The ISTEA/ITS Connection in California: The State of the Relationship and Opportunities for Productive and Beneficial Linkages

Miller, Mark
Jia, Wenyu
1998

This report describes research which had three objectives: 1) investigate the current state of California's implementation of the Intermodal Surface Transportation Efficiency Act (ISTEA) with respect to Intelligent Transportation Systems (ITS), 2) assess the extent to which ITS has been integrated within the State's transportation planning process, and 3) recommend opportunities for linkages between ISTEA and ITS that have not yet been recognized. A literature search was first conduced which studied the key features of ISTEA, specific ITS-related issues, the institutional environment, and...

This document contains the technical appendices to the report on Investigating Intelligent Transportation Systems Strategies on the Santa Monica Freeway Corridor (see PATH Database record no. 8800.)

The Impact of Intelligent Transportation Systems on Bus Driver Effectiveness

Bailey, Diane E.
Hall, Randolph
1997

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 in the automatic processing of information related to transferring passengers and in the increased speed with which emergency and maintenance calls can be handled.

Potential Payoffs from IVHS: A Framework for Analysis

Rockwell International Science Center
1992

The purpose of this study is to provide a logical framework for the identification and evaluation of alternative Intelligent Vehicle Highway Systems (IVHS) functions, to sort by importance, and to specifically relate the various IVHS functions with the public sector goals they might serve. Toward this goal, an analytical sensitivity study was performed to estimate the benefits of those functions associated with modifying the speed-density-flow curves through the application of vehicle automation. Some analysis was also carried out to assess intersection throughput when signalization is...

Testing a Proposed Decision-Oriented Framework to Understand its Deployment Issues: An Examination of the Travinfo Atis Project

Miller, Mark
1998

Deployment is at the forefront of current activity in California in the field of intelligent transportation systems. It is important to understand the multitude of issues associated with such deployment to increase the likelihood of a successful deployment initiative. A review and synthesis of the literature on deployment issues have been performed. This served as a basis for development of a proposed decision-oriented framework that may be used to recognize and organize issues for the deployment of intelligent transportation systems. The applicability of this framework to intelligent...

Field Evaluation of San Pablo Corridor Transit Signal Priority (TSP) System

Zhou, Kun

Sun, Sonja
Leung, Kai
Lau, James
Chiu, Paul
2008

This document reports the results of the evaluation of the Transit Signal Priority currently under operation at AC Transit. The paper discusses about the Measure of Effectiveness and a quantitative evaluation method for TSP. It reports the data collected and analysis conducted of the concerned TSP system and presented the evaluation results.

Evaluating the Impact of ITS on Personalized Public Transit

Dessouky, Maged M.
Aldaihani, Majid
Shah, Rutvij
2002

The focus of this project is to study alternative system architectures and ITS technologies that can improve the efficiency of personalized public transit and demand responsive systems such as paratransit. This report reviews available and emerging ITS technologies that have been deployed or are being considered for this industry. We also conducted a survey of commercially available computer aided dispatching software. We list the numerous features offered by these software packages. Also, included in this report is a statistical analysis of travel patterns of a paratransit provider in Los...

Bay Area ATIS Testbed Plan

Khattak, Asad
Al-Deek, Haitham
Yim, Youngbin
Hall, Randolf
1992

Several factors have motivated the development of Intelligent Vehicle Highway Systems (IVHS); among them are growing traffic congestion, concern for environmental degradation, the need to improve safety, and the desire to best utilize existing transportation infrastructure. Within the framework of M-IS, Advanced Traveler Information Systems (ATIS) will provide historical, real-time and predictive information to support travel decisions. ATIS offers significant benefits interms of improving the travel experience of individuals and enhancing system performance. In the long-term, ATIS may...

Institutional Aspects of Multi-Agency Transit Operations

Miller, Mark A.
Lam, Amy
2003

In this project we have investigated the institutional changes that have been undertaken recently by transit properties to work more closely - in partnership and coordination rather than in competition - with other regional public agencies (especially including other transit properties) to help address mutual transportation problems from a regional and less parochial perspective. Our investigation includes case studies both within and outside of California. From the case studies, both formal and informal mechanisms are used to forge strong regional coordination linkages. Several key...

Commercial Vehicle Operations in Intermodal Transportation Management Centers

Hall, R.
Intihar, C.
1997

The report documents findings from a series of studies investigating the role of commercial vehicle operations within inter-modal transportation management centers. The study concludes that there exists no strong market push to better integrate motor carrier operations with governmental agencies in California today. As companies adopt ITS technologies for vehicle tracking and wireless communication, they are clearly not pushing for electronic transfer of information to and from governmental agencies. Likewise, none of the companies in the vehicle tracking industry has given priority to...
