The focus of this project was to examine the potential travel, emissions, and consumer benefits of advanced freeway automation and travel demand management measures. The Sacramento Regional Travel Demand model (SACMET 95) was used to simulate the travel effects of travel demand management...

PATH AVCSS researches have been traditionally oriented toward automatic vehicle design. Recently, the field of investigation has been extended from Automated Highway System (AHS) to assistance driving systems. One of the tools built at PATH for automatic system design and assessment is SmartAHS....

This report details the PATH proving test results during the period of October 6 to December 1, 2000 on the test track of the Public Works Research Institute (PWRI) of the Ministry of Construction in Tsukuba City, Japan. This work is related to the "Attachment 5: System Evaluation by Proving...

We have enhanced and "tuned" SmartAHS and SHIFT to address a wide variety of functional and user needs. SmartAHS has become an important microsimulation tool for design, analysis and evaluation of AHS - and "pre-AHS" or AHS deployment - concepts and scenarios in dimensions of system performance...

We investigate the effect of a number of design alternatives on the safety and capacity of an Automated Highway System. Our methodology makes use of two computational tools, designed to highlight the fundamental limitations of the vehicle dynamics, sensing and control strategies and...

A comprehensive simulation capability is presented for the analysis of vehicular platoons with or without collisions. A separate collision module (CDM) is integrated within the Platoon Simulation Package (PSP) to allow the recognition and dynamic simulation of intra- platoon collisions. Test...

The objective of this paper is to design the network layer of a communication stack to be used in Automated Highway Systems (AHS). The communication model we propose allows cars to form private subnets, the configuration of which can change dynamically. Each car be part of multiple subnets and...

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...

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...
