1. A traffic control method executed by a receiver that is mounted in a vehicle moving on an arbitrary route, and can receive a plurality of types of traffic having different priorities,
wherein the receiver is configured to
include an arithmetic device, a storage device connected to the arithmetic device, and a network interface connected to the arithmetic device, and
manage an operation profile that stores data in which a section that is a part of the route and a communication quality in the section are associated,
wherein a first traffic and a second traffic having a lower priority than the first traffic can be received,
wherein the traffic control method comprises:
determining, by the receiver referring the operation profile, the section having a good communication quality to a transmission section in which the second traffic can be transmitted;
executing a traffic restriction determination process in which the receiver generates control information for controlling transmission of the second traffic,
wherein the traffic restriction determination process includes generating, by the receiver, first control information for controlling transmission of the second traffic not to hinder transmission of the first traffic when the vehicle is located in the transmission section,
wherein the data stored in the operation profile includes time as information for designating the section, and
wherein the traffic restriction determination process includes generating, by the receiver, second control information for controlling not to transmit the second traffic when the vehicle is located in a section other than the transmission section; and
transmitting the first control information and the second control information to a transmitter transmitting the second traffic.
