Claim 0:
1. An information processing server comprising:
a target vehicle data acquisition unit configured to acquire target vehicle data having traveling conditions of target vehicles and position information of the target vehicles on a map;
an unstable behavior position recognition unit configured to recognize, based on the target vehicle data, an unstable behavior position on the map where at least one of the target vehicles exhibits unstable behavior;
an occurrence counting unit configured to measure an occurrence count of unstable behavior positions within a predetermined period in a mesh preset on the map;
a mesh enlarging unit configured to enlarge the mesh to include the unstable behavior positions within the predetermined period such that the occurrence count of the unstable behavior positions is equal to or larger than a first threshold;
a storage processor configured to store the mesh and the unstable behavior positions of the mesh in a storage database related each other;
a vehicle assistant unit configured to, when one of the target vehicles is traveling toward the mesh including the unstable behavior positions, provide vehicle assistance related to the unstable behavior positions in the mesh for the target vehicle, wherein
the vehicle assistant unit is configured to change a vehicle assistance content depending on a size of the mesh.
