Abstract
The application discloses a kind of interlayer equalization guiding dual-layer highway traffic flow regulation method and system.The application first constructs the vertical topology model of dual-layer road network including upper layer toll highway, lower layer free expressway and interlayer ramp, and quantifies the vertical impedance cost of vehicle when changing layer through ramp.Secondly, a multi-objective optimization model is established with the minimum total carbon emission of road network, the maximum operation benefit and the minimum user travel impedance as the target, and the interlayer equalization degree is introduced as the core evaluation index.Finally, NSGA-II and layer perception MSA nested algorithm are used to solve the Pareto optimal solution set, and the final rate scheme is determined according to the "equilibrium priority" principle.The application can realize the coordinated reorganization of traffic flow in vertical dimension, effectively alleviate the lower layer congestion, improve the overall efficiency of the system and reduce carbon emissions.
