California Partners for Advanced Transportation Technology

This is the final report for the project entitled \Evaluation and Analysis of Automated Highway System Concepts and Architectures" in response to the contractual requirements of the Memorandum of Understanding MOU# 235, between the Partners of Advanced Transit and Highways (PATH) and the University of Southern California, administered at the University of Califor- nia at Berkeley. The purpose of this project was to select, evaluate and analyze a num- ber of promising Automated Highway System (AHS) operational concepts based on previous work. The evaluation and analysis includes headway dis- tributions for vehicle following and lane changing, capacity calculations and the modeling, analysis and control of the resulting traffic flow. The design, analysis and simulation parts of the project were performed at the Center of Advanced Transportation Technologies at the University of Southern Cali- fornia. The work performed under this project is presented in the form of five reports presented in part I, II, III, IV, and V of this final report. In addition to these reports oppy disks containing the \Inter Vehicle Spacing Software Tool" is included. Keywords: Automated Highway Systems, Vehicle Following, Vehicle Spac- ing, Highway Capacity, Highway Safety, Accident Avoidance, Collision Avoid- ance, Braking Scenarios, Brake Performance, Lane Changing, Merging, Macro- scopic Models, Tra c Flow, Hybrid Systems, Roadway Controller.
