Modeling Multi-Modal Traffic in Cities Using the 3D Macroscopic Fundamental Diagram

In this paper, the authors propose a new functional form for the three-dimensional Macroscopic Fundamental Diagram (3D-MFD). The 3D-MFD links the number of cars and buses in an urban network to the total travel production. The parameters of the proposed functional form are derived from the structure and topology of the road and bus network. The physical interactions of vehicles are described by a single parameter. Using simulation data from an abstract grid network the authors validate the proposed methodology and further demonstrate its applicability by applying it to empirical data sets from London and Zurich. Finally, the authors discuss policy relevant applications related to the passenger 3D-MFD.
