Transportation networks as a critical infrastructure are at increasing risk of flooding and thus disruption. The resulted disruption even in small flood events may impose indirect damages which needs to be quantified to better manage traffic flows. In this paper, a framework was developed to identify the vulnerability of transportation networks to flooding based on a state-of-the-art depth-disruption function which estimates flood depth impact on vehicle’s speed reduction. In this framework, the flood depth was modeled using a hydrodynamic model and then assigned to each road segment. Considering average daily traffic as the exposure component, flood depth as hazard, and speed reduction percentage as vulnerability, flood risk throughout the transportation network was quantified. The city of Houston in the state of Texas was chosen as a case study. Results show that this framework provides better insights into determining critical road segments and subsequently traffic management during rainfall events.
