In this paper, the authors study the capacity of key Automated Highway Systems (AHS) operating scenarios. The effect of the lane-flow rule, platooning or free-agent, as well as the lane barriers, on AHS capacity are studied. Special attention is paid to the interaction between the lane-flow rule...

The TravInfo project aims to develop a multi-modal traveler information system for the San Francisco Bay Area, developing a partnership between the public and private sectors. This report presents the results of the first wave of institutional interviews, as part of the TravInfo evaluation.

TravInfo is a field operation test in the San Francisco Bay Area, designed to implement a centralized traveler information center to collect, integrate, and disseminate timely and accurate traveler information. The evaluation of TravInfo consists of four elements: institutional, traveler...

This paper focuses on the role of standardization in managing and controlling an intelligent transportation system (ITS). The authors review activities and processes used by standards setting organizations. It is determined that standards address the needs for defining common interfaces for...

This report provides interim results on the design of interfaces between automated highways and conventional street systems. The purpose here is to identify the strategic issues in interface design, and to provide preliminary analysis on just one of these issues (separation between highway...

The objective of this report is to optimize performance of AutomatedHighway Systems through management of space accounting for interaction between entrance and exit processes. To accomplish this objective, we develop acomprehensive framework, including a new integrated highway model called the...

Intermodal transportation entails the coordinated movement of different types of transportation (rail, truck, automobile, etc.) to serve the needs of travelers and shippers. The purpose of this report is to provide a vision for systems to coordinate intermodal operations in California in the...

The main objectives of this study are to: 1) systematically classify new transit technologies and their impacts, 2) use the classification structure for exploring availability of new transit technologies, and 3) introduce technology developers to the California Advanced Public Transportation...

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...
