A three-dimensional macroscopic fundamental diagram for mixed bi-modal urban networks
Recent research has studied the existence and the properties of a macroscopic fundamental diagram (MFD) for large urban networks. The MFD should not be universally expected as high scatter or hysteresis might appear for some type of networks, like heterogeneous networks or freeways. In this paper, we investigate if aggregated relationships can describe the performance of urban bi-modal networks...
متن کاملPerimeter flow control of mixed bi-modal urban road networks
In this work we deal with the perimeter flow control problem of bi-modal urban networks by use of a three-dimensional Macroscopic Fundamental Diagram (3D-MFD). The 3D-MFD relates the accumulation of cars and buses and the outflow (or circulating flow) in a bi-modal traffic network. We assume that the impact of each mode on the traffic flow in the network is different, i.e. each bus can not be c...

متن کاملMacroscopic modelling and robust control of bi-modal multi-region urban road networks
The paper concerns the integration of a bi-modal Macroscopic Fundamental Diagram (MFD) modelling for mixed traffic in a robust control framework for congested singleand multi-region urban networks. The bi-modal MFD relates the accumulation of cars and buses and the outflow (or circulating flow) in homogeneous (both in the spatial distribution of congestion and the spatial mode mixture) bi-modal...
متن کاملAn analytical approximation for the macroscopic fundamental diagram of urban traffic
This paper shows that a macroscopic fundamental diagram (MFD) relating flow and average density must exist on any street with blocks of diverse widths and lengths, but no turns, even if all or some of the intersections are controlled by arbitrarily timed traffic signals. The timing patterns are assumed to be fixed in time. Exact expressions in terms of a shortest path recipe are given, both, fo...
