B.Tech student designs smart AI-powered traffic lights


We usually see that the traffic on the side of the road where we are driving is congested and that the opposite side is almost empty but the green signal is given for the same duration in all directions without assigning priority.

Caught in such an opportunity while traveling for a medical emergency, Deepraj Chowdhary, a B.Tech student from International Institute of Information Technology-Naya Raipur came up with the idea of ​​using artificial intelligence to speed up traffic smarter.

Dubbed the Smart Traffic Signal Management System for Roadways, Chowdhary used artificial intelligence in the Python programming language and written algorithms to give more green signals for the direction that has the highest density of vehicles. Currently, the waiting time for vehicles at traffic lights is evenly distributed regardless of density, although traffic police can adjust it manually. Additionally, almost all major traffic lights are hooked up to cameras that send live feed to the control room.

In an effort to test its new software, Chowdhury took a 20-minute video of U.S. road traffic and used it to test its smart signal system via an online simulation.

“It was very successful and we filed documents for a patent with the Indian government during the Covid pandemic last August. It takes between 8 and 10 months to get a patent,” he said.

Given the sensitivity, state governments do not allow any new traffic light development to be tested unless and until it is approved by the appropriate agency, said Chowdhury who was guided by members from the faculty, Maifuz Ali and Deepika Gupta. The same app can also have the technology to detect any emergency vehicles such as ambulances and firefighters in traffic and give them a priority signal.

In the event of an accident, the smart signal can send a direct alert to the nearest hospital and police station so that precious lives can be saved, he said. After receiving proper approval, Chowdhury plans to license the software package to start-ups for implementation not only in India but also overseas. The student has worked on numerous research projects integrating blockchain with artificial intelligence for network security.
