Federica Garin, an automation engineer, shows how this system operates, as it is installed by Grenoble's Southern bypass road. There is a dual objective. First, the motorway traffic flow is measured with a network of sensors along the bypass road and second, traffic is regulated by using variable display road signs along this road. The collected data is used to produce algorithms to analyse and anticipate road traffic. This programme is a new step towards the smart and connected city of the future.
