Embodiment 1

[0040] Such as figure 1 As shown, this embodiment provides a method for judging and interpolating abnormal traffic data. This embodiment uses this method as an example to illustrate the application of the server. It can be understood that this method can also be applied to terminals, and can also be applied to It includes terminals, servers and systems, and is realized through the interaction between terminals and servers. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or it can provide cloud services, cloud database, cloud computing, cloud function, cloud storage, network server, cloud communication, intermediate Cloud servers for basic cloud computing services such as software services, domain name services, security service CDN, and big data and artificial intelligence platforms. The terminal may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a ...

Embodiment 2

[0074] This embodiment provides a system for identifying and interpolating abnormal traffic data.

[0075] A discrimination and interpolation system for abnormal traffic data, comprising:

[0076] The data acquisition module is configured to: acquire abnormal traffic data within a certain road section;

[0077] The abnormal data determination module is configured to: determine the type of the traffic abnormal data; the type of the traffic abnormal data includes missing data and erroneous data; wherein, the process of judging the erroneous data includes: judging the speed, flow and Whether the occupancy rate is within the set threshold range, if not, it is wrong data; judge whether the relationship between speed, flow rate and occupancy rate is logical, if not, it is wrong data;

[0078] The data filling module is configured to: fill the abnormal data to obtain the corrected traffic data in the road section.

[0079] It should be noted here that the above-mentioned data acqui...

Embodiment 3

[0081] This embodiment provides a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the steps in the method for identifying and interpolating traffic abnormality data as described in the first embodiment above are implemented.

Abstract

The invention belongs to the field of abnormal data processing, and provides a traffic abnormal data discrimination and interpolation method and system. The method comprises the following steps: acquiring traffic abnormal data in a certain road section; determining the type of the traffic abnormal data; the types of the traffic abnormal data comprise missing data and error data; wherein the error data judgment process comprises the following steps of: judging whether the speed, the flow and the occupancy of the road section are in a set threshold interval or not, and if not, determining that the road section is error data; judging whether the relationship among the speed, the flow and the occupancy meets logic or not, and if not, determining that the data is wrong data; and filling the abnormal data to obtain corrected traffic data in the road section.

Description

technical field [0001] The invention belongs to the field of abnormal data processing, and in particular relates to a method and system for distinguishing and interpolating traffic abnormal data. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the identification method of wrong traffic data is mostly the threshold interval identification method. The threshold interval is mainly based on the relevant information of the road section, and the threshold parameters are the effective value ranges of speed, flow rate and occupancy rate. By comparing the traffic data with the threshold interval, it is judged whether the data is abnormal. This method of discrimination is not comprehensive enough to distinguish the wrong data, and there may be cases of missed judgments. The filling method is mostly to calculate the weighted average of t...
