1. A travel assistance method, wherein, when a vehicle passes through a target section of a road after an information source in-vehicle device mounted in the vehicle has detected a significant event while the vehicle is traveling in the target section, the information source in-vehicle device transmits a captured image and additional information related to the significant event to a roadside device,
wherein when the roadside device does not receive, for a defined period of time, vehicle-traveling-data-recorder (VTDR) information indicating presence of a vehicle equipped with a VTDR and a device for delivering images, the roadside device starts detecting a significant event, and captures an image and additional information related to the significant event detected by the roadside device,
wherein when the roadside device receives the VTDR information, the roadside device stops detecting a significant event, and receives the captured image and additional information related to the significant event detected by the information source in-vehicle device,
wherein the roadside device transmits the captured image and additional information related to the significant event acquired from the roadside device or the information source in-vehicle device, directly or through a different roadside device to an information destination in-vehicle device mounted in a receiver vehicle which starts to travel in the target section, and
wherein the information destination in-vehicle device performs operations related to travel control based on the captured image and additional information related to the significant event.
