英文摘要： Currently, we are faced with severe urban traffic congestions. The urban traffic planning and organizing level has been paid much attention. As an important fundamental data for ubran traffic planning and organization, traffic demand has been an important research topic for a long time. Since it is expensive to predict traffic demand by traditional surveys, as a new reseach direction, many new information sources are used. Based on large scale mobile phone data, we propose the theory of driver source prediction. The main contents of this project include: resident mobility model based on mobile phone data, prediction of traffic demand based on mobile phone data, prediction of driver sources on urban roads, analysis of the driver sources that cause traffic congestions. Using mobile phone data, we aim to accurately predict the residents' hourly locations and calculate trip distribution and O-D matrix. Through this method we try to find an economic and feasible way to predict traffic demand. By introducing the newest results of human mobility modeling to traffic demand prediction, we aim to understand the process of the formation of traffic flow by finding drivers' hourly locations. We will dynamically analyze the driver sources on roads, aiming to build a bridge between the fields of human mobility modeling and t
