Traffic congestion is a major concern for many cities throughout the world. In a general traffic light controller, the traffic lights change at a constant cycle time. Hence it does not provide an optimal solution.Many traffic light controllers in current use are based on the “time-of-the-day” scheme, which use a limited number of predetermined traffic light patterns and implement these patterns...

background and aims: this study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in iran. methods: in a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light cr...

Congestions of the traffic flow within the urban traffic network have been a challenging task for all the urban developers. Many approaches have been introduced into the current system to solve the traffic congestion problems. Reconfiguration of the traffic signal timing plan has been carried out through implementation of different techniques. However, dynamic characteristics of the traffic flo...

Very light jets constitute a class of three to eight passenger turbofan-powered aircraft thatwill enter service in 2006 and will need to be integrated into the National Airspace System. An aircraft performance analysis showed similarities between the predicted performance and capabilities of very light jets and the performance of existing light jets. Based on this, an analysis of operating patt...

Intelligent traffic lights are critical cyber-physical systems that help smart cities to cut road congestion and vehicle emissions. However, they also open a new frontier of cybersecurity. Security researchers have demonstrated ways to compromise the traffic lights to cause potential traffic disruption and public safety degradation. This study aims to raise the public awareness of the cybersecu...

Very Light Jets (VLJs) constitute a class of three to eight passenger turbofan-powered aircraft that will enter service in 2006 and will need to be integrated into the National Airspace System. An aircraft performance analysis showed similarities between the predicted performance and capability of Very Light Jets and the performance of existing Light Jets. Based on this an analysis of operating...

Our objective is to define a basic scenario in order to understand various problems faced by traditional traffic light control system and to provide technical solution to amend these adversities to improve the speed of transport. Congestion due to vehicular traffic intersection at junction is one the major issues to be considered. To overcome such issues an intelligent traffic signal network is...

Introduction With the growth of modern cities and the reliance of many of their populations on personal automobiles for the primary mode of transport, finding improved means to control the flux of vehicles has grown increasingly important. There are substantial benefits to be derived from improved traffic flow. For many commuters, reclaiming part of their day would enhance their quality of life...

Traffic jams and suboptimal traffic flows are ubiquitous in our modern societies, and they create enormous economic losses each year. Delays at traffic lights alone contribute roughly 10 percent of all delays in US traffic. As most traffic light scheduling systems currently in use are static, set up by human experts rather than being adaptive, the interest in machine learning approaches to this...
