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 work addresses two issues related to emergency maneuvers of autonomous vehicles. The first concerns the time-optimal speeds along specified path, which can be used to design emergency maneuvers. The second concerns the computation of optimal lane-change maneuvers for on- line collision...

In this study, the authors consider a family of six Automated Highway Systems (AHS) operational concepts. For each concept, the minimum inter- vehicle spacing that could be used for collision-free vehicle following, under different road conditions, is calculated. For architectures involving...

This paper considers the issue of safety in Automated Vehicle Highway Systems (AVHS). An approach is proposed for proving that a system is safe. The design for a proposed AVHS is considered and shown that if the physical controllers in the vehicles satisfy a set of constraints then the AVHS is...

This paper sets out a configuration for an Automated Highway System (AHS) which is believed to have advantages from a safety viewpoint. The configuration and operating principles are described. The scheme requires that vehicles change lanes directly from platoon to platoon, and that entry and...

This paper is concerned with the consequences of control system failures and external intrusions to a fully Automated Highway System (AHS). A model has been developed which enables the casualty rates in lines of automated vehicles to be calculated, following an initial event. It is applied to...

In this report, a comparison is drawn between the casualty rates per failure on an automated highway system (AHS) according to the longitudinal control configuration used. The comparison is drawn between closed-spaced platooning, vehicle following of the types used in Autonomous Intelligent...

This is the final and primary report of a PATH project which focused on developing and demonstrating methods by which the safety of Intelligent Vehicle Highway Systems (IVHS) can be assured, assessed and evaluated. Safety considerations were studied for automated freeways, driver aids, and copilots.

This report presents the executive summary to a study on developing and demonstrating methods by which the safety of Intelligent Vehicle Highway Systems (IVHS) can be assured, assessed and evaluated. Safety considerations were studied for automated freeways, driver aids and copilots. Management...
