The project reuses the sensor and actuator interface software developed by California PATH for the DEN1097 automated highway system demonstration on Highway I17 in San Diego during August 1997. This software is provided on the QNX operating system. It interfaces with the magnetometers, radars,...

In this report, the implementation in the SHIFT programming language of regulation layer control laws for the hierarchical California PATH Automated Highway System (AHS) is presented. The implemented regulation layer control laws are derived after the safe-feedback based maneuvers designed in...

The objectives of the project are: (1) to study the behavior of existing vehicle lateral control systems in the event of magnetometer failures, (2) to design controllers that use the output from only one set of magnetometers, and (3) to develop an autonomous lateral control scheme that uses no...

This report describes a combined steering and brake actuator system for use in automatic vehicle control research The system allows a standard passenger car to switch from normal manual operation to automatic operation and back in a seamless manner using largely standard parts. The system uses a...

The purpose of MOU-233 is to evaluate and test a low cost, short range radar sensor developed by Amerigon corporation through a subcontract with the University of Southern California. The radar is designed to be used as a ranging sensor for automatic vehicle following applications. It is...

This nal report describes the application of computer vision techniques to the lateral and longitudinal control of an autonomous highway vehicle. In the part of the project we focused on an analysis of the vehicle's lateral dynamics and the design of an appropriate controller for lateral control...

This paper extends earlier research on optimal lane assignment on an automated highway to dynamic networks. A path-based linear program is formulated and solved through a column generation method.

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...

Automatic vehicle following is an important feature of a fully or partially automated highway system (AHS). The on-board vehicle control system should be able to accept and process inputs from the driver, the infrastructure and other vehicles, perform diag- nostics and provide the appropriate...

The advance in research and development will make the deployment of automated vehicles a reality in the near future. The principal question is whether these technologies will lead to any benefits in terms of safety, capacity and traffic flow characteristics as they penetrate the current...
