Traffic situation determination systems, methods, and programs
First Claim
1. A traffic situation determination system, comprising:
- a vehicle;
a mobile phone communication network that estimates a travel path of the vehicle based on a mobile phone location signal received from the vehicle; and
an information center that communicates with a communication device of the vehicle and the mobile phone communication network; and
the vehicle including;
the communication device that communicates over the mobile phone communication network via a mobile phone communication signal; and
a controller that;
acquires a current position of the vehicle based on a radio signal received from a GPS satellite;
determines the travel path of the vehicle based on the acquired position of the vehicle;
determines whether a road on which the vehicle is traveling has a traffic jam;
if the road on which the vehicle is traveling has a traffic jam, causes the communication device to transmit information relating to the travel path to the information center; and
if the road on which the vehicle is traveling does not have a traffic jam, does not cause the communication device to transmit information relating to the travel path to the information center;
wherein the mobile phone location signal is a signal received by the mobile phone communication network to determine the location of the communication device and is different from the mobile phone communication signal, which is used to communicate data over the mobile phone communication network.

Abstract
Traffic situation determination systems, methods, and programs acquire a current position of the vehicle based on a radio signal received from a GPS satellite and determine a first travel path of the vehicle based on the acquired position of the vehicle. The systems, methods, and programs determine whether a road on which the vehicle is traveling has a traffic jam. If the road on which the vehicle is traveling has a traffic jam, the systems, methods and programs transmit first information relating to the first travel path from the vehicle to an information center. The systems, methods, and programs receive second information relating to a second travel path of the vehicle, the second information being received from a mobile phone communication center and being based on a mobile phone signal received by the mobile phone communication center. The systems, methods, and programs determine a road corresponding to the first travel path as having a traffic jam and determine a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam.

1. A traffic situation determination system, comprising:
-
a vehicle; a mobile phone communication network that estimates a travel path of the vehicle based on a mobile phone location signal received from the vehicle; and an information center that communicates with a communication device of the vehicle and the mobile phone communication network; and the vehicle including; the communication device that communicates over the mobile phone communication network via a mobile phone communication signal; and a controller that; acquires a current position of the vehicle based on a radio signal received from a GPS satellite; determines the travel path of the vehicle based on the acquired position of the vehicle; determines whether a road on which the vehicle is traveling has a traffic jam; if the road on which the vehicle is traveling has a traffic jam, causes the communication device to transmit information relating to the travel path to the information center; and if the road on which the vehicle is traveling does not have a traffic jam, does not cause the communication device to transmit information relating to the travel path to the information center; wherein the mobile phone location signal is a signal received by the mobile phone communication network to determine the location of the communication device and is different from the mobile phone communication signal, which is used to communicate data over the mobile phone communication network. - View Dependent Claims (2, 3, 4, 5, 6)

7. An information center, comprising:
-
a communication device that communicates with a mobile phone communication center and a vehicle; and a controller that; acquires from the communication device first information relating to a first travel path of the vehicle, the first information being received from the vehicle over a mobile phone communication network via a mobile phone communication signal and being based on a radio signal received from a GPS satellite; acquires from the communication device second information relating to a second travel path of the vehicle, the second information being received from the mobile phone communication center and having been estimated based on a mobile phone location signal received by the mobile phone communication center; determines a road corresponding to the first travel path as having a traffic jam; and determines a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam; wherein the mobile phone location signal is a signal received by the mobile phone communication center to determine the location of the vehicle and is different from the mobile phone communication signal, which is used to communicate data over the mobile phone communication network. - View Dependent Claims (8, 9, 10, 11)

12. A traffic situation determining method, comprising:
-
acquiring, with a vehicle controller, a current position of a vehicle based on a radio signal received from a GPS satellite; determining, with the vehicle controller, a first travel path of the vehicle based on the acquired position of the vehicle; determining, with the vehicle controller, whether a road on which the vehicle is traveling has a traffic jam; if the road on which the vehicle is traveling has a traffic jam, causing a communication device to transmit first information relating to the first travel path from the vehicle to an information center via a mobile phone communication signal communicated over a mobile phone communication network, the information center having an information center controller; receiving, with the information center controller, second information relating to a second travel path of the vehicle, the second information being received from a mobile phone communication center and having been estimated based on a mobile phone location signal received by the mobile phone communication center; determining, with the information center controller, a road corresponding to the first travel path as having a traffic jam; and determining, with the information center controller, a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam; wherein the mobile phone location signal is a signal received by the mobile phone communication center to determine the location of the vehicle and is different from the mobile phone communication signal, which is used to communicate data over the mobile phone communication network. - View Dependent Claims (13, 14, 15, 16)

17. A non-transitory computer-readable storage medium storing a computer-executable program usable to determine a traffic situation, the program comprising:
-
instructions for acquiring a current position of a vehicle based on a radio signal received from a GPS satellite; instructions for determining a first travel path of the vehicle based on the acquired position of the vehicle; instructions for determining whether a road on which the vehicle is traveling has a traffic jam; instructions for, if the road on which the vehicle is traveling has a traffic jam, transmitting first information relating to the first travel path from the vehicle to an information center via a mobile phone communication signal communicated over a mobile phone communication network; instructions for receiving second information relating to a second travel path of the vehicle, the second information being received from a mobile phone communication center and having been estimated based on a mobile phone location signal received by the mobile phone communication center; instructions for determining a road corresponding to the first travel path as having a traffic jam; and instructions for determining a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam; wherein the mobile phone location signal is a signal received by the mobile phone communication center to determine the location of the vehicle and is different from the mobile phone communication signal, which is used to communicate data over the mobile phone communication network.
