Emergence of a urban traffic macroscopic fundamental diagram

Ranjan, Abhishek and Fosgerau, Mogens and Jenelius, Erik (2016): Emergence of a urban traffic macroscopic fundamental diagram.

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 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.
