Parking demand pre-estimation method and parking demand pre-estimation device

Abstract

The invention relates to the electronic communication technology field and particularly relates to a parking demand pre-estimation method. According to the method, fluctuation curves are generated, a dynamic change function of parking demands relative to the vehicle flow data of vehicle flow mounting sites is established according to a time delay coefficient of each vehicle flow mounting site, a comprehensive pre-estimation function is established according to a weight coefficient of each vehicle flow monitoring point and the corresponding dynamic change function to acquire relatively precise pre-estimation parking demands. Quantitative analysis is acquired through establishing relationships between the parking demand fluctuation curve and the vehicle flow fluctuation curve; parking demands are comprehensively acquired through influence weight of multiple vehicle flow monitoring sites on parking demands; more preceise pre-estimation about parking demands is acquired through calculating different time delay effects. The method is advantaged in that a function module framework can be successfully combined through establishing function modules, and a computer program stored in a readable computer storage medium can be utilized for enforcement.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a parking demand estimation method. As for the parking demand estimation method, functional modules can be established, combined into a functional module framework, and implemented by a computer program stored in a computer-readable storage medium. Background technique [0002] With the development of the city, the number of cars in the city is increasing, and the parking demand has become a difficult problem in urban management. In order to better manage parking, it is necessary to estimate parking demand in various areas of the city. At present, in order to estimate the parking demand, the industry has introduced a heat map to analyze the demand for car pickup. The heat map can reflect the traffic flow in the area and can reflect a certain parking demand. However, due to the various factors affecting the parking demand, the car Traffic flow and parking demand...

At present, in order to estimate the parking demand, the industry has introduced a heat map to analyze the demand for car pickup. The heat map can reflect the traffic flow in the area and can reflect a certain parking demand. However, due to the various factors affecting the parking demand, the car Traffic flow and parking demand cannot directly establish a linear correlation, but the current analysis method rarely obtains quantitative analysis data, and more judgments are based on subjective feelings of heat maps

[0003] On the other hand, the current analysis is mainly based on one day as an analysis unit, and the comparison between the heat map and the previous heat map is used to predict the parking demand of the day. time period with relatively frequent operation) to make timely prediction and response to parking demand, however, the current prediction methods are still difficult to achieve this point
