TRAFFIC INFORMATION CREATING DEVICE, TRAFFIC INFORMATION CREATING METHOD AND PROGRAM
First Claim
1. A traffic information creating device comprising:
- a memory that stores map information including link information related to links that constitute a road; and
a controller that;
acquires a current location of a vehicle at unit time intervals;
acquires traffic information, which includes a distributed traffic congestion level of each link and which is distributed from a device outside the vehicle at predetermined time intervals;
each time the vehicle exits a link, sequentially stores the exited link in an exited link train on the basis of the map information;
determines whether the traffic information has been received; and
when it is determined that the traffic information has been received, stores the distributed traffic congestion level included in the received traffic information as a traffic congestion level in association with a portion of the exited link train within a range from the current location at a received time point at which the traffic information has been received to a location that is a predetermined distance behind the current location at the received time point in a travel direction among the exited link train.

Abstract
Devices, methods, and programs access map information including link information related to links that constitute a road, acquire a current location of a vehicle at unit time intervals, and acquire traffic information, which includes a distributed traffic congestion level of each link at predetermined time intervals. Each time the vehicle exits a link, the devices, methods, and programs sequentially store the exited link in an exited link train based on the map information. If the traffic information has been received, the devices, methods, and program store the distributed traffic congestion level included in the received traffic information as a traffic congestion level in association with a portion of the exited link train within a range from the current location at a received time point when the traffic information has been received to a location that is a predetermined distance behind the current location at the received time point.

5. A traffic information creating method comprising:
-
accessing stored map information including link information related to links that constitute a road; acquiring a current location of a vehicle at unit time intervals; acquiring traffic information, which includes a distributed traffic congestion level of each link and which is distributed from a device outside the vehicle at predetermined time intervals; each time the vehicle exits a link, sequentially storing the exited link in an exited link train on the basis of the map information; determining whether the traffic information has been received; and when it is determined that the traffic information has been received, storing the distributed traffic congestion level included in the received traffic information as a traffic congestion level in association with a portion of the exited link train within a range from the current location at a received time point at which the traffic information has been received to a location that is a predetermined distance behind the current location at the received time point in a travel direction among the exited link train. - View Dependent Claims (6, 7, 8)

9. A computer-readable storage device storing a computer-executable program usable to create traffic information, the program comprising:
-
instructions for accessing stored map information including link information related to links that constitute a road; instructions for acquiring a current location of a vehicle at unit time intervals; instructions for acquiring traffic information, which includes a distributed traffic congestion level of each link and which is distributed from a device outside the vehicle at predetermined time intervals; instructions for, each time the vehicle exits a link, sequentially storing the exited link in an exited link train on the basis of the map information; instructions for determining whether the traffic information has been received; and instructions for, when it is determined that the traffic information has been received, storing the distributed traffic congestion level included in the received traffic information as a traffic congestion level in association with a portion of the exited link train within a range from the current location at a received time point at which the traffic information has been received to a location that is a predetermined distance behind the current location at the received time point in a travel direction among the exited link train. - View Dependent Claims (10, 11, 12)
