First Claim
Patent Images
1. A stop history data accumulation system comprising:
- a state information acquisition unit that obtains state information indicating a state of a vehicle;
a stop history acquisition unit that, based on the state information, obtains group information that is formed from first stop information, including a first stop position at which the vehicle stopped and information specifying a first signalized intersection nearest to the vehicle that is ahead of the vehicle at the first stop position, and formed from second stop information, including a second stop position at which the vehicle stopped subsequent to the first stop position and information specifying a second signalized intersection nearest to the vehicle that is ahead of the vehicle at the second stop position; and
a stop history accumulation unit that, based on the group information, accumulates identification information which is the information specifying the second signalized intersection, by associating with the first stop position and the information specifying the first signalized intersection, the identification information being used for identifying a road zone including the second stop position, whereinthe identification information is associated with a distance between the first stop position and the first signalized intersection.

Abstract
State information indicating an state of a vehicle is obtained. Based on the state information, group information is obtained that is formed from first stop information including a first stop position at which the vehicle stopped and formed from second stop information including a second stop position at which the vehicle stopped subsequent to the first stop position. Based on the group information, identification information for identifying a road zone including the second stop position is associated with the first stop position and accumulated.

7. A stop history data accumulation method comprising:
-
obtaining state information indicating a state of a vehicle; based on the state information, obtaining group information that is formed from first stop information, including a first stop position at which the vehicle stopped and information specifying a first signalized intersection nearest to the vehicle that is ahead of the vehicle at the first stop position, and formed from second stop information, including a second stop position at which the vehicle stopped subsequent to the first stop position and information specifying a second signalized intersection nearest to the vehicle that is ahead of the vehicle at the second stop position; and based on the group information, accumulating identification information which is the information specifying the second signalized intersection, by associating with the first stop position and the information specifying the first signalized intersection, the identification information being used for identifying a road zone including the second stop position, by associating with the first stop position, wherein the identification information is associated with a distance between the first stop position and the first signalized intersection.

8. A non-transitive computer-readable storage medium storing a computer-executable stop history data accumulation program that causes a computer to execute the functions of:
-
obtaining state information indicating a state of a vehicle; based on the state information, obtaining group information that is formed from first stop information, including a first stop position at which the vehicle stopped and information specifying a first signalized intersection nearest to the vehicle that is ahead of the vehicle at the first stop position, and formed from second stop information, including a second stop position at which the vehicle stopped subsequent to the first stop position and information specifying a second signalized intersection nearest to the vehicle that is ahead of the vehicle at the second stop position; and based on the group information, accumulating identification information which is the information specifying the second signalized intersection, by associating with the first stop position and the information specifying the first signalized intersection, the identification information being used for identifying a road zone including the second stop position, by associating with the first stop position, characterized in that the identification information is associated with a distance between the first stop position and the first signalized intersection.
