Problems solved by technology

If WIFI positioning data can be obtained, it is easier to analyze road traffic. However, it is difficult to obtain WIFI positioning data and the coverage area is narrow. In most cases, only base station positioning data can be obtained, which causes a greater impact on road traffic analysis Difficulties, especially when recording vehicle turns at intersections
[0004] Because the coverage of the base stations may overlap or fail to cover the whole road, choosing one or two base stations as the base station for judging the direction will easily lead to inaccurate steering judgment

Embodiment 1

[0043] An intersection turning traffic analysis system based on base station signaling data, including a data acquisition module, a storage module and a processing module;

[0044] The data acquisition module is used to obtain the latitude and longitude information of the intersection, the latitude and longitude information of all base stations in the area to which the intersection belongs, and the latitude and longitude information of each turning direction of the intersection, and upload the latitude and longitude information;

[0045] In this embodiment, a certain crossroad is taken as an example, and the four turning directions of the crossroad are respectively marked as A, B, C, and D;

[0046] The storage module is used to store latitude and longitude information;

[0047] The processing module is used to calculate the distance between each base station and the intersection through the latitude and longitude information of the intersection and the latitude and longitude ...

Embodiment 2

[0059] The difference between the intersection turning flow analysis system based on base station signaling data and the first embodiment is that the processing module calculates the switching time of each signaling data between identification groups after the signaling data is grouped according to the user identification number, and the switching time is passed through the switching time. Calculate the user's moving speed, and then use the Kmeans clustering algorithm to identify the user's travel mode, and select the signaling data of the car travel as the signaling data for judging the steering.

Embodiment 3

[0061] Such as figure 1 As shown, in order to realize the intersection turning flow analysis system based on base station signaling data, the present invention also provides the intersection turning flow analysis method based on base station signaling data, comprising the following steps:

[0062] S1. Obtain the latitude and longitude information of the intersection and the latitude and longitude information of all base stations in the area to which the intersection belongs;

[0063] S2. Calculate the distance between each base station and the intersection through the latitude and longitude information of the intersection and the latitude and longitude information of the base station;

[0064] S301. Select all base stations whose distance from the intersection is greater than the threshold α and less than the threshold β as judgment base stations, wherein the range of the threshold α is 100-300 meters, and the range of the threshold β is 900-1200 meters; in this embodiment, th...

Abstract

The invention discloses a crossing turning flow analysis system and method based on base-station signaling data, and relates to the field of road flow analysis. The system comprises a data collectionmodule, a storage module and a processing module. The data collection module is used to obtain latitude and longitude information of a crossing and latitude and longitude information of all base stations of an area to which the crossing belongs, and uploads the latitude and longitude information; the storage module is used to store the latitude and longitude information; and the processing modulecalculates distances between the base stations and the crossing according to the latitude and longitude information of the information and the latitude and longitude information of the base stations,selects all base stations whose distances to the crossing is greater than a threshold alpha and lower than a threshold beta as determining base stations, and divides the determining base stations intoidentification clusters in different directions. The threshold alpha ranges from 100 to 300m, and the threshold beta ranges from 900 to 1200m. Thus, proper base stations can be select to form base station clusters so as to determine vehicle turning.

Description

technical field [0001] The invention relates to the field of road flow analysis, in particular to an intersection turning flow analysis system and method based on base station signaling data. Background technique [0002] With the rapid development of society and economy in today's society, the flow of roads is increasing, and the load capacity of many roads is stretched. Therefore, accurate analysis of road flow conditions can provide useful information for road construction planning, solving road congestion, and traffic police attendance. [0003] Road flow analysis includes two components: one is the flow analysis of each road section. The second is the analysis of the turning situation of the traffic at each intersection. Both types of analysis need to be based on positioning data, and positioning data includes GPRS positioning data, WIFI positioning data and base station positioning data. The base station positioning data depends on the dotted data on the base statio...
