Method for calculating urban road flow velocity based on mobile phone signaling and OD attribute

Abstract

The invention discloses a method for calculating urban road flow velocity based on mobile phone signaling and OD attribute. The method comprises the following steps: a) obtaining traffic cell division information, road division information, cell base station information, road base station information and mobile phone signaling position information of a whole city; b) associating correspondence relation between mobile phone signaling data and traffic cell base stations in the whole city to obtain the correspondence relation between mobile phone signaling and the traffic cells, then, calculating an OD travel sequence of each mobile phone user by utilizing stay time of the each mobile phone user in each traffic cell; c) according to the road base station correspondence relation, filtering mobile phone signaling in the corresponding road range; d) carrying out secondary filtering on the mobile phone signaling through matching of time+ mobile phone number and the OD travel sequence; and e) calculating speed of a single mobile phone user on some road by utilizing the filtered signaling and by dividing position distance change by time, and then, by taking the average value of the data of all users on the road, calculating the road flow velocity.

Description

technical field [0001] The invention relates to the field of transportation management, in particular to a method for calculating urban road flow velocity which can filter out invalid samples by using mobile phone signaling. Background technique [0002] Under the premise that the traffic situation is becoming more and more complex today, and the data real-time and accuracy are higher, the signaling data of smart mobile terminals such as mobile phones has become the basic data of traffic analysis due to its large user base, wide range, and real-time generation characteristics. important source of . However, based on the positioning accuracy of mobile phone users based on 2 / 3 / 4G signaling, it is impossible to effectively distinguish mobile phone users driving on the road from other mobile phone users around the road (such as people walking, setting up stalls, working, etc.) on urban roads. The number of people is large and the speed of movement is low, so it is impossible to...
