A traffic control center monitors the roads conditions via webcams scattered in different places in the city. Those cameras send the video stream of the road to the traffic control center via dedicated fiber optic cables network.
The traffic center informs the drivers of the vehicles about the roads status by sending short messages to “digital boards” in the road that has some problem (such as congestion, ice, fog, accident, road works …). Those digital boards are connected to the center through the fiber optic cables network.
A user at home with a computer and Internet connection can access the traffic control center web server (where live video streams from webcams is loaded into web pages) to check traffic congestion along a route before going out.
