Cumulation of urbanisation in India hasmade the automobiles much affordable than past, resulting in elevated trafficand congestion in major parts of the country. According to a recent study, anaverage Indian spends bare minimum of 90 minutes a day to commute from his/herplace of stay to the place of their work. The major cause for this can beattributed to the congestions at the peak places of a city. We present asustainable, robust and technological solution to reduce the congestion andthus helping commuters spend as less time as possible.We propose a module consisting of Ultrasonic vehicle detector, able tocount number of vehicles passing by a road before reaching the nextintersection.
The data from the detector is transmitted real time to thecontrol unit room. Based on the number of vehicles reaching a particularjunction, the traffic lights are controlled dynamically. With this system, thenumber of vehicles reaching a particular junction is known beforehand. If aparticular road in a junction is expected to receive more vehicles than others,the roads extending from that road will get a green signal, thus reducingcongestion.
Ultrasonic sensorsgenerate distance data by measuring the time taken to receive reflectedultrasonic waves. The time is directly proportional to the distance between theultrasonic sensor and the detection object. The efficiency of the ultrasonicsensor used in the vehicle detector is found to be 97% 1. Such ultrasonic vehicle detectors are to be installed at every junctionof the city so as to maximise the efficiency and the accuracy of the entiresystem. Control room for this traffic management system receives data from allover the city, processes it and sends real time signals to each traffic lightsystem.
This entire moduleimprovises the existing traffic control units’ efficiency in managing trafficbounds and leaps which otherwise work under a loop of fixed time interval,without considering the real time traffic data.
