Embodiment

[0036] Such as figure 1 As shown, the present invention provides a method for identification of residents' rail transit travel modes based on mobile phone signaling data, the steps of which are as follows:

[0037]Step 1. Obtain all mobile phone signaling data sets during residents’ daily trips, extract the base station data in the data set, and use a circle with a radius R to cluster the base stations into base station aggregation points. In this data set, if a resident stays at the same base station gathering point continuously for t minutes or more, the base station gathering point is taken as the effective travel segment segmentation point of the resident, which is defined as the joint residence point. Using the joint residence point, the daily travel of the resident is divided into multiple effective travel segments G(1), G(2)...G(i)...G(N), where 1<=i<=N, N is The total number of divided valid travel segments, counting all mobile phone signaling data in each valid trave...

Abstract

The invention provides a cellular signaling data based track traffic travel mode identification method for a resident. The method is characterized by comprising the steps of obtaining all cellular signaling data in daily travel of one resident, identifying an effective travel section, constructing a geographic grid system, mapping a track traffic route and the effective travel section into the geographic grid system, and recording position information by using a grid coordinate sequence; and in the grid system, judging whether the travel belongs to the track traffic travel or not according to the position matching of the effective travel section and the track traffic route, the track similarity and an average speed value of the travel section. According to the method, high-timeliness and high-precision judgment on a track traffic travel mode is realized by utilizing mass cellular signaling data; and the method is favorable for a traffic management department to accurately master track traffic route information and reasonably plan the track traffic route, and has an important significance for improving the living quality of residents and the satisfactory degree of city traffic.

Description

technical field [0001] The invention relates to traffic planning and computer application technology, in particular to a method for identifying travel modes of rail transit for residents based on mobile phone signaling data. Background technique [0002] In terms of modern urban transportation planning, reasonable planning of rail transit lines and rail transit stations can effectively solve the problem of road congestion in certain areas of the city and improve the travel efficiency and quality of residents. In order to reasonably plan rail transit lines, it is first necessary to obtain information on rail transit modes in residents’ travel, which can be used for technical support for line planning after analysis. [0003] The traditional ways to obtain travel information of residents are divided into manual survey, video surveillance portrait recognition and IC card data statistics. Manual investigation will greatly reduce the timeliness and applicability of the current r...
