A traffic information prediction system, including a traffic information
prediction apparatus, of the present invention comprises travel status
measuring means for measuring a travel status of a vehicle and
accumulating it as travel record information, and traffic information
predicting means for predicting traffic information on a route on the
basis of the travel record information and statistical traffic
information to predict an arrival time to any place on a route containing
the destination. The traffic information predicting means compares a
traveling trace based on the statistical traffic information and the
traveling trace based on the travel record information to calculate the
degree of progress of the travel record based on the statistical traffic
information, and correct the traveling trace based on the statistical
traffic information on the basis of the degree of progress.
