# Planning Urban Internal Transport Based on Cell Phone Data
## 1 Introduction  
In the era of the popularization of mobile phones, scholars can extract a large number of data samples from cell phones during the process of using them for related planning research. Compared with traditional survey methods, mobile phone surveys have many advantages, such as low cost, wide coverage, and less processing time, and they have been conducted for multiple aspects of research in different fields by many scholars.  
In the application research of urban transportation planning, the travel origin-destination (OD) survey is an important reference basis for solving traffic problems. It objectively and truly reflects the traffic flows between districts and the overall situation of residents' travel. As an indispensable communication tool in people's daily lives, mobile phones record for a long time, and at the same time, the penetration rate of mobile phones in life is high. The activities of urban residents can be monitored through mobile phones, and mobile phone data have great potential in the analysis of population travel behavior. Therefore, this paper processes the signaling data of mobile phones to extract the travel characteristics of users, thereby revealing the spatial structure of travel demand.  
ArcGIS is a desktop application GIS platform that integrates spatial data display, editing, query retrieval, statistics, report generation, spatial analysis, and advanced mapping. It can comprehensively process geospatial-related information and solve complex analysis problems, and has strong information processing capabilities, which are widely used in transportation network analysis and spatial layout research of transportation facilities, which reflects the high credibility of ArcGIS spatial analysis technology analysis simulation. Therefore, this article used ArcGIS software based on cell phone data and policy documents related to urban transportation planning and urban transportation road networks. We obtain important transportation facilities data and other information from transportation planning documents, and we process cell phone data through ArcGIS to obtain the travel OD spatial distribution. We sort out the flow of people across districts in Wuxue city,count the amounts of exchanges, and get the intensity of traffic connections between districts. Then, we use this network data to construct a traffic network model of Wuxue City, analyze the problems of Wuxue City traffic planning, modify the planning deficiencies, verify the optimization of the modified plan by comparing the calculation models, such as accessibility and density analysis, and verify the rationality of the planning analysis method. Finally, we summarize the application and advantages of mobile phone data for intra-city traffic planning, and the direction of future research. The results of the OD study on residential mobility can provide help and references for local governments in urban transportation planning and resident travel planning. At the same time, we hope that our planning proposals can provide references and guidance for transportation planning in Wuxue City and other similar small- and medium-sized cities.
