METHOD, APPARATUS AND COMPUTER PROGRAM FOR ESTIMATING DRIVER'S PERSONALITY OF ROUTE SELECTION
First Claim
1. A method for estimating a parameter of an evaluation function used for selecting a route from a departure point to an arrival point, the method comprising:
- acquiring, with a processing device, information concerning a departure point and an arrival point and information concerning a route from the departure point to the arrival point;
generating a plurality of basic routes on the basis of the acquired information concerning the departure point and the arrival point and the acquired information concerning the route from the departure point to the arrival point;
acquiring information concerning a route actually selected;
calculating a parameter of an evaluation function that yields the actually selected route as an optimum route among the plurality of basic routes and the actually selected route;
generating a new route using the calculated parameter;
determining whether or not the generated new route is identical to the actually selected route;
on a condition that it is determined that the generated new route is not identical to the actually selected route, adding the generated new route to the basic routes, calculating a parameter of the evaluation function anew, repeating generation of a new route, and comparing the generated new route with the actually selected route; and
on a condition that it is determined that the generated new route is identical to the actually selected route, storing the parameter at the time when the new data becomes identical to the actually selected route as a parameter of the evaluation function.

Abstract
A method for selecting a route from a departure point to an arrival point includes acquiring information concerning a departure point and an arrival point and information concerning a route from the departure point to the arrival point; generating a plurality of basic routes; calculating a parameter of an evaluation function that yields the selected route as an optimum route; generating a new route using the calculated parameter, determining whether or not the generated new route is identical to the selected route; on a condition that the generated new route is not identical to the selected route, adding the generated new route to the basic routes, recalculating the parameter, generating a new route, and comparing the new route with the selected route; and if the new route is identical to the selected route, storing the parameter when the new data becomes identical to the selected route.
