<P>PROBLEM TO BE SOLVED: To more appropriately set representative travel time even when two peak values exist in probability density distribution of travel time of a road. <P>SOLUTION: When two peak values exist in probability density distribution with respect to travel time of an object road, the larger peak value of index values Jpk1, Jpk2 obtained by reflecting probability Ppk1, Ppk2 in a range belonging to the respective peak values and signal stop probability Pstp that a vehicle stops by a signal device on the object road is selected (S200-S260), and travel time of the selected peak value is set as representative travel time Ttrp (S270, S280). Thus, a situation that the representative travel time Ttrp deviates from travel time of an actual road is avoided, and the representative travel time Ttrp is more appropriately set in comparison with the case that an average value of the probability density distribution with respect to the travel time of the object road is set as the representative travel time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
