This study presents an initial step toward an understanding of consumer responses to advanced traveler information systems. Specifically, it is aimed at understanding the role that cellular telephones can play in the management of urban traffic systems. To assess the interrelationships between...

Current traffic travel time estimates are largely based on road sensors embedded in the pavement. Today technical developments in cellular positioning and the spread of wireless phones provide the opportunity to track cell phone equipped drivers as traffic probes. The Federal Communication...

This study focusses on the development of navigation and route guidance technologies with an emphasis on existing systems, industrial strategies, market approach and human factors considerations. By considering the different situations in the US, Europe, and Japan the report analyzes the...

This paper compares European and US experiences to explore critical institutional and organizational factors contributing to successful deployment of Intelligent Transportation Systems (ITS). ITS deployment has three primary aspects not found in traditional transportation solutions: 1) advanced...

Cellular probe technology is one of several potentially promising technologies for obtaining accurate travel time information. In 1996, the Federal Communications Commission (FCC) mandated E911 requirements that cellular location be provided when 911 emergency calls come in to emergency...

TravInfo TM is a regional traveler information system in the San Francisco Bay Area. It was a Field Operational Test (FOT) over a two-year period from September 1996 to September 1998 with funding from the Federal Highway Administration and the California Department of Transportation (Caltrans)....

This paper documents the final analysis of a three part series of institutional evaluations of the TravInfo Field Operational Test from its inception in 1992 through its completion in 1998. The Field Operational Test was performed over a two-year period from September 1996 to September 1998....

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 paper presents the design of an integrated smart feeder/shuttle system. The design of such a system was motivated by the need to provide easy access to main haul transit services. Park and ride lots in many train stations can no longer accommodate automobiles brought to the stations. Some...

Large urban areas often have rail systems that rely on feeder buses to expand their service area. This paper explores the possibility of expanding access to existing rail transit systems through demand-responsive shuttles. The study analyzes the effect of several factors on an individual's...
