Emergence of an Urban Traffic Macroscopic Fundamental Diagram

Research output: Working paperResearch

This paper examines mild conditions under which a macroscopic fundamen-tal diagram (MFD) emerges, relating space-averaged speed to occupancy in some area. These conditions are validated against empirical data. We allow local speed-occupancy relationships and, in particular, require no equilibrating process to be in operation. This means that merely observing the stable relationship between the space-averages of speed, flow and occupancy are not sufficient to infer a robust relationship and the emerging MFD cannot be guaranteed to be stable if traffic interventions are implemented.
