Deriving the Macroscopic Fundamental Diagram for an urban area using counted flows and taxi GPS

This paper applies the Macroscopic Fundamental Diagram (MFD) and the Generalized Macroscopic Fundamental (GMFD) Diagram to estimate traffic characters for an urban area. The authors used traffic flow data manually counted from intersection traffic video and taxi Global Positioning System (GPS) data to derive MFD and GMFD. The method is suitable to recognize traffic situation. These figures show the property of the road network, which consists of infrastructure and control. Mastering the properties of the network supply side, the authors can better manage and control traffic demand. In the process of data analysis, the authors found that the time step for data processing is a determinant for the MFD and GMFD shapes. That means different time step produces different results.
