Trucking productivity can be significantly increased by moving freight with longer combination vehicles (LCVs). However, LCV operations not only raise safety concerns for the surrounding traffic and the LCV drivers themselves but also can damage roadways and bridges not equipped to support the operations. All the discussion about truck size and weight limitations or about the pros and cons of LCV operations is predicated on the use of conventional tractors and trailers. We however observed that a root cause of several major issues associated with LCV operations is the problem of off-...

This report focuses on traffic congestion under current road conditions with the objective of developing a quantitative understanding of their costs. The work is intended to provide a foundation upon which to build later estimates of the benefits that could be attributable to the use of Intelligent Vehicle Highway Systems (IVHS) technologies. The report gives an overview of traffic congestion and summarizes the principal sources of research in the areas of quantifying the costs of congestion. It reviews this past work relative to the usage of data, methodological approaches used in the...

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) applications. The authors conclude that the benefit of ITS for timed transfer alone does not justify the implementation of Global Positioning Systems (GPS) for bus tracking technology.

This report attempts to derive a more accurate economic model to describe the supply and cost mechanisms that influence the market for traffic information. It first gives a history of the traffic information market, its economies-of-scale, and its potential for future development.e history of current The report discusses recent developments of value-added-resellers, the differences that exist in the marketing of their products, and factors influencing their success . Suggestions are presented for commercial broadcast stations and public agencies in terms of maximizing the total benefits of...
