Emerging capabilities in computing, communications, and consumer electronics are joining forces to improve the quality of traveler information. The TRW TransCal Field Operational Test (FOT) will ultimately result in reduced travel time, decreased traffic congestion, and will improve safety and security in both rural and urban areas. TRW's TransCal test addresses two primary user needs: (1) en route advisory and traveler information services; and (2) emergency notification and personal security. TRW's TransCal partnership will also examine the public and private relationships necessary to move tested applications to full-scale deployment. The TransCal test will implement a comprehensive Inter-regional Traveler Information System (IRTIS) that integrates road, traffic, transit, weather, and value-added traveler services information from sources covering the entire geographic region between San Francisco and the Tahoe/Reno-Sparks area. Building on emerging Intelligent Transportation System (ITS) standards, the information system will disseminate information to and from travelers via telephone, personal digital assistants, in-vehicle navigation and display devices, and interactive kiosks, as well as through traditional broadcast media. Wireline and cellular telephone, and wireless FM subcarrier networks will be used to transmit information. The information system will be integrated with a satellite-based MayDay system to provide emergency notification with low-cost coverage at any location. MayDay can be automatically or manually triggered to alert the information system about emergencies.
