The coordination of signal controls in a traffic network has a significant impact on throughput
and journey times. Traditionally, signal coordination is optimized as a separate model step,
after route flows have been obtained from an assignment. A better integration of both steps
requires a model of signal coordination which admits a fast solution method. We describe
such a model and a solution based on mathematical optimization techniques for mixed-
integer problems. Compared to existing approaches, our method supports non-uniform cycle …
