Navigation apparatus
View Patent ↗A navigation apparatus includes a map data acquiring means 11 a, 11, 12 , and 5 for acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified; a current position determining means 13, 14, 15, and 10 for determining a current position; and a route searching unit 130 for searching for a route from the current position determined by the current position determining means to a destination inputted by an input unit on the basis of the map data acquired by the map data acquiring means, and for, when a road where a car pool lane is also provided is included in a route acquired through the route search, presenting, as a recommended route, the route using the car pool lane if the distance over which the road will be traveled is equal to or longer than a predetermined value.
1. A navigation apparatus comprising:
a processor;
a processor-readable memory having stored therein instructions which, when executed by the processor, cause the processor to carry out steps of:
acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified;
determining a current position;
receiving, as input, a destination; and
searching for a route from the determined current position to the received destination on a basis of the acquired map data, and
when a road where a car pool lane is also provided is included in the searched-for route, presenting, as a recommended route, the route using said car pool lane when a distance over which said road will be traveled is equal to or longer than a predetermined value, while presenting, as the recommended route, the route without using said car pool lane when the distance over which said road will be traveled is shorter than the predetermined value.
2. The navigation apparatus according to claim 1 , the steps further including:
setting up information indicating use or nonuse of a car pool lane, as a route, according to a traveled distance, and
said presenting including presenting, as the recommended route, the route using said car pool lane in response to said setting up information indicating use of a car pool lane as a route when a distance over which said road will be traveled is equal to or longer than a predetermined value, while
presenting as the recommended route, the route without using said car pool lane when the distance over which said road will be traveled is shorter than the predetermined value.
3. The navigation apparatus according to claim 2 , the steps further including:
setting up a traveled distance for a road for which a car pool lane is also provided, and
said presenting including presenting, as the recommended route, the route using said car pool lane in response to said setting up information indicating use of a car pool lane as a route when a distance over which said road will be traveled is equal to or longer than the set up traveled distance, while
presenting, as the recommended route, the route without using said car pool lane when the distance over which said road will be traveled is shorter than the set up traveled distance.
4. The navigation apparatus according to claim 2 , the steps further including ignoring a result of said setting up information indicating use or nonuse of a car pool lane when a gate which is intended only for a car pool lane and in which a vehicle directly enters the car pool lane is included in the route.
5. A non-transitory computer-readable medium having stored therein instructions which, when executed by a processor, cause the processor to carry out steps of:
acquiring map data including data about roads for which whether or not a car pool lane is also provided is specified;
determining a current position;
receiving, as input, a destination; and
searching for a route from the determined current position to the received destination on a basis of the acquired map data, and
when a road where a car pool lane is also provided is included in the searched-for route, presenting, as a recommended route, the route using said car pool lane when a distance over which said road will be traveled is equal to or longer than a predetermined value, while presenting, as the recommended route, the route without using said car pool lane when the distance over which said road will be traveled is shorter than the predetermined value.
