A method and a device for providing a public transport passenger flow distribution thermodynamic diagram

Abstract

The invention discloses a method for providing a public transport passenger flow distribution thermodynamic diagram, which comprises the following steps of: 1, receiving a passenger flow thermodynamicdiagram playing request of a set time period and a set line of a user; Step 2, acquiring a bus record on the set line within the set time period; Step 3, preprocessing the bus record to obtain an effective bus record; 4, the effective bus records are processed, the bus position of each time section and the passenger flow number of each time section are determined, and the time sections are a plurality of discrete time points formulated according to needs; And 5, drawing the thermodynamic diagram of each time section, and displaying the thermodynamic diagrams on the map in an overlapping manner. According to the method, the integrity of passenger flow data is ensured, interference data is effectively filtered, the accuracy of thermodynamic diagram display results is improved, meanwhile, the method is combined with geographic positions, the method is clearer, and the user experience is improved.

Description

technical field [0001] The invention relates to a method and a device for providing a thermal map of bus passenger flow distribution, and belongs to the technical field of computer Internet. Background technique [0002] For a long time, the distribution of bus passenger flow has been of great significance to the daily operation of bus companies. The existing method of generating a heat map of passenger flow distribution is to directly display the location information and the number of people in the car in the original data, but this method exists Larger interference data, some data still have certain positioning errors, the selection of passenger flow quantity and passenger flow location cannot accurately represent the actual passenger flow situation; at the same time, the existing passenger flow distribution heat Figure 1 Generally, pictures or pages are used for static presentation. Viewing the heat map of passenger flow at different time sections can only be switched man...

[0002] For a long time, the distribution of bus passenger flow has been of great significance to the daily operation of bus companies. The existing method of generating a heat map of passenger flow distribution is to directly display the location information and the number of people in the car in the original data, but this method exists Larger interference data, some data still have certain positioning errors, the selection of passenger flow quantity and passenger flow location cannot accurately represent the actual passenger flow situation; at the same time, the existing passenger flow distribution heat Figure 1 Generally, pictures or pages are used for static presentation. Viewing the heat map of passenger flow at different time sections can only be switched manually, and then the heat map of each time section is compared separately. change of location
