Abstract

The invention belongs to the technical field of data processing, and provides a method and device for constructing a traffic flow data analysis model. The method comprises the following steps of establishing a data channel with a traffic flow data monitoring system, determining a corresponding road segment according to a target region, and extracting traffic flow data of the target region from thedata channel; acquiring historical traffic flow data of different sub-time periods of each road section at a set time period as a training sample; updating the training sample of each road segment according to the set maximum number of iterations, and obtaining an optimal fitness value of all road segments by utilizing a shuffled frog leaping algorithm; and obtaining a link weight by utilizing the optimal fitness value of all the road segments, and constructing the traffic flow data analysis model of a wavelet neural network according to the link weight. The method for constructing the traffic flow data analysis model provided by the invention fills the gap in the analysis tools for long-term traffic flow data, and improves the efficiency of traffic flow data prediction.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular, the present invention relates to a method and device for constructing a traffic flow data analysis model. Background technique [0002] With the development of urban traffic network, traffic flow is more likely to be affected by many factors, and the characteristics of randomness are becoming more and more prominent. At present, in response to this problem, the intelligent transportation system is used to collect the historical traffic flow data corresponding to the same period of time in the near future, and according to the collected content, the recent traffic flow is predicted. However, although this method can play a certain role in predicting real-time traffic flow data, none of them can be widely used as a long-term road condition analysis tool, and it is not helpful for long-term traffic flow forecasting. Contents of the invention [0003] In order to ove...
