Future vehicles will not need road signsNovember 4, 2018
Future vehicles will not need road signs: they will communicate with each other and with elements of the road infrastructure using the vehicle-to-vehicle protocol (V2V).
Imagine an intersection without a traffic light, where autocomputers on the move determine in the best way who will drive first. Such an approach will save roads from traffic jams and significantly speed up traffic. – he said, – The Virtual Traffic Lights (VTL) technology developed in the USA allows even ordinary cars to get rid of traffic lights.
How it works:
– all cars broadcast their position, speed and direction using a special wireless protocol;
– VTL algorithm collects data from all machines and imposes them on digital terrain maps;
– at the entrance to the intersection, the algorithm assigns the lead car;
– the driving car slows down in front of the intersection, turns on the red light for its direction and the green light for the perpendicular one;
– after this, the algorithm assigns a new driving machine;
– everything repeats: those who stood, passing the intersection.
What are the advantages of this technology:
– No downtime at traffic lights, which allows you to optimize traffic.
– Modeling on the maps of Pittsburgh and Porto showed a reduction in typical travel time by 30-60%.
– Traffic is optimized even if only some of the machines support VTL technology.
– Does not require expensive sensors and technologies (lidars, etc.)
– Very few auto models support the wireless DSRC protocol (dedicated short-range communications) on which the system is built.
– Cyclists and pedestrians do not fit into the scheme. They are offered to track with the help of cameras and computer vision, or to give light weight to sensors (both options are so-so).
