Infrastructure to vehicle communications using inductive loops

Road safety is a worldwide issue. The constant increase of the number of vehicles and the more congested infrastructure lead to more traffic incidents. Infrastructure to vehicle communication is a way to improve traffic safety, by sending traffic information to vehicles, such as the colour the next traffic light will be when the car reaches the road junction. This approach may be useful also for autonomous vehicles that need all the data available in order to travel in a safe manner on the road network. In this article we shall analyse the possibility of sending information from the traffic management system to vehicles using one of the most common traffic detectors, the inductive loop.
