Recently, the IntelliDrive initiative has been proposed by the US Department of Transportation (USDOT) to enhance on-road safety and efficiency. In this study, we provide a mathematical framework which predicts the effect of such technologies on the efficiency of multilane highway systems prior to their real-life deployment. Our study shall encompass mixed traffic conditions in which a variety ...

H ighway congestion is a daily phenomenon in all large metropolitan areas and a source of frustration and anxiety for millions of commuters and truckers. Incidents—vehicle accidents and breakdowns that tie up highway traffic-are a major cause of urban highway congestion. Once a concern limited to downtown areas of major cities, congestion is now a metropolitan-wide problem in medium, as well as...

Open-access multilane highways have a significant share in the highway network of Pakistan and other developing countries Asia. These high access density, design inconsistency, operational characteristics that differentiate them from partially controlled-access highways. This study identified factors affecting mobility open-access based on road users’ perceptions as well field observations. An ...

Bridges are the most important components in expansive transportation networks. And bridge management systems (BMS) have been developed to help government agencies maintain the bridges in their districts. However, bridge management systems vary with the different bridge types and the different management requirements for each maintenance level. The multi-level framework of a set of bridge manag...

Traffic flow is an interesting many-particle phenomenon, with nonlinear interactions between the vehicles. This paper studies highway traffic and presents a general framework for traffic modelling as a stochastic hybrid system (with continuous and discrete dynamics and some interactions between its components). The freeway is considered as a network of components, each component modelling a dif...

For sixty years, engineers and planners have debated the freeway's role in the city. Engineers have tended to view freeways strictly in traffic service terms. Planners, on the other hand, have long viewed freeways not only as a means of TRB 2003 Annual Meeting CD-ROM Original paper submittal – not revised by author. facilitating automobile transportation but also as a tool for reshaping the cit...

Decision-makers have long speculated that building separate roads for trucks and passenger cars, or at least separating them on their own lanes would accomplish two major objectives: 1) they would make the roadways safer for passenger cars, and 2) roadways designed specifically for a select class of vehicles rather than for all vehicles might represent overall savings in construction costs. Thi...

This article presents a knowledge-based application to study and analyze traffic behavior on major roads, using as the main surveillance artefact a video camera mounted on a relatively high place with a significant image analysis field. The system described presents something new which is the combination of both traditional traffic monitoring systems, that is, monitoring to get information on d...
