IMPLEMENTATION AND OPERATION OF INTEGRATED TRANSIT SERVICES. SPEAKER 2

The major control functions (of considerable importance to integrated demand-responsive transportation (DRT) and conventional transit systems) are reviewed, and alternatives being implemented or are realistic possibilities for the future are presented. Control functions are composed of information transfer (related to service requests and vehicle activities), and decision-making (related to operation of DRT vehicles) functions. The service request option for the customer is the telephone system. For integrated systems, another option is receiving the request from the driver of a fixed-route bus (establishing direct communication between the control center and the driver of any route interfacing with DRT). Although the majority of DRT operations now use voice communication for driver instructions, digital communication will become the usual option for large integrated systems. In the Santa Clara integrated DRT and fixed-route system, digital communications will be used in conjunction with mobile displays and an automatic interfare with a computer used for dispatching. Information for driver progress form the driver to dispatcher may be digital or voice communication system. The decision process in integrated DRT and conventional systems can be divided into 3 functional categories: (1) control of simple DRT-the basic issues of a desirable control system are manual or automatic decision making, extent of future planning and commitment, and decentralization of decision making; (2) control of the conventional system; (3) control of transfer trips - the best issues for analyzing this function are (a) the extent of information pertinent to one subsystem, and (b) the extent of dependence of one subsystem on another.
