Abstract: To enhance resilience of urban road networks, a flexible signal control is proposed to mitigate period-dependent travel delay and random risk associated with hazardous materials (hazmat) transportation. A mathematical optimization model is presented to find period-dependent traffic responsive signal control subject to equilibrium traffic assignments. In the presence of hazmat transportation, a set of scenarios for uncertain exposure risk on links is investigated. A two-stage new solution scheme is proposed to solve a traffic responsive signal control in multiple periods. In order to demonstrate robustness of period-dependent signal control for hazmat transportation, numerical computations using realistic road network are made with recently proposed ones. These results reported obviously indicate that proposed period-dependent signal control can be more resilient than existing ones against a high-consequence of exposure risk in the presence of hazmat transportation.
