There is a considerable interest in demand-scheduled bus systems (DSB) as a potential urban transportation mode. This system consists of buses running on city streets with routes adjusted to meet the demands of new riders as well as to serve the needs of passengers already in the bus. There are two objectives for this type of bus service 1) to maximize the level of service to the passengers and 2) to minimize the cost of operation and control of the bus system. The supply portion of the DSB system is described.
