This paper extends previous research on Computer Integrated Transportation (CIT) to commercial vehicle operations (CVO), specifically to examine how government can work with trucking companies within a CIT framework. The research entailed a review of how government currently interacts with trucking companies, interviews with trucking terminal managers, and case-studies on terminal operations at five of the nation's largest motor carriers. Opportunities are identified in the area of unifying interaction between government and industry and in the area of in- vehicle devices for automated record keeping.

This document focuses on a Field Operational Test (FOT) to develop an integrated information system for transit and traffic management and for traveler information that relies on Global Positioning System (GPS) equipped buses as probe vehicles. The document provides the evaluation plan for the FOT. The plan covers three principal elements: 1) Institutional, TMC Operator and Bus Operator, 2) Public Knowledge and Perceptions, and 3) System performance. The document provides an overall evaluation framework that describes how the evaluation elements will assess project objectives. In addition, for each element, the plan provides goals and objectives, data collection methods, data analysis methods, resources, schedule and deliverables.

This document is a users manual for DYN-OPT, a linear program that optimally and dynamically assigns traffic to lanes on an automated highway. The program maximizes the total flow across the highway over a pre-specified length of time. DYN-OPT solves a path-based formulation in which the highway is represented by discrete segments, time is divided into periods and traffic between origins and destinations follows a user- specified distribution.

This paper presents the preliminary findings of a first wave Broad Area survey, administered in November 1995, of the TravInfo Field Operation Test in the San Francisco Bay Area. The purpose of the survey was to define baseline attitudes, opinions and travel behavior of travelers for assessment of the general impact of TravInfo. Questions focused on trip characteristics, acquisition patterns of information, effects of traffic information on travel behavior and the demographic profiles of Bay Area travelers.

This study evaluates the performance and effectiveness of the Smart Traveler Advanced Traveler Information System (ATIS). The project is designed as a field operational test of three different media approaches for providing traveler information: fully automated telephone systems, automated multi-media touch screen kiosks, and PC via modem. The program is evaluated in terms of technical function, cost, user response and overall effectiveness.

This report presents the results of year two of the institutional evaluation of the TravInfo Field Operational Test (FOT). Numerous core participants and committee members were interviewed. The second year was dominated by TravInfo implementation issues, chief among which were: resolution of public/private controversies in the design of TravInfo and the attempt to ensure the completion of Caltrans' Traffic Operations System (TOS) for meeting the TravInfo schedule. Based on the interviews, the TravInfo organization is viewed at having been effective in resolving these issues.

TravInfo is a Field Operational Test (FOT) in advanced traveler information systems (ATIS) for the San Francisco Bay Area sponsored by the Federal Highway Administration (FHWA). The project involves a public/private partnership which seeks to compile, integrate and broadly disseminate timely and accurate multi-modal traveler information through commercial products and services. This working paper is part of the Technology Element of the TravInfo evaluation. It presents the results of the "before" wave of the Value-Added-Reseller (VAR) study, in which 17 TravInfo registered VARs and 16 non-registered VARs were interviewed. Interviews followed a semi-structured format, and covered the following issues: 1. Company profile; 2. Assessment of Current and Planned ATIS Products; 3. Assessment of the TravInfo Concept; 4. Perception of the ATIS Consumer Market and 5. Perception of TravInfo. From the interviews, it is clear that TravInfo has been effective in stimulating VAR business opportunities, that VARs support the project and intend to disseminate TravInfo information through their products. However, the future is uncertain. VAR participation will depend on their satisfaction with TravInfo's operations and data and on their perception of the size of the market for ATIS products and services.
