We would like to thank Sonja Sun and Don Dean for their assistance and support. The assistance and feedback of Mathew Hardy of Mitretek has also been beneficial to the effort of this research and evaluation program. Also, this work would not have been possible without the cooperation of the transit agencies. (AC Transit) have contributed greatly during the technical visit to Europe and to this technical report. The authors would like to express their sincere appreciation to many people in the following companies who supplied information about their buses: • Gillig Corporation • New Flyer Industries • VanHool iv v Abstract Vehicle Assist and Automation (VAA) systems enable lane assist, precision docking and longitudinal control of transit vehicles. They offer the opportunities of providing high quality transit service within reduced lane widths. Transit vehicles in North America are mostly manufactured based on individual transit agencies' customized requirements. The interfaces between VAA components and the mechanical, electrical and electronic systems on the existing transit vehicle, if not defined properly, can be an impediment to large scale deployment of VAA technologies. This report summarizes a research effort in specifying the VAA interface requirements, with a goal to facilitate progress toward the development and deployment of VAA systems …
