We in the business of administering the highway programs have been accused on numerous occasions of forgetting for whom we work, namely, the people who buy gas and supply the funds—the public. The collective “we” pertains primarily to the State Highway Com­ mission and the Bureau of Public Roads. We are the first to admit that we can do a better job in dealing with the public on highway transpo...

Reliable prediction of traffic loads is essential for bridge planning and design. In the study, an improved unbiased Grey Markov forecasting model is applied to predict traffic loads on highway bridges. The comparison between the predicted results and existing practical measurements indicates that high accuracy can be achieved by using the developed model for bridge load prediction. The develop...

This paper evaluates various options for addressing traffic problems on the Malahat highway corridor, north of Victoria, British Columbia. A combination of transit and vanpool service improvements, support strategies, and incremental roadway improvements is by far the most cost effective and beneficial option. Current planning tends to undervalue this approach by ignoring some costs of highway ...

In this project, we first planned to model a manufacturing system using a partial differential equation (PDE), since in the theory of traffic simulation and control, PDEs are used successfully for modeling the dynamic behavior of highway traffic. Because these traffic models show good correspondence with manufacturing systems (vehicles = products, highway = manufacturing system), PDEs can also ...

recent years have brought a great deal of expansion to the economic systems of developing countries. although they serve as vital link of economic activities, the transportation network of these countries have not grown proportionally. since transportation investments is a a substantial portion of the national budget, a good knowledge of each mode's various characteristics is essential, wh...

A highway system development involves huge irreversible investments, and requires rigorous modeling and analysis before the implementation decision is made. This decision-making process is embedded with multiple uncertainties due to changes in political, social, and environmental contexts. In this paper, we present a multistage stochastic model for decision making in highway development, operat...
