Abstract
To reliably avoid a dangerous zone by setting a route from a current position to a temporary destination so as to avoid the dangerous zone while reflecting prediction results of a moving direction even when a route setting is not previously made. A route to a temporary destination is set based on location information obtained and prediction results of a moving direction of a user, so that even when an avoidance scheduled route for avoiding a dangerous zone has not been decided in advance, the route from the current position to the temporary destination can be reliably set so as to avoid the dangerous zone, while reflecting the prediction results of the moving direction. As a result, safe and reliable route guidance while avoiding the dangerous zone can be executed.

13. A route guidance device for guiding a route to a moving operator, comprising:
-
an area information obtaining unit that obtains information on a zone to be avoided associated with map data; a location information obtaining unit that obtains location information of said operator or said route guidance device; an avoidance route setting unit that sets a route to a temporary destination while avoiding entering the zone to be avoided obtained by said area information obtaining unit;
based on said location information obtained by said location information obtaining unit and prediction results of a moving direction of said operator or said route guidance device, anda display signal generating unit that generates a display control signal for displaying the route to said temporary destination set by said avoidance route setting unit, wherein; said avoidance route setting unit includes; a moving direction predicting unit that predicts the moving direction of said operator or said route guidance device based on said location information obtained by said location information obtaining unit, a temporary destination setting unit that sets a temporary destination along the moving direction predicted by said moving direction predicting unit based on the information on the zone to be avoided obtained by said area information obtaining unit and said map data, and corrects said temporary destination thereafter in the case previously defined, a route determining unit that determines the route from a location concerning said location information to said temporary destination corrected after being set by said temporary destination setting unit based on said map data while avoiding the zone to be avoided obtained by said area information obtaining unit. - View Dependent Claims (14, 15, 16, 17)

18. A route guidance method for guiding a route to a moving operator, comprising:
-
an area information obtaining step for obtaining information on a zone to be avoided associated with map data; a location information obtaining step for obtaining location information of the operator or the route guidance device; an avoidance route setting step for setting a route to a tentative destination while avoiding entering the obtained zone to be avoided based on said obtained location information and prediction results of a moving direction of the operator or the route guidance device; and a display signal generating step for generating a display control signal for displaying the route to said set temporary destination, wherein; said avoidance route setting step includes; a moving direction prediction step for predicting a moving direction of said operator or said route guidance device based on said location information obtained by said location information obtaining step, a temporary destination setting step for setting said temporary destination along the moving direction predicted by said moving direction prediction step based on the information on the zone to be avoided obtained by said area information obtaining step and said map data, and correcting said temporary destination thereafter in the case previously defined, and a route determining step for determining a route from a location concerning said location information to said temporary destination corrected after being set by said temporary destination setting step based on said map data while avoiding the zone to be avoided obtained by said area information obtaining step. - View Dependent Claims (19)

20. A route guidance processing program for causing a calculating unit provided in the route guidance device to execute:
-
an area information obtaining step for obtaining information on a zone to be avoided associated with map data; a location information obtaining step for obtaining location information of an operator or the route guidance device; an avoidance route setting step for setting a route to a temporary destination while avoiding entering the obtained zone to be avoided based on said obtained location information and prediction results of a moving direction of said operator or said route guidance device; and a display signal generating step for generating a display control signal for displaying the route to said set temporary destination, wherein; said avoidance route setting step includes; a moving direction prediction step for predicting a moving direction of said operator or said route guidance device based on said location information obtained by said location information obtaining step, a temporary destination setting step for setting said temporary destination along said moving direction predicted by said moving direction prediction step based on the information on the zone to be avoided obtained by said area information obtaining step and said map data and correcting said temporary destination thereafter in the case previously defined, and a route determining step for determining a route from a location concerning said location information to said temporary destination corrected after being set by said temporary destination setting step based on said map data while avoiding the zone to be avoided obtained by said area information obtaining step. - View Dependent Claims (21)
