Surrogate-assisted cooperative signal optimization for large-scale traffic networks

no code implementations3 Mar 2021 Yongsheng Liang, Zhigang Ren, Lin Wang, Hanqing Liu, Wenhao Du

The decomposition operation significantly narrows the search space of the whole traffic network, and the surrogate-assisted optimizer greatly lowers the computational burden by reducing the number of expensive traffic simulations.
