This report contains design and analysis results from UMTA's Vehicle Lateral Control and Switching (VLACS) Project of the Automated Guideway Transit Technology (AGTT) Program. The objective of the VLACS project is to develop lateral control and switching systems which will reduce the cost and improve the performance of these systems on automated transit vehicles. The VLACS project tasks include a review of existing lateral control and switching technology, detailed methematical modeling, analysis, simulation, detailed hardware studies, experimentation with alternative designs, and development of guideline specifications for VLACS systems. In this report, lateral control system models are developed for wire-follower, wall-follower active, and wall-follower passive lateral control systems, including the vehicle, lateral position sensors, and actuators. Vehicle dynamic models are developed for vehicles having Ackermann steering geometry and for vehicles with wagon-wheel steering. AGT vehicle models developed include ten-degree-of-freedom models used for ride quality analysis and simpler three-degree-of-freedom models used for lateral control system design and analysis. Part A of this report contains a description of VLACS model development.
