Embodiment 1

[0041] As an optional implementation manner, the traffic state information is used to represent the continuously changing traffic flow of the corresponding traffic station within a historical time period.

[0042] In this embodiment, the traffic status information changes with time, and the corresponding traffic flow is also in a continuous and changing process. Therefore, the traffic status information can be used to indicate that the corresponding traffic station changes continuously in the historical time period traffic flow.

[0043] In related technologies, the existing models all adopt a fixed discrete form, but the embodiment of the present invention proposes a design framework based on continuously changing traffic flow modeling, and can output predictions of any time granularity through continuous modeling As a result, the usability and flexibility of the model in practical applications are greatly improved.

[0044] Optionally, the discrete traffic flow is converted...

Embodiment 2

[0128]Through the description of the above embodiments, those skilled in the art can clearly understand that the method for predicting traffic flow according to the above embodiments can be realized by means of software plus a necessary general-purpose hardware platform, and of course also by hardware, but many In this case, the former is a better implementation. Based on this understanding, the essence of the technical solution of the present invention or the part that contributes to the prior art can be embodied in the form of software products, and the computer software products are stored in a storage medium (such as ROM / RAM, disk, CD) contains several instructions to enable a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in various embodiments of the present invention.

Embodiment 3

[0160] In the embodiment of the present invention, by determining the status information of the traffic station, the corresponding delay is considered when updating the traffic station, so that not only the spatial information but also the time information are taken into account, and then it is closer to the real scene, and the improvement of traffic control is realized. The technical effect of the accuracy of traffic flow forecasting solves the technical problem of low accuracy of traffic flow forecasting.

[0161] Example 6

An embodiment of the present invention may provide a processor for predicting traffic flow, and the processor for predicting traffic flow may include a computer terminal, and the computer terminal may be any computer terminal device in a group of computer terminals. Optionally, in this embodiment, the foregoing computer terminal may also be replaced with a terminal device such as a mobile terminal.

[0162] Optionally, in this embodiment, the foregoing ...

Abstract

The invention discloses a traffic flow prediction method, a vehicle and a readable storage medium. The method comprises the steps that traffic state information of any two traffic stations in a traffic road is acquired, the distance between any two traffic stations is within a preset range, and the traffic state information is used for representing traffic flow of the traffic stations in a historical time period; the communication duration between any two traffic stations is obtained, and the communication duration is used for representing the duration needed when the traffic state information of the first traffic station in any two traffic stations is transmitted to the second traffic station; based on the traffic state information and the communication duration of the second traffic station, predicting a predicted traffic state of the first traffic station at a future moment; and determining the traffic flow of the first traffic station at the future moment based on the predicted traffic state. According to the invention, the technical problem of low traffic flow prediction accuracy is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for predicting traffic flow, a vehicle and a readable storage medium. Background technique [0002] At present, the intelligent transportation system is an important part of the city brain, and accurate traffic flow prediction is of great significance to the stable operation of the intelligent transportation system. [0003] In related technologies, a model with a stacked structure consisting of a time feature module and a space feature module is usually used, but this model cannot process time and space information synchronously, so there is a technical problem of low accuracy in traffic flow prediction. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] Embodiments of the present invention provide a method for predicting traffic flow, a vehicle and a readable storage medium, so as to at least solve the technical ...
