Automated Guideway Transit (AGT) systems are a potential means of providing convenient, dependable, cost-effective urban transportation. Prior to deployment, technical obstacles in the areas of network operation, vehicle control, safety, reliability, and maintainability must be resolved. The Urban Mass Transportation Administration (UMTA) has established the Automated Guideway Transit Technology Program to overcome these obstacles. Since the longitudinal control system encompasses most of the essential vehicle subsystems, it plays a critical role in the guideway operation. The VLCR project addresses those areas where technological improvements at the subsystem level can substantially improve the deployability of AGT systems. This report describes the activities performed in developing single-thread longitudinal control system designs which permit short-headway operation. The study relates to current systems which operate at headways greater than 20 seconds using fixed-block protection as well as systems which operate at headways in the 5-second regime, using moving-block protection. Conclusions and recommendations are included in this report.
