文摘

Macroscopic fundamental diagrams can model the road traffic at an aggregated scale. This tool allows the evaluation of traffic management strategy at the city level while taking congestion into account. Something the usual macroscopic traffic models can’t do correctly at this scale. However, the calibration of the macroscopic fundamental relation is not easy since lots of factors, from experimental condition to traffic heterogeneities, can alter the shape of the diagram. We show that the use of electromagnetic loops can introduce huge variations in the macroscopic fundamental diagram (MFD) shape. Among the parameters that have considerable impact on the MFD shape, the traffic lights set up can alter it significantly. For a given network, a better knowledge of the link between the traffic light parameters and the MFD shape can help evaluate the network quality of service by computing the average traffic flow speed for the entire network.
