Traffic Information Description And Reasoning Research On Mobile Phone Location

With the acceleration of urban development process,the problem of traffic congestion is becoming more and more serious.It has seriously affected the residents' travel,and it is urgent to solve the problem of traffic congestion.The key technology to solve the traffic congestion problem is traffic information collection.Big data and "Internet plus" has become the forefront of the development of the times,mobile phone has become an important means of information exchange.Based on the Android mobile phone software platform of APP system,according to the user's travel information,through the Baidu SDK positioning package to complete the mobile phone location data read and data cleaning and processing to obtain valid data,and for effective data visualization.The main research work of this paper is as follows:In this paper,firstly,the principle and implementation of mobile phone positioning technology are studied.Based on the analysis of common mobile phone positioning technology,aiming at the traffic congestion problem,the location of traffic mobile data using A-GPS is proposed.Secondly,through the study of spatio-temporal data,we design the spatiotemporal data acquisition system,and develop the data acquisition and app system based on Android system platform.Finally,the collected data is cleaned and pre processed,and the two-dimensional data expression is carried out in the visual platform interface ArcGIS.In order to verify the reliability and accuracy of the system,a number of key congested roads in the central city of Jilin,Changchun province were selected to test the system.The test results show that the positioning technology and data processing technology used in this paper are effective for dealing with traffic congestion problems,and have practical engineering significance for solving traffic congestion problems.
