A method for predicting the number of vacant parking spaces in a parking lot

Abstract

The embodiment of the invention discloses a new prediction method for the number of vacant parking spaces in a parking lot, including data preparation, the data is divided into a training set and a test set; normalization processing is performed on the data in the training set and the test set; The data is the analysis object, the fruit fly optimization algorithm is applied to the parameter optimization of the support vector regression model, and the optimal model parameters are selected to establish the support vector regression model with the best effect; the data in the test set is substituted into the support vector with the best effect In the regression model, the final remaining number of parking spaces is predicted. The implementation of the present invention can overcome the defects in the prior art such as too complicated calculation, slow operating efficiency, and insufficient prediction accuracy.

Description

technical field [0001] The present invention relates to the technical field of parking induction berth prediction, in particular to a new prediction method for the number of vacant parking spaces in a parking lot. Weighted Markov chain model, model combining wavelet transform and extreme learning machine (ELM), chaotic time series forecasting model, and model combining chaos and BP neural network, etc. From the perspective of innovation, the present invention creates a new prediction method in the parking guidance berth prediction technology. Compared with neural network algorithms, this method has the advantages of high stability and less parameters to be controlled. Background technique [0002] With the development of the domestic economy, people's living standards are constantly improving. There are more and more private cars, which directly lead to traffic congestion in the city. Parking problems have gradually become traffic problems, especially in the urban center of ...
