A traffic control system includes a vehicle control system that transmits traveling information during traveling of a vehicle, and a management and control system that collects the traveling information from vehicle control systems of other vehicles and transmit recommended traveling information based on the collected traveling information. The vehicle control system transmits traveling data containing a traveling trajectory of the vehicle as the traveling information, and determines a third traveling route on which the vehicle travels, based on a first traveling route based on the recommended traveling information and a second traveling route based on a recognition result of a traveling environment of the vehicle. The management and control system collects the traveling data of vehicles traveling on a same travel lane and extract highly reliable data, and calculates the recommended traveling information based on the extracted traveling data and transmits the calculated recommended traveling information.
