In the recent past, Macroscopic Fundamental Diagram (MFD) proved to be an attractive alternative to describe the traffic states at the network level. Several works (Knoop and Hoogendoorn, 2014, Yildirimoglu and Geroliminis, 2014, Kouvelas et al., 2017) employed MFD-based approaches in variety of applications like perimeter control, modeling large-scale cities, etc. Even though Geroliminis and Daganzo (2008) verified the existence of MFD, the stability of its shape faces certain challenges like hysteresis phenomenon (Gayah and Daganzo, 2011), heterogeneity of the traffic in urban networks (Geroliminis and Sun, 2011). Ji and Geroliminis (2012) has shown that partitioning of heterogeneous networks into homogeneous regions can be a solution to obtain a well defined MFD. However, this approach might not be robust as hysteresis may be driven by other factors rather than the network attributes.
