This demonstration proposal is for a distributed traffic intersection traffic-light control called GreenWave. The solution couples camera sensors with a novel collaborative multiagent goaloriented control algorithm to outperform both conventional and theoretical approaches. The system is designed for real use, although simulated traffic data will be used for the demonstration.

Traffic lights have been existing for around 100 years. The first signals were installed for safety reasons for avoiding accident between opposed traffic flows at an intersection. Due to a continually increasing traffic, the traffic lights became a powerful tool for controlling the flows : the stake was to increase the intersection capacity and to decrease the congestion and the overall delay. ...

In this paper, a fuzzy logic control system was constructed for controlling the green time length for a real single intersection with multiple lanes, turns, and two pedestrian crossings. Control of pedestrian crossingd was achieved by assigning pedestrian crossingd into related light phases, which were controlled by a fuzzy logic controller. An evolutionary algorithm was employed to generate th...

The unnecessary long cross road waiting times for pedestrians is due to the inefficient traffic light system configuration and has led to the increasing number of traffic accidents involving pedestrians. This research designs, develops, constructs and tests the pedestrian monitoring approach to elevate the efficiency of traffic lights system configuration. This approach consists of two phases w...

When the degree of saturation at intersection approaches one, Webster’s optimum cycle length equation becomes inapplicable, because the cycle length will becomes very big when the degree of saturation approaches one and will be fully unrealistic when the degree of saturation becomes greater than one. This is not a problem for HCM2000 method. But optimum cycle length calculation in this method h...

We consider a single intersection of two two-way streets with controllable traffic lights on each corner. We construct a model that describes the evolution of the queue lengths in each lane as a function of time, and we discuss how (sub)optimal traffic light switching schemes for this system can be determined.

In 2007, the National Highway Traffic Safety Administration (NHTSA) reported that 8,650 people were killed as a result of intersection-related crashes.1 A high propor...

This work deals with the consequences of traffic light control strategies in signalized intersections on the behavior of users, particularly in terms of risk. Traffic light control consists in adapting traffic lights to the variable demand of traffic in order to improve the fluidity and the safety. An adaptive real-time control strategy developed at INRETS has been tested and gave good results ...

Traffic congestion becomes a serious issue nowadays especially at urban cities area. When road users come at the intersection point, there is always a conflict “who can go first” on their mind. Due to the high volume of vehicles on the road, intersection points need a traffic signaling device to control the traffic flow. That is the reason traffic signalling device is installed at most of the i...
