The U.S. Department of Transportation's Automated Guideway Transit Technology Program (AGTTP) is directed towards the development of critical technologies which provide the foundation for the successful deployment of Automated Guideway Transit (AGT) systems. The program is not directed towards development of complete deployable systems, but towards system elements which may be used in a variety of advanced urban transportation systems. As part of the AGTTP, a project was established to address two critical areas where technological improvements at the subsystem level can substantially improve the deployability of AGT systems: vehicle longitudinal control and reliability. One of the efforts discussed in this report deals with the longitudinal control aspects of automatic entrainment and platooning concepts. The project objectives were to: (1) develop functional and performance specifications for longitudinal control systems for AGT systems using automatic entrainment or platooning; (2) perform an analytical and experimental evaluation of an automatic coupling and decoupling system suitable for trained vehicle operation and failed vehicle pulling and pushing; (3) establish design concepts and specifications for automatic coupling systems which meet the requirements in a cost-effective manner; and (4) perform an analytical assessment of the platooning concept and establish platooned vehicle operation. Work in this report includes review of status of existing technology, specification of design goals and requirements, detailed mathematical modeling, analysis and simulation, development and specification of design concepts and their mechanization, and some experimental validation of the design. The latter will be reported in Volume 6 of the final report.
