TravInfo is a Field Operational Test (FOT) sponsored by the U.S. Federal Highway Administration. The goal of the project is to implement a centralized traveler information center to collect, integrate, and broadly disseminate timely and accurate traveler information in the San Francisco Bay...

The Southern California Intelligent Transportation System (ITS) Priority Corridor (Priority Corridor) represented a unique opportunity for the region. During the course of this federally sponsored six-year program, the region was able to develop a set of cooperative plans and actions that...

Presents a sketch of a system architecture for the control and management tasks of an intelligent vehicle/highway system (IVHS)

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...

This project develops the environment for using the ATMIS simulation software developed under previous PATH projects (MOUs 39, 84, and 170) for real-time traffic simulation and scenario analysis with feedback from the real urban network. keywords: traffic simulation, databases, object-relation...

This project studied the feasibility of constructing an autonomous vehicle controller based on probabilistic inference and utility maximization. Several theoretical and algorithmic advances were required in order to create an inference system capable of handling vehicle monitoring in a real-time...

Acceptance of ITS components that are designed to increase capacity will hinge on the extent to which additional capacity induces additional travel. This study addressed methodologies for studying the effects of capacity on travel: 1) before and after studies or travel times and volumes in...

This bibliography, containing over 650 entries, is intended to serve as a guide to the major sources of information on highways. While sources listed focus primarily on the United States and Canada, some international materials have been included. Though emphasis is on current publications, some...

Final report for MOU 37 Automated Guidance of transit buses in urban areas will introduce challenges in terms of maintaining acceptable levels of service to patrons while not compromising system safety. In this report, we present the findings from conducting both an extensive literature review...

The objective of this study is to develop a methodology for incident duration prediction. The authors first developed an understanding of factors that influence incident duration. A series of truncated regression models is used to predict incident duration. The models account for the fact that...
