1. A traffic control system comprising:
a first vehicle control system, mounted on a first vehicle, configured to perform operations including:
determining a center position in a width direction of a traveling lane where the first vehicle travels using at least a sensor of the first vehicle;
performing traveling control to cause a deviation amount of the first vehicle in the width direction of the traveling lane from the center position to converge within a control range;
obtaining surrounding information of the first vehicle using at least one of a camera device and a radar device of the first vehicle, wherein the surrounding information includes a position in a lateral direction of the first vehicle with respect to the center position of the traveling lane; and
transmitting traveling information of the first vehicle and position information of a specific section of a road based on determining that the first vehicle travels the specific section, the specific section being each of sections where the first vehicle is controlled, based on the surrounding information, to deviate from the center position of the traveling lane when performing the traveling control so that the deviation amount exceeds the control range of the traveling control, the traveling information including information on the position in the lateral direction of the first vehicle in the specific section, information on a position of the specific section, and a passing time at which the vehicle passed the specific section, the traveling information not being transmitted when the first vehicle travels a traveling section other than the specific section;
a management and control system configured to perform operations including:
collecting the traveling information from the first vehicle control system and traveling information from a second vehicle control system configured to perform operations that are same as the operations to be performed by the first vehicle control system;
extracting information from the collected traveling information including the traveling information from the first vehicle control system and the traveling information from the second vehicle control system, by removing, in a case where a value corresponding to the position in the lateral direction of the first vehicle deviates from a predetermined value by a set value or more, the traveling information from the first vehicle control system from the collected traveling information;
based on the extracted information, generating recommended traveling information for the specific section, the recommended traveling information including a recommended route for vehicles to pass the specific section; and
transmitting the recommended traveling information, based on the position information of the specific section, to a third vehicle that is detected as a vehicle traveling the road toward the specific section; and
a third vehicle control system, mounted on the third vehicle, configured to perform operations that are same as the operations to be performed by the first and second vehicle control systems, and configured to perform operations including:
based on receiving the recommended traveling information from the management and control system, changing a target route of the third vehicle to the recommended route, and controlling the third vehicle to travel the specific section of the road along the recommended route; and
when not receiving the recommended traveling information from the management and control system, controlling the third vehicle to continue performing the traveling control to follow the target route of the third vehicle,
wherein the third vehicle control system is further configured to:
determine, based on receiving the recommended traveling information from the management and control system, whether an obstacle in the specific section prevents the third vehicle from maintaining the recommended route based on surrounding information of the third vehicle;
control the third vehicle to travel the specific section of the road along the recommended route further based on determining that no obstacle prevents the third vehicle from maintaining the recommended route; and
control the third vehicle to travel the specific section of the road along a new traveling route calculated based on surrounding information using at least one of the camera device and the radar device of the third vehicle when determining that the obstacle prevents the third vehicle from maintaining the recommended route.
