Smart Traffic Lights Signals

Abstract

Traditional traffic lights are very important in regulating traffic. However, traffic jam problems have not been completely solved. Therefore, there is a real need for using modern technologies to upgrade traditional traffic lights to be particularly smart. Our solution aims to upgrade normal traffic light to be smart traffic light; making traffic lights communicates with each other and letting an algorithm choose the state of each traffic light. By building an embedded system including a group of sensors, wireless communication component and microcontrollers, these devices will collect specific data and then send them to the system. System based on the implemented algorithm will decide which and when a traffic light will be green, and how many times will it do that. In addition, each traffic light communicates with the closest ones, by sending signals and data regarding the street traffic alerting the next traffic light of a possible crisis or emergency vehicles arriving. According to the number and the type of vehicles in each road. Building a multiple smart traffic light system such as the ones described above would offer an optimal usage of the traffic lights on roads. Also, would be beneficial to all stakeholders of this system, by not only saving human lives and their most valuable possession (their time) but also helping the environment, by reducing carbon emissions, all this will be achieved by reducing the time the car takes at traffic lights.
