New 'smart traffic light' may reduce fleet time, air pollution 

Students at Shiv Nadar School here have developed an 'intelligent traffic light' system which they say may not only help reduce commute time but also lower air pollution. This makes the existing traffic light system responsive to real-time traffic intensity. It is the first system meant to work on Indian roads and will function accurately keeping in mind the traffic situation in the country, according to a project paper. Using a simple camera and a microcontroller,there have a way to calculate the amount of traffic present on the road using a camera and then modify the red/green distribution time at each junction dynamically.The system will cost only Rs 20,000 as compared to Rs eight lakh spent on other systems . Air pollution has a very negative impact on an individual's health and with the increasing vehicles; this problem is going to get worse. This reduction in time spent on the road will result in a decrease in the number of pollutants released by the cars and thus, reducing air pollution. The idea has also been applauded by the government at the recently concluded CSIR Innovation Award for School Children-2018, where the students bagged the fifth prize .
