car accidents are documented as a growing public health problem in iran as well as other developing countries. generally growing number of population and vehicles are not accompanied by extending road construction programs. these could be result in high death, disability, and economic loss in such country compare to develop one. this mainly affected young person who are economically more active...

exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. these are incentives to reduce exhaust emissions to the barest minimum. two major cities in ghana, accra and kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...

Traditional traffic control systems based on traffic light have achieved a great success in reducing the average delay of vehicles or in improving the traffic capacity. The main idea of these systems is based on the optimization of the cycle time, the phase sequence, and the phase duration. The right-of-ways are assigned to vehicles of one or several movements for a specific time. With the emer...

One key technology of intelligent transportation systems is the use of advanced sensor systems for on-line surveillance to gather detailed information on traffic conditions. Traffic video analysis can provide a wide range of useful information to traffic planners. In this context, the object-level indexing of video data can enable vehicle classification, traffic flow analysis, incident detectio...

Traffic and Travel Information (TTI) systems in use today are based on a centralized structure. Sensors along the roadside monitor traffic density and transmit the results to a central unit where a situation analysis of the global traffic scenario is performed. The resulting traffic information is made available to the drivers via broadcast service or alternatively on demand via cellular phone....

Vehicle Color Recognition System is the implementation of automatic detection of predominant color of vehicles from the traffic images captured through CCTV cameras installed at crossings. This document presents a new effective method for extracting color of vehicle using MATLAB, Firstly vehicle is cropped automatically from the traffic image and then color of individual vehicle is picked accor...

Computer traffic simulation is important for making new traffic-control strategies. Microscopictraffic simulators can model traffic flow in a realistic manner and are ideal for agent-basedvehicle control. In this paper we describe a model of a reactive agent that is used to control asimulated vehicle. The agent is capable of tactical-level driving and has different driving styles.<l...

This work presents an algorithm for the optimization of urban traffic flow that computes the vehicle routes and traffic lights timing in real time. The optimization procedure uses a genetic algorithm whose fitness function consists of a high-level Petri net model of the urban traffic flow, which simulation results in the fitness value to be used. The outcome of this work is the optimization of ...

ITE JOURNAL / APRIL 2001 TRANSPORTATION PLANNERS often compare traffic to a fluid, assuming that a certain volume of vehicles must flow through the road system like water through a network of pipes. But in many situations urban traffic is more comparable to a gas, which expands to fill available space. Road improvements that reduce users’ travel costs tend to attract traffic from other routes, ...

One of the fundamental requirements to facilitate implementation of any Advanced Transportation Management and Information System (ATMIS) is the development of a real-time traffic surveillance system to produce reliable and accurate traffic performance measures. This study presents a new framework for anonymous vehicle tracking that is capable of tracing individual vehicles by utilizing vehicle...
