TravInfo is a Field Operational Test (FOT) sponsored by the U.S. Federal Highway Administration. The goal of the project is to implement a centralized traveler information center to collect, integrate, and broadly disseminate timely and accurate traveler information in the San Francisco Bay...

This report models response times and delays for highway incidents, according for spacing between interchanges and the time penalty for changing directions, enabling a response vehicle to reach an incident on the opposite side of the highway. A fundamental question in dispatching incident crews...

This working paper examines the process for managing incidents on highways, as it is applied in Los Angeles County. The examination is based on interviews with various agencies, including law enforcement, state highway department, coroners office, and LA County MTA Freeway Service Patrol, along...

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...

INCISIM is a computer program that simulates the occurrence of highway incidents, the dispatching of emergency vehicles, and the traffic flow on the network. INCISIM can represent multiple types of emergency vehicles, include highway patrol cars, freeway service patrol trucks, tow trucks...

This report describes a simulation model developed to evaluate the impact of using Intelligent Transportation Systems (ITS), such as Global Positioning Systems (GPS) for bus tracking, on controlling buses in wide-area transit networks. Control strategies with ITS will be compared against those...

This paper discusses how traffic information is obtained and how the congestion of a major freeway affects travel behavior. Immediately following two congestion-causing major highway incidents south of San Francisco, telephone surveys were conducted of commuters who utilize the affected corridor...

This paper evaluates dispatching rules at timed transfer transit terminals. The evaluation focuses on total passenger delay and the number of passengers missing their connections. Analytical and simulation models are developed to evaluate the benefit of Intelligent Transportation Systems (ITS)...

This paper examines the potential for Intelligent Transportation Systems (ITS) to improve bus driver effectiveness. Analysis of data gathered reveals the unlikelihood of improvement of individual bus driver effectiveness measures. The authors determined that the most visible benefits were seen...
