Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] see Figure 1-5 , a method for calculating road traffic based on 4G signaling data, comprising:
[0040] Step 1: Form a stay point library, first convert the original signaling into a stay point grid, and then perform deduplication, abnormal grid filtering and ping-pong switching filtering on the stay point grid to form a stay point library;
[0041] Step 2: Form the OD trajectory library, and use the time interval interruption method to interrupt the ...

The invention discloses a method and device for calculating road flow based on 4g signaling data, and the method comprises the following steps: 1, forming a stay point library, firstly converting original signaling into a stay point grid, and then carrying out duplication removal, abnormal grid filtering and ping-pong switching filtering of the stay point grid to form the stay point library; 2, forming an OD track library, and breaking the dwell point grid library of one day by using a time interval breaking method to form the OD track library; 3, separating people from vehicles, calculating the actual driving distance and average speed of the trajectory, and separating people from vehicles; and 4, road network matching by using the starting point and the ending point of the OD track, and using a road calculation engine to calculate a road. The method and device have the advantage of wide coverage range, and solves the problems that the existing urban road traffic monitoring mostly uses a plurality of bayonet cameras, the cost is high, the coverage rate is limited, the maintenance cost is relatively high, and most urban roads cannot be covered.
Description
technical field [0001] The invention relates to the technical field of urban road flow calculation, in particular to a method and device for calculating road flow based on 4G signaling data. Background technique [0002] Urban road traffic refers to the general term for the roads that are used for vehicle and pedestrian traffic in the city, provide people with work, life, cultural and entertainment activities, and are responsible for the accessibility of various areas in the city and the roads that are connected with the city's traffic outside the city. Ways (tools), mostly divided into motor vehicle lanes, non-motor vehicle lanes and sidewalks; at the same time, it is also a corridor for laying urban pipelines (ground pole lines and underground pipelines). In order to optimize the urban environment, urban roads are still within the separation zone and building control line Arrange green belts or sculpture artworks. Urban roads are generally divided into four categories: exp...
