A descent framework for linked signal system with network flows

摘要

Optimization of linked signal system in urban traffic road networks is considered in this paper. This problem can be formulated as a nonlinear program subject to network flows following Wardrop’s first principle in which traffic rerouting effects are taken into account. We propose a descent framework to effectively solve a linked signal system with network flows. Numerical calculations are implemented on well-known example road networks and good results are reported.
