1. A vehicle travel assistance method in a no-lane section comprising:
a probe information storage step of storing probe information transmitted from a plurality of vehicles;
a matching processing step of extracting travel trajectory information of the vehicles in the no-lane section from the probe information stored in the probe information storage step and extracting vehicle travel trajectory information per combination of an entry point and an exit point for the no-lane section;
a statistical processing step of sorting the vehicle travel trajectory information per combination of the entry point and the exit point for the no-lane section extracted in the matching processing step into a plurality of categories according to a predetermined criterion and calculating statistical trajectory information by statistical processing of the travel trajectory information for each of the plurality of categories; and
a route information transmission step of transmitting the statistical trajectory information calculated in the statistical processing step to the plurality of vehicles as vehicle route information in the no-lane section;
wherein
in the statistical processing step, the vehicle travel trajectory information per combination of the entry point and the exit point for the no-lane section extracted in the matching processing step is sorted into the plurality of categories according to a plurality of criteria, and
the plurality of criteria include a vehicle wheelbase or a vehicle length, and a passage time required for a vehicle to pass through the no-lane section.
