This is the final report for the project entitled "Evaluation of the Effects of Intelligent Cruise Control Vehicles in Mixed Traffic". The project was initially under MOU392 and switched to Task Order 4217 at the beginning of the 2nd year of the project. Due to this administrative change a final...

In this project, we design two new Adaptive Cruise Control (ACC) systems based on driver comfort, safety, vehicle following performance, environmental and traffic flow characteristics considerations. A new variable time headway rule is proposed and used to meet these considerations. Analysis and...

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 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...

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...

The use of advanced technologies and intelligence in vehicles and infrastructure could make the current highway transportation system much more efficient. Semi-automated vehicles with the capability of automatically following a vehicle in front as long as it is in the same lane and in the...

In this project we investigate the effect of heavy-duty trucks, equipped with different Adaptive Cruise Control (ACC) systems, on the environment and traffic flow characteristics. The sluggish dynamics of trucks whether manual or ACC that is due to their limited acceleration capabilities filter...
