Adding a fourth colour to traditional traffic lights could significantly reduce waiting times and thus make traffic flow better, benefiting all road users, whether they're riding in self-driving vehicles or not, according to a study. — AFP Relaxnews
For over a year, researchers at North Carolina State University have been working on a project that consists of using a new type of traffic light on signals at busy intersections in order to improve traffic flow. Initial simulations indicate that the new approach could prove beneficial for all kinds of road users.
