In this paper, the authors propose an algorithm that increases and decreases the transmission speed according to a user-specified function. The design objective is to regulate baud as efficiently as possible and ensure that in each transmission interval, transmitter and receiver bauds are equal...

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 dissertation deals with the application of Advanced Traveler Information Systems (ATIS) in incident management. Using an idealized traffic corridor and deterministic queuing methods, conditions under which route guidance information is useful are identified. Benefits to traffic guided with...

A model of drivers' route choice behavior under advanced traveler information systems (ATIS) is developed based on data collected from learning experiments using interactive computer simulation. A neural network model is used as a convenient modeling technique in the analysis. Results indicated...

This report characterizes the statistical performance of the magnetic nails concept for estimating the positions of vehicles within their marked lanes. The report also presents a mathematical model for sensor noise due to the distortions of the earth field by regular patterns of ferrous...

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...

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 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...

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...
