Smart Road-Lights and Auto Traffic-Signal Controller with Emergency Overide

تاریخ : دسمبر ۲۰۱۴ - اگست ۲۰۱۸

We proposed a scheme for smart road-lights and auto traffic-signal controller with emergency override, based on an Arduino microcontroller. It estimates the extent of the existing vehicular concentration using ultrasonic sensors, providing different time slots to each road based on traffic density. The proposed system attempts to reduce the probability of traffic jams caused by the unmanaged traffic lights. Another aim is to provide a hassle-free, pre-eminent clearance for the emergency vehicles. In order to do so, we designed a portable remote that uses Bluetooth modules to communicate with the signal controller. The controller responds to the arrival of any such vehicle and acts accordingly. The objective is to reduce the delay of emergency vehicles for reaching the scenes of disaster with minimum possible interruption to regular traffic flow. Moreover, this article aims to incorporate the design of the intelligent street lighting system to endorse the idea of “energy on demand”. Conventional street lights in areas with a low frequency of passers-by remain active most of the night without purpose, which is wasting power, consequently. To curb this problem, we advocate the use of Ultrasonic sensors to detect the motion of the automobiles or pedestrians, hence, activating lights when required with optimal energy consumption.
