# Partial Outer Convexification for Traffic Light Optimization in Road Networks

@article{Gttlich2017PartialOC, title={Partial Outer Convexification for Traffic Light Optimization in Road Networks}, author={Simone G{\"o}ttlich and Andreas Potschka and Ute Ziegler}, journal={SIAM J. Sci. Comput.}, year={2017}, volume={39} }

We consider the problem of computing optimal traffic light programs for urban road intersections using traffic flow conservation laws on networks. Based on a partial outer convexification approach, which has been successfully applied in the area of mixed-integer optimal control for systems of ordinary or differential algebraic equations, we develop a computationally tractable two-stage solution heuristic. The two-stage approach consists of the solution of a (smoothed) nonlinear programming…
