A traffic control system having a number of detectors spaced along a roadway being monitored. The detectors are organized in groups, each group being interconnected to a different post. The posts include transmission and reception equipment for communicating with the detectors of that group. A transmission line system has a number of sections with a single section corresponding respectively to a single group of detectors. The sections of the transmission line system are also respectively coupled to the posts. The posts are also organized into groups, each group being interconnected to a control computer. All the control computers are connected to a central computer and an operating center. The various computers can be set to control the traffic in response to the information detected. Also, communications can be carried out, both in code and in clear, between the vehicles using the roadway and the computers or the operating center. |
