TransGuide, San Antonio's Intelligent Transportation System (ITS), has been in operation since July of 1995. Initially covering 26 miles of freeways, TransGuide has expanded to cover more than 60 miles of freeways throughout San Antonio. The expanded coverage of freeway conditions in San Antonio has been coupled with arterial traffic data to provide traffic information on over 150 miles of the San Antonio area roadway network. The San Antonio Model Deployment Initiative (MDI) expanded TransGuide system capabilities, and brought together traffic information from multiple agencies. Since the conclusion of the Model Deployment Initiative, the Texas Department of Transportation (TxDOT) has implemented new programs to build upon that program's success. Expansion of the TransGuide system on heavily congested freeway corridors outside of downtown allowed the benefits of the system to be available to drivers who did not encounter the TransGuide system when it was located only in the downtown area of San Antonio. The development of the MDI Data Server combined information from TxDOT, the City of San Antonio and VIA Metropolitan Transit Authority to form a single depository of traffic related information available to all local public agencies and private sector Information Service Providers (ISPs).

The Tri-County Metropolitan Transportation District of Oregon (Tri-Met) has entered into an agreement with the City of Portland, Oregon to enable its transit buses to use the low Transit Priority request of the signals within the City’s jurisdiction. The three primary goals for the use of transit priority are: 1) to increase throughput within specified traffic corridors; 2) to reduce transit running times; and 3) to improve transit schedule reliability. This paper will focus on methods Tri-Met will employ to evaluate the effectiveness of its transit signal priority effort on transit operations, and to determine if its goals have been met. The project was scheduled to commence in February 2001, and preliminary evaluation results are expected by June 2001.

This paper describes the ongoing evaluation study of anonymous mobile call sampling for transportation applications underway in the Washington, D.C. metropolitan area. The Universities of Maryland and Virginia, with support from their respective State Departments of Transportation, are investigating the potential of the RadioCamera technology invented by U.S. Wireless Corporation to provide critical data for traffic management applications. This method of data collection is contrasted with other probe and point detection mechanisms. Descriptions of prototype transportation management applications employing this technology are offered. Potential technical limitations are described, as well as means by which they might be obviated. The planned economic evaluation is outlined, including the economic measures to be quantified, the range over which valuation will be conducted, and the means by which benefits will be enumerated. Finally, some conclusions are offered.

Traveler information is exchanged between public sector agencies, private companies, and private citizens. The World Wide Web is one of the most widely used dissemination mechanisms, along with voice telephony. Wireless Web access is rapidly growing. Most Web-based information exchange, however, can be classified as semi-automated. The information is primarily formatted for, presented to, and used by a human. The information is formatted for presentation using HyperText Markup Language (HTML). It is difficult to cost-effectively automate the processing of large amounts of HTML coded material, because the HTML doesn’t provide information about the meaning of the data, just how to present it. For this reason, the Web has not been a particularly attractive mechanism for fully-automated exchange between computer systems.

This paper describes the TripInfo proof-of-concept prototype. TripInfo has successfully demonstrated the applicability of XML to traveler information integration. TripInfo uses XML to integrate traveler information from multiple sources, and provide trip-based, rather than inkbased reports. The rational for the project, the project itself, and the lessons-learned are described.

This paper illustrates the use of a technology review as part of a regional ITS Architecture development. The paper identifies market and equipment packages that are available in the market but are not defined as part of the National ITS Architecture. These packages include Pedestrian Management and Information, Surface Street Control Enforcement, Joint-Use Vehicles, Parking Facility Enforcement/Security, Automated Parking Systems, Vehicle-Based Transit Information, Advanced Commercial Vehicle Safety Advisory, Emerging Probe Surveillance Technologies, and Speed Limit Enforcement/Dynamic Speed Limits.

The results presented in this paper indicates that a review of existing ITS technologies and products is useful in identifying market packages/equipment packages that meet specific regional, local and project needs.
