In this paper, we investigate congestion caused by differences in desired or possible speeds. Especially outside peak hours, speed differences are probably one of the most important reasons for congestion. Although the model setting, with one lane and no overtaking, may seem simple at first sight, the problem turns out to result easily in quite complicated mathematical expressions. Some main co...

The fast-growing market of autonomous vehicles, unmanned aerial and fleets in general necessitates the design smart automatic navigation systems considering stochastic latency along different paths traffic network. longstanding shortest path problem a deterministic network, whose counterpart congestion game setting is Wardrop equilibrium, has been studied extensively, but it well known that fin...

The idea of vehicle-highway communications sufficient to assume driving functions for the driver is not new. Researchers have articulated both its value and feasibility for several decades; and military and vehicle manufacturer test facility developments have proven the concept’s viability. As mounting congestion conflicts with environmental constraints, the Automated Highway System (AHS) promi...

This paper investigates the effects of congested freeway traffic conditions on motorists’ exposure to trafficrelated air pollution using real-world traffic data and a framework of established emissions and dispersion models. The intent is to isolate and compare the influences of congested traffic characteristics on exposure duration and exposure intensity. Mass inhalation of carbon monoxide (CO...

In this work, we propose an innovative adaptive recommendation mechanism for smart parking. The cognitive RF module will transmit the vehicle location information and the parking space requirements to the parking congestion computing center (PCCC) when the driver must find a parking space. Moreover, for the parking spaces, we use a cellular automata (CA) model mechanism that can adjust to full ...

total VKT (2). In developed countries, freight road transport continues to grow at a faster rate than the gross domestic product (3). This growth in commercial vehicle activity is increasing preexisting concerns over the associated negative externalities of urban freight movements. These externalities include greenhouse gases, air pollution, safety, and congestion and have been estimated to be ...

This report investigates the role that public transit can play in reducing traffic congestion. Investigates the role that public transit can play in reducing traffic congestion. This analysis indicates that high quality public transit tends to reduce congestion by attracting travelers who would otherwise drive. As public transit service improves on a corridor (including improved speed, convenie...

This paper studies the impacts of vehicular communications on efficiency of traffic in urban areas. We consider a Green Light Optimized Speed Advisory (GLOSA) application implementation in a typical reference area, and present the results of its performance analysis using an integrated cooperative ITS simulation platform. In addition, we study route alternation using Vehicle to Infrastructure (...
