Problems solved by technology

In addition, in the technique described in Patent Document 3, the travel history of other vehicles is collected by inter-vehicle communication to analogize the traffic information on the road, but this does not have the effect of improving the accuracy of the traffic information obtained, and since only Because other vehicles within the communication range have to send and receive information, a large amount of unnecessary information sending and receiving and analysis processing occurs, and the processing load of the device that performs this processing increases

[0039] Below, refer to Figure 1 to Figure 11 A first embodiment of the present invention will be described. figure 2 schematically shows the system structure, figure 1 The electrical structure of the traffic information system is shown through a schematic block diagram, figure 2 A schematic diagram of a traffic information system is shown.

[0040] Such as figure 2 As shown, the traffic information system S is configured such that the information terminals 1 mounted on multiple vehicles such as vehicle A and vehicle B can communicate with the central device 20 through radio signals, whereby the information terminals 1, 1 capable of mutual information communication.

[0041] Such as figure 1 As shown, the information terminal 1 has a function as a vehicle navigation device mounted on vehicles A and B, and both vehicles A and B are equipped with the same navigation function.

[0042] Next, the navigation function of the vehicle A will be described. The information ter...

[0101] Figure 12 The second embodiment of the present invention is shown, which is different from the above-mentioned embodiment in that the captured image information is communicated between vehicles. The same reference numerals are assigned to the same or similar parts as those in the above-mentioned embodiment, and description thereof will be omitted, and different parts will be described below.

[0102] When the captured image information required for the specific vehicle A is transmitted and received via the center device 20 , the communication load on the center device 20 becomes high. Therefore, in this embodiment, if Figure 12 As shown, the captured image information is sent and received through vehicle-to-vehicle communication. Accordingly, the communication load of the center device 20 can be reduced. As the vehicle-to-vehicle communication not via the center device 20, it is preferable to perform the vehicle-to-vehicle communication when the vehicle A and the v...

[0106] Figure 13 The third embodiment of the present invention is shown, which differs from the above-mentioned embodiments in that when other mobile bodies pass through the section requiring imaging information, the captured image information is acquired after being permitted by the central device. The same reference numerals are assigned to the same or similar parts as those in the above-mentioned embodiment, and description thereof will be omitted, and different parts will be described below.

[0107] In the above-mentioned embodiment, if the center device 20 requests the information terminal 1 of another vehicle B to acquire the captured image information, the information terminal 1 of the vehicle B unconditionally acquires the captured image information. An embodiment in which the terminal 1 obtains the captured image information after obtaining permission from the center device 20 .

[0108] Figure 13 The processing procedure of the main part which changed in this em...

Abstract

PROBLEM TO BE SOLVED: To provide a traffic information system that allows a user to select and determine a route without requiring others for acquiring a captured image in a desired timing and location.SOLUTION: Before a vehicle A passes through a section where captured image information is required, a controller 21 of a center device 20 selects a vehicle B which has higher possibility of passing through the above section than a predetermined value, and issues a request to acquire captured image information to an information terminal 1 of the vehicle B (T6). The information terminal 1 of the vehicle B captures the outside of the vehicle B when passing through the section, and secures and stores the captured image information for an information terminal 1 of the vehicle A.

Description

technical field [0001] The present invention relates to a traffic information system, a traffic information acquiring device, and a traffic information providing device for providing detailed traffic information. Background technique [0002] Traffic information systems acquire information such as traffic conditions on roads using various methods, and play a role in various services such as traffic congestion relief (see, for example, Patent Documents 1 to 4). [0003] The technology described in Patent Document 1 provides a mobility support system that generates traffic information using information collected by VICS (Vehicle Information and Communication System) or probe cars, and provides traffic jam avoidance routes. Wait for more efficient movement. [0004] However, it is not possible to collect all the roads and provide high-precision real-time traffic information, and even when the traffic information of "traffic jam" is obtained, sometimes the traveler feels that t...
