ADVANCED DIAL-A-RIDE ALGORITHMS RESEARCH PROJECT

Abstract

The work builds upon the algorithms and the computer control procedures developed under the CARS Project between 1967 and 1971, and upon the findings of the Haddonfield, New Jersey, dial-a-ride demonstration project which ran from February, 1972 to October, 1974. The purpose of the Advanced Dial-A-Ride Algorithms Research (ADAR) Project was to develop advanced dial-a-ride control procedures based on the experience gained in Haddonfield, and to investigate the problem of controlling integrated dial-a-ride/fixed route services. Another demonstration project in Rochester, New York, began in April, 1975, which also provided significant input to the ADAR Project research. This document is structured so as to be readable by nontechnical persons not familiar with dial-a-ride algorithms research, as well as by more technical transportation planners. The first chapters contain background material --- what a control algorithm does, who it serves, and various general elements of algorithms planning. Later chapters describe the new work performed under the ADAR Project, and lessons learned from the demonstrations.
