Centralized traffic algorithms to help drivers avoid congestion

Delivering sustainability in site visitors is not any simple feat. Might software program that globally coordinates vehicles to keep away from site visitors jams and congestion be the reply?

In 2019, drivers in Rome misplaced a mean of 166 hours to site visitors jams and congestion. In Paris it was 165, Dublin 154 and Athens 107. A 2016 report printed by the Swiss Federal Authorities confirmed that site visitors congestion value the nation CHF 1.6 billion yearly in misplaced time, wasted gas, environmental injury and accidents.

This 12 months, a gaggle of EPFL bachelor’s college students within the Faculty of Laptop and Communication Sciences undertook a venture to Make Clever Visitors as a part of the Making Clever Issues course. They used totally different centralized site visitors algorithms on teams of 3D printed Arduino vehicles to attempt to coordinate site visitors concurrently permitting customers to know the highway system and the place vehicles have been, in such a means that drivers might keep away from traffic jams and congestion.

“We wanted to build a traffic simulation that was more efficient than what we have right now in the world. We had a lot of ideas and in the end built a prototype in which cars didn’t speak directly with each other or determine their own locations but where a camera was directed at the area determining their location centrally by computer vision and sending that information to the cars,” mentioned Anirudhh Ramesh, a second-year IC bachelor’s scholar and staff member.

The staff constructed a highway community with crossings and streets which had a variety of various simulation modes. In a single the vehicles tried to succeed in a vacation spot that was randomly generated, in one other the vehicles wanted to choose up passengers like in a taxi service. The autos had small barcodes hooked up and the digicam detected and tracked these. The software program developed by the scholars predicted the place the vehicles ought to go, giving them directions and steering them in the proper path.

Small scale demonstration

Presently, autonomous automobile tasks are about particularly making one automobile in a position to efficiently navigate site visitors, keep away from harmful conditions and keep on the highway. They aren’t half of a bigger community equivalent to this and don’t talk with one another. “On a small, pilot scale this project demonstrated that centralized traffic algorithms were able to make decisions on where the cars should travel in a coordinated manner. It’s wonderful that these undergraduates came together with all their ideas and realized them in a very short time span,” mentioned Professor Christoph Koch, who teaches the course.

“Our main objective was to save people’s time and make traffic safer by making travel more efficient. In creating a system that’s more efficient we also hoped to save energy and fuel, making driving more sustainable in many ways,” Ramesh continued.

An actual problem

However the venture wasn’t all clean crusing. “Everything that you thought would be a challenge was a challenge! From coming up with a good design for the cars and backend, to getting the camera to detect all the cars and make the Bluetooth connect, there were a lot of loopholes we had to go through to get it to work. I think in the end, ironically, the computer vision things that we had to do were the easiest,” added Louis Dumas, a third-year bachelor’s student and in addition a staff member.

And the place may the scholars need to take this sturdy and profitable simulation venture? “We made our project open source and it would certainly be great to see this advance further, perhaps with future students from the course?” mentioned Dumas. “We have laid out a very strong foundation for hardware traffic simulations, and in doing so have learnt many invaluable skills. Maybe in the future we could have a satellite tv for pc system and the automobile industry might use our software program on their autos! However we all know that is a great distance off,” concluded Ramesh.
