Because Intelligent Transportation Systems (ITS) R&D is performed for the ultimate deployment in the real world, deployment issues may limit design options for ITS concepts and technologies and, hence, can be viewed as constraints on ITS R&D. Therefore, ITS deployment issues must be studied at...

This report focuses on traffic congestion under current road conditions with the objective of developing a quantitative understanding of their costs. The work is intended to provide a foundation upon which to build later estimates of the benefits that could be attributable to the use of...

In this paper, the authors, although agreeing that deployment is the ultimate goal of Intelligent Transportation Systems (ITS) research and funding, believe that there is not sufficient knowledge of how, why and when to deploy specific ITS functions They contend that continued research and...

This paper proposes a shuttle van service as the initial deployment Automated Highway System (AHS) target. The freeway portion of the trip is fully automated and a professional driver is required for off-freeway driving. Advantages from the viewpoint of of different deployment issues are...

A study has been conducted to investigate current practices on decision-making under risk and uncertainty for infrastructure project investments. It was found that many European countries including Australia, the U.K., France, and Germany use scenarios for the investigation of the effects of...

Purpose: In this paper, the impact of Cooperative Adaptive Cruise Control (CACC) systems on traffic performance is examined using microscopic agent-based simulation. Using a developed traffic simulation model of a freeway with an on-ramp - created to induce perturbations and to trigger...

Purpose: An Intelligent Transportation System (ITS) must be able to predict traffic speed for short time intervals into the future along the branches between the many nodes in a traffic network in near real time using as few observed and stored speed values as possible. Such predictions support...

These last years, an increasingly significant number of traffic accidents caused by a malaise at the steering wheel was observed. The management of this kind of phenomenon is difficult and presents a real challenge. Given this fact, the authors try, in this paper, to propose a work which, thanks...
