Motivated by MP’s questionable performance in over-saturated traffic conditions and the importance of traffic homogeneity in the effectiveness of MFD-based PC, the concept of parallel application of the two strategies, acting in different network nodes but in a parallel scheme, is expected to increase overall system performance due to the controllers’ complementary nature. A method to identify critical nodes for MP control is developed, in order to allow partial MP application in fractions instead of all network nodes. Modified Store-and-forward dynamic traffic paradigm is used to test different control configurations for a real large-scale network. Results show the combined scheme more effective compared to separate controller applications while MP node selection method appears capable of increasing MP efficiency and applicability.Adaptive signal controlMax PressurePerimeter Control; critical nodesStore-and-ForwardMacroscopic Fundamental Diagram (MFD)Two-layer adaptive signal control framework for large-scale networks combining efficient Max-Pressure and Perimeter Controltext::conference output::conference paper not in proceedings
