  • Method for anticipating tipping point of traffic resilience based on percolation analysis
    Patent number: 11430329
    Abstract: A method for anticipating the tipping point of traffic resilience based on percolation analysis, includes steps of: step (I) based on the topology structure of the urban road network and daily traffic operation data, constructing the urban traffic dynamical network; step (II): based on the urban traffic dynamical network constructed, analyzing the relationship between the system performance of urban traffic functional network and the congestion rate by percolation analysis; and step (III): based on the relationship between the system performance and the congestion rate, exploring the resilience function of the urban traffic functional network, and analyzing its resilience pattern and its resilience tipping point.
