Effects of Bottlenecks in Vehicle Traffic
نویسندگان
چکیده
Traffic congestion is usually observed at the upper streams of bottlenecks like tunnels. Congestion appears as stop-and-go waves and high density uniform flow. We perform simulations of traffic flow with a bottleneck using the coupled map optimal velocity model. The bottleneck is expressed as a road segment with speed reduction. The emergence of stop-andgo waves depends on the speed reduction in the bottleneck. A phenomenological theory of bottleneck effects is constructed.

Simulating the Effects of Type and Spacing of Traffic Calming Measures on Urban Road Capacity
One of the major reasons for accidents is speed. Top of Form Inappropriate speed has been identified as the most important causal factor for serious traffic accidents. Traffic calming measures (TCMs) are engineering measures that are widely implemented to improve road safety by considerably reducing vehicle speed. TCMs have been widely used in urban areas to reduce vehicle flow rat...
متن کاملEffect of Ad-Hoc Vehicular Network on Traffic Flow: Simulations in the Context of Three-Phase Traffic Theory
Effects of vehicle-to-vehicle (or/and vehicle-to-infrastructure communication, called also V2X communication) on traffic flow, which are relevant for ITS, are numerically studied. To make the study adequate with real measured traffic data, a testbed for wireless vehicle communication based on a microscopic model in the framework of threephase traffic theory is developed and discussed. In this t...
متن کاملAn Assessment of the Impact of Pedestrian Refuge Islands on Vehicle Speed Changes and Pedestrian Safety: Case Study in Tehran
Pedestrians are among the most vulnerable road users. Speed of vehicles is considered as one of the major causes of danger for pedestrians crossing the street. Therefore, it is of utmost importance to devise suitable solutions to reduce speed of vehicles. One of these solutions is installation of Pedestrian Refuge Islands (PRI) in very wide midblocks. With regard to fluctuations in pedestrian a...

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...
متن کاملA study of pedestrian-vehicle accidents in Iran in 2013
Background: In recent decades, ‎due to the increase in users of roads and inadequate attention to the creation and development of appropriate passageways for traffic, there has been a growing trend in traffic accidents and casualties caused by them. The traffic accidents among pedestrians to take necessary measures in a timely fashion should be well studied. This study was conducted with th...
