 DRT systems require passengers to request a journey by booking with a central dispatcher who determines the journey options available given the users' location and destination.DRT systems take advantage of fleet telematics technology in the form of vehicle location systems, scheduling and dispatching software and hand-held/in vehicle computing.Vehicles used for DRT services will usually be small minibuses, reflecting the low ridership, but also allowing the service to provide as near a door to door service as practical, by being able to use residential streets.
