Key elements of demand-responsive transportation (DRT) planning are discussed and common pitfalls are identified. Three fundamental items are necessary for the achievement of comprehensive DRT planning: (1) work statements which define the scope of each task to accomplish program objectives; (2) schedules of tasks laid out chronologically in logical sequence of events presented in the form of a bar chart or as a task interrelationship network; (3) budgets containing costs (or applications of funds) to accomplish the tasks - the status of each task is indicated by the relation of funds or person-hours expended to data versus those budgeted. For effective implementation control certain other key elements must be incorporated such as the arrangement of plans to fall into natural phases. Also, resources that must be considered include personnel, sources of funding, facilities and equipment, management, and intangibles such as political support. Contingency plans should be prepared for each element of the plan, and the program should be controlled on the basis of work accomplished, costs incurred, and schedule. Estimates of ridership are important in planning and a sector model has recently been developed. Recently developed supply models are outlined, and economic planning, the required level of technology, and operator selection and personel are briefly reviewed. Contingency planning must cover aspects such as legal issues arising from competition with other forms of transportation, modifications that must be made to standard equipment, the startup overload, radio license, critical paths in DR schedules (vehicles and radios), and the choosing of the mix of services (many-to-many, may-to-one, subscription, parcel delivery etc.).
