Abstract

The invention discloses a short-time prediction method for future parking space demand quantity in a closed area, which is used for predicting the parking space demand quantity of a certain closed area in future hours, so that managers can effectively manage and schedule facilities of parking lots on roads in the area. The invention provides a deep learning theory-based recurrent neural network parking space demand prediction model of an LSTM (Long Short-Term Memory) unit, and the parking space demand corresponding to a subsequent time point is predicted according to the parking space demand variations of previous hours. Certain Hangzhou University is taken as an experimental object, and data of two random days and two specific days are adopted for practical verification. Results show thatthe LSTM recurrent neural network module is adopted to predict the parking demand in the area, the result is closer to the actual value than that of a traditional method, the precision is satisfactory, and it is indicated that the prediction method is feasible and effective.

Description

technical field [0001] The present invention proposes a cyclic neural network berth demand forecasting model based on LSTM units based on deep learning theory, and predicts the berth demand corresponding to subsequent time points according to the change in berth demand in the first few hours. It is a method for predicting the number of berths in a short period of time in the future in a closed area. Background technique [0002] The prediction of berths in a region is an important prerequisite for traffic regulation and control in a region, and it is one of the key technologies to realize intelligent parking. [0003] Prediction and early warning of changes in the number of berths in a closed area can help to predict in advance that there will be too many cars or even road congestion in the area, and make corresponding countermeasures to alleviate it, which is helpful for alleviating traffic congestion in the area and effectively using parking spaces Resources play an impor...
