Abstract
A system for providing a vehicle with traffic information reflecting the real traffic condition in each traveling direction is provided, even if the vehicle travels in either branch direction in a branch point area including the branch point. A traffic information server collects information on the time required for traveling in the branch point area from an information providing vehicle and generates information on the time required for traveling in each traveling direction in the branch point area on the basis of the information. Upon receiving a request for providing the traffic information from a navigation system of a vehicle the traffic information server transmits the information on the time required for traveling in each traveling direction or the information on the time required for traveling on each route in the branch point area generated from the above information.
