VEHICLE GUIDANCE SYSTEM, VEHICLE GUIDANCE METHOD, MANAGEMENT DEVICE, AND CONTROL METHOD FOR SAME
First Claim
1. A vehicle guidance system that guides vehicles traveling on roads included in a road network, the vehicle guidance system comprising:
- a flow rate detection unit that detects a flow rate of vehicles on each of the roads included in the road network, and generating flow rate information representing a detection result;
a storage unit that stores the flow rate information of each of the roads generated by the flow rate detection unit in association with road identification information that identifies a road corresponding to the flow rate information;
a determination unit that specifies, as a candidate road, a road which vehicles enter from each of the roads included in the road network, acquires the flow rate information stored in the storage unit in association with the road identification information of the candidate road specified, and determines a rule regarding changing of the flow rate of vehicles on the candidate road based on the flow rate information acquired; and
a guidance unit that guides vehicles according to a determination result by the determination unit.

Abstract
This vehicle guidance system carries out guidance of vehicles that are traveling on roads making up a road network, the vehicle guidance system being provided with: a flow detection unit that detects the flow of vehicles on each of the roads making up a road network, and generates flow information indicating the detection result; a storage unit that creates associations between the flow information for the roads which has been generated by the flow detection unit, and road-identifying information indicating the corresponding roads, and storing the information; a decision unit that, for each of the roads making up the road network, specifies a candidate road that is a road which vehicles flow from the road in question, acquires the flow information that is stored in association with the road-identifying information indicating the specified candidate road in question, and based on the acquired flow information, decides on a flow increase or decrease policy of vehicles on the candidate road; and a guidance unit that carries out guidance of the vehicles, in accordance with the decision by the decision unit.

10. A method for controlling a management device which manages guiding of vehicles traveling on each of roads included in a road network, the method comprising:
-
acquiring flow rate information representing a detection result on a flow rate of vehicles on each of the roads included in the road network; storing the flow rate information of each road in association with road identification information that identifies a road corresponding to the flow rate information; and specifying, as a candidate road, a road which vehicles enter from each of the roads included in the road network, acquiring the stored flow rate information in association with the road identification information of the candidate road specified, determining a rule regarding changing of a flow rate of vehicles on the candidate road based on the flow rate information acquired and causing guidance unit that guides vehicles to guide the vehicles according to the determination result.
