Problems solved by technology

The main disadvantages of this type of representation are as follows: First, each user may have different standards for classifying road congestion. Slow down”; Secondly, the published congestion level is usually calculated based on the average speed of multiple vehicles, and each road releases a congestion level, but due to various reasons such as the driving route of each vehicle and the events encountered, Multiple vehicles driving on the same road may experience different levels of congestion, so publishing an average level of congestion is not accurate enough for some vehicles
First of all, in terms of image information collection, the traffic center collects images for all roads that can capture image information. The amount of data is large, which takes up a lot of system resources and reduces the system processing capacity. capture useful information
Secondly, in terms of image information release, for a certain road link, the image information released by the traffic center to all users is the same, and it cannot provide targeted services to each user, and the reference value of the image is not high enough

Embodiment approach 1

[0073]Next, Embodiment 1 of the present invention will be described with reference to the drawings.

[0074] The first part describes the composition of the traffic management service system including the traffic management server (traffic management service device) of the present invention.

[0075] figure 1 It is a configuration diagram of a traffic management service system including a traffic management server according to Embodiment 1 of the present invention. The traffic management service system includes a traffic management server 200, a vehicle 300 without a camera device, and a vehicle 400 with a camera device. Wherein, the vehicle 300 and the vehicle 400 usually appear in the form of multiple vehicles, and between each vehicle 300 without a camera device and the traffic management server 200, and between each vehicle 400 with a camera device and the traffic management server 200, all can be Two-way communication via the communication module.

[0076] First, the t...

Embodiment approach 2

[0128] Embodiment 2 of the present invention will be described below.

[0129] In Embodiment 1, the classification standard of driving route features is: different exit links entered after leaving the deviation link. The difference from Embodiment 1 is that in Embodiment 2, the classification standard of the travel route features is: different destinations of the travel route (ie, the end points of the travel route). The "destination" here specifically refers to the destination located on the deviation road link.

[0130] Specifically, there may be one or more points of interest (POI, Point of Interest) on a road link, and these points of interest may become the destinations of some vehicles. Such as Figure 15 As shown in Fig. 1, for a vehicle with a point of interest on the road link as its destination, the driving speed and individual congestion level on the road link may be different from other vehicles due to queuing near the destination and looking for parking spaces. ...

Embodiment approach 3

[0140] Embodiment 3 of the present invention will be described below.

[0141] In Embodiment 1 and Embodiment 2, when sending an image capture instruction (step S363), the image information request module 260 of the traffic management server 200 broadcasts and transmits the image capture instruction information to the vehicle 400B with a camera near the deviation road link. . That is to say, no matter what the driving route of the vehicle 400B with the camera device is, the image capture instruction information received by all the vehicles 400B with the camera device near the deviated link is the same.

[0142] Different from Embodiment 1 and Embodiment 2, in Embodiment 3, the estimated driving route of the vehicle 400B with the camera device has been uploaded and stored in the data storage module 220 of the traffic management server 200 in advance. Therefore, before sending the image capture instruction, the traffic management server 200 can judge in advance whether the driv...

Abstract

The invention provides a device and a method for traffic management service. The device comprises a data storage part, a jam grade analyzing part, a deviation analyzing part, an image information request part and an image information receiving part. The data storage part is used for storing driving information of vehicles. The jam grade analyzing part is used for calculating driving speed of vehicles on a road chain and calculating total average jam grade of the road chain and individual jam grade of vehicles by summing driving speed of vehicles passing the road chain in a specific period of time. The deviation analyzing part is used for comparing the total average jam grade with the individual jam grade of vehicles and determining the road chain as a deviated road chain when inconsistency between the individual jam grade of vehicles and the total average jam grade exceeds a set proportion. The image information request part is used for sending image shooting instructions to vehicles with cameras and / or road surveillance devices with cameras near the deviated road chain so as to perform image acquisition to the deviated road chain. The image information receiving part is used for receiving image information of the deviated road chain and storing the image information to the data storage part.

Description

technical field [0001] The invention relates to a traffic management service device and a traffic management service method, which can accurately collect and issue traffic image information in real time with a small amount of data. Background technique [0002] With the popularization of electronic maps and navigation systems, more and more people will refer to the real-time congestion traffic information of the road before traveling, and then make their own travel plans. [0003] At present, there are two main types of real-time congestion traffic information. The first category is to identify the road congestion level by text or color. For example: indicate whether the road is "congested", "delayed" or "smooth", or use red, yellow, green and other colors to indicate different levels of congestion on the map. The second category is to provide real-time photos or video information of the road. These image information can be collected through roadside monitoring cameras or...
