A lane change maneuver is one of the many appropriate responses to an emergency situation. The design of an Emergency Lane Change (ELC) maneu- ver for a platoon of two vehicles is considered in this paper. In response to the presence of a stationary or a slowly moving obstacle in the lane or any...

This report summarizes wind tunnel experimental measurementson the aerodynamic interaction between members of misaligned platoons. Experiments are conducted at the University of Southern California's Dryden Wind Tunnel Facility. All experiments are made using 1/8 scale models of 1991 Chevy...

The goal of this project is to develop a user-friendly simulation program which will allow the study of platoon dynamics in both nominal and emergency scenarios. The report discusses the issues investigated during the second phase of the project, including the inclusion of a vehicle model with...

This report details the aerodynamic performance of individual members of 2, 3, and 4-vehicle platoons. The primary purpose of the tests described is to quantify the behavior of vehicle drag as a function of vehicle spacing.

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 paper describes a fault tree analysis of an automated freeway and how conformity to safety criteria can be demonstrated by fault tree analysis. The system is initially explained, followed by a discussion of hazard analysis, fault tree, and an analysis of the results. Readers are advised to...

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...

This report presents a linear analysis of a tractor semitrailer model. The analysis is followed by the design of a simple linear controller for lane following. Offtracking analysis is presented for a single unit vehicle and tractor semitrailer. This analysis is independent of the control design....

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...

This report studies performance issues in Automated Vehicle Control Systems (AVCS). Specifically, it addresses the automatic braking controller design issues, effects of braking on Intelligent Vehicle Highway Systems (IVHS) lane capacity, performance of platoons with various information...
