The Vehicle Lateral Control and Switching (VLACS) project has been established to investigate alternative steering and switching systems applicable to a wide variety of automated transit vehicle types. This project is part of the Automated Guideway Transit Technology (AGTT) development program derived from the Urban Mass Transportation Administration's experience with automated transportation systems. The objectives of the project are to: (1) reduce the cost, complexity and weight, and increase the life, reliability, maintainability, ride quality, and switching capability of VLACS systems; (2) develop specific performance requirements and guidelines for lateral control and switching systems for SLT, GRT, and PRT vehicles in trained and untrained configurations; (3) develop and evaluate baseline VLACS hardware designs reflecting project objectives; (4) provide experimental data to demonstrate capability of VLACS system and subsystem designs to meet performance requirements including line speed switching; (5) provide a comprehensive analytical evaluation of contact (mechanical) and non-contact (wire-follower) lateral guidance approaches; and (6) perform an assessment of the positive retention capabilities of automatic switching systems.
