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...

This is an empirical study of food shopping trips in Seattle, Washington. In travel forecasting models, land use activities and transportation systems are assumed to be in static equilibrium. This paper deals with the dynamic nature of urban systems, specifically the interaction between food...

This paper deals with the process of change in urban systems, specifically the changes in the relationships between urban transportation and food retail distribution activities. The dynamic properties of food retailing and transportation systems are identified by tracing location patterns of...

Employment centers, residential locations, and home-to-work trips have traditionally been the focus of the urban transportation planning (UTP) process, while shopping and social/recreational trips have been largely neglected. This paper seeks to improve understanding of the relationships between...

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 report documents the current state of Intelligent Vehicle Highway Systems (IVHS) technologies in Europe with special attention to advanced traveler information systems (ATIS) and advanced traffic management systems (ATMS). The views presented in the report are largely derived from...

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...
