The high pace rise in vehicle counts, traffic density, and security concerns, a potential system for traffic surveillance, vehicle monitoring and control has become an inevitable need to facilitate intelligent transportation system (ITS). Although, numerous approaches have been proposed for moving vehicle detection and tracking, still the optimization needs can’t be ignored. In this paper, a ro...

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...

Recent advancement in traffic surveillance systems has allowed for obtaining more detailed vehicular movement such as individual vehicle trajectory data. Understanding the characteristics of interactions between leading vehicle and following in the traffic flow stream is a backbone for designing and evaluating more sophisticated traffic and vehicle control strategies. This study proposes a meth...

This article presents the architecture of Junior, a robotic vehicle capable of navigating urban environments autonomously. In doing so, the vehicle is able to select its own routes, perceive and interact with other traffic, and execute various urban driving skills including lane changes, U-turns, parking, and merging into moving traffic. The vehicle successfully finished and won second place in...

With the decreasing price of video cameras and their increased deployment on roadway networks, traffic data collection through video imaging has grown in popularity. Numerous vehicle detection and tracking algorithms have been developed for video sensors. However, most existing algorithms function only within a narrow band of environmental conditions and occlusion-free scenarios. In this study,...

Heavy vehicles have substantial impact on traffic flow particularly during heavy traffic conditions. Large amount of heavy vehicle lane changing manoeuvres may increase the number of traffic accidents and therefore reduce the freeway safety. Improving road capacity and enhancing traffic safety on freeways has been the motivation to establish heavy vehicle lane restriction strategies to reduce t...

Background & Objectives: Considering the lack of adequate basic information on risk factors for road traffic injuries in Iran, a study was conducted to determine the association between potential risk factors and the incidence of injuries in motor vehicle drivers. Methods: We performed a population-based case-control study on Qazvin-Loshan road. Risk factors related to injury incidence were...

The vision of intelligent vehicles traveling in road networks has prompted numerous concepts to control future traffic flow, one of which is the in-vehicle actuation of traffic control signals. The key of this concept is using intelligent vehicles as actuators for traffic control systems, replacing the traditional road-side systems. Under this concept, we design and test a control system that c...

Traffic is increasing day by day because of the increasing in vehicle usage especially in urban areas. Congestion in traffic also increases with the increase of vehicle numbers. To regulate the flow of vehicles we are presently using traffic light controllers which has three signals . With the help of these signals we can regulate the vehicle's direction. Most of the controllers has some fixed ...

Driving simulators are often used in a type of experiments where the result may depend on traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. It is clear that the ability to use phones during driving depends on the amount of traffic, and that realistic experiments in driving simulators therefore must include surrounding traffic. This paper ...
