Transportation Management Centers (TMCs) are focal points for monitoring and operating traffic management systems. As new technologies are developed through research in Intelligent-Vehicle- Highway Systems (IVHS), these TMCs will assume increasingly more importance as command and control centers...

This research investigates methodologies for fusing and further processing real-time road traffic data collected by probe vehicles and induction loop detectors in order to obtain relevant traffic information that is essential for effective deployment of Advanced Traffic Management Information...

In this paper, the authors address the problem of traffic surveillance in an Advanced Transportation Management System. They propose a new approach for detecting and tracking vehicles in road traffic scenes that attains a level of accuracy and reliability which lies beyond currently available...

This report summarizes the need for (dedicated) radio spectrum for IVHS communication services. It concludes that, if efficient architectures can be developed, several MHz of spectrum will be needed for large-scale introduction of IVHS services. Compared to most other reported estimates of the...

The focus of this research effort is the study of driver behavior in the presence of real-time traffic condition information. The methodology adapted for this research involves three parts: development of a theoretical model for driver behavior under Advanced Traveler Information Systems (ATIS),...

This study investigates issues concerning the implementation and impacts of lateral guidance/control systems and the phased implementation of these systems in exclusive-access High Occupancy Vehicle (HOV) lanes. The study is divided into 5 volumes. The objectives of each volume are as follows:...

This report reviews the recent studies adopted in order to understand drivers' behavior, and in particular, behavior when influenced by an Advanced Traveler Information System (ATIS). Different approaches were used in these studies: field experiments, route choice surveys, interactive computer...
