This report presents a study in which Advanced Traveler Information Systems (ATIS) user benefits are estimated from a survey of commuting behavior undertaken in the San Francisco Bay Area in 1993. Both reported and stated response to unexpected congestion are used to determine the commuters who...

This report presents a study of the effectiveness of the transit telephone information system on trip behavior at Metropolitan Transit Authority ( MTA), from both the user's and the operator's perspective. The objectives of the experiment were: 1) to assess the perception of dynamic transit...

This report presents a study whose objective is to explore how people deal with unexpected congestion during the pre-trip stage and how they might respond to Advanced Traveler Information Systems (ATIS). Travelers' route, departure time and mode selection decisions were investigated through a...

This paper presents a simple prototype to demonstrate the key functions of PLANiTS (Planning and Analysis for Integration for Intelligent Transportation Systems). The prototype has a planning vector that allows users to enter and edit transportation actions, performance measures and...

The ITS Decision website has been developed for the user who is interested in learning about various Intelligent Transportation System (ITS) technologies. Two tools have been developed that will help those users who wish to address a specific problem, obtain information relating to their...

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...

This paper presents a functional description of PLANiTS (Planning and Analysis Integration for Intelligent Transportation Systems). The methodology consists of a process-based computer system that supports a series of mutually interdependent steps which progress toward developing and programming...

This paper discusses the integration of PLANiTS (Planning and Analysis Integration for Intelligent Transportation Systems) components. The integration is achieved by defining a structure for representing transportation improvement actions, performance measures and environment in terms of...

This study presents a framework for integrating planning and analysis in a computer supported environment that facilitates deliberation and consensus seeking. The planning process conducted with the aid of an intelligent facilitator benefits from on-line analysis capabilities that are integrated...

The specific objective of this study is to assess traveler behavior impacts of Advanced Traveler Information Systems (ATIS) technologies and the consequent system impacts at highway bottlenecks caused by incidents and recurring congestion. This research is based on earlier work regarding impacts...
