serves its riders and the most efficient ways to improve this service. The DRT Accessibility Tool, which is developed in Microsoft Access based on DRT travel logs, service characteristics and surveys from Brownsville, Texas, uses a complex system of models to simulate actual daily DRT t
