A concept-based introduction to paratransit is provided in this instructional module for undergraduate and graduate transportation-related courses for disciplines such as engineering, business, marketing, and technology. The concept of paratransit generally refers to modes of transportation other than mass transit and solo-driven automobiles. The characteristics and applications of various paratransit modes are examined. A systematic approach for paratransit planning is presented along with problems and issues associated with the design and implementation of paratransit systems. Additional topics include: factors associated with rural transportation systems and the potential of designing paratransit for rural areas; the concept of market segmentation analysis; measures of existing service efficiency; how simple efficiency indicators are calculated; how needs and services are compared to determine areas of unmet needs; the process of system design; financing and marketing paratransit operations; management tasks associated with paratransit; and the use of brokerage in paratransit management. Case histories, examples, and an eight-page bibliography are included. (SW)
