1. An autonomous driving assistance system, comprising:
- a processor programmed to;
obtain road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane;
specify, based on the road information, a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, when the vehicle travels with autonomous driving assistance;
if a branch point where a road branches is present ahead in the direction in which the vehicle is traveling, and a new lane added at the branch point becomes a route different from an existing lane at the branch point, specify a route along the existing lane as the planned route; and
execute the autonomous driving assistance for the vehicle according to the specified planned route.

Abstract
Autonomous driving assistance systems, methods, and programs obtain road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane. The systems, methods, and programs specify, based on the road information, a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, when the vehicle travels with autonomous driving assistance, and execute the autonomous driving assistance for the vehicle according to the specified planned route.

17. An autonomous driving assistance method, comprising the steps of:
-
obtaining road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane; specifying a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, based on the road information, when the vehicle travels with autonomous driving assistance; if a branch point where a road branches is present ahead in the direction in which the vehicle is traveling, and a new lane added at the branch point becomes a route different from an existing lane at the branch point, specifying a route along the existing lane as the planned route; and executing the autonomous driving assistance for the vehicle according to the specified planned route.

18. A computer-readable storage medium storing a computer-executable program that causes a computer to perform the following functions:
-
obtaining road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane; specifying, based on the road information, a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, when the vehicle travels with autonomous driving assistance; if a branch point where a road branches is present ahead in the direction in which the vehicle is traveling, and a new lane added at the branch point becomes a route different from an existing lane at the branch point, specifying a route along the existing lane as the planned route; and executing the autonomous driving assistance for the vehicle according to the specified planned route.
