    Abstract

    This paper examines mild conditions under which a macroscopic fundamental
    diagram (MFD) emerges, relating space-averaged speed to occupancy in some
    area. These conditions are validated against empirical data. We allow local speedoccupancy 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.
