Title:

Highway Infrastructure Protection against Sea Level Rise: Game Theoretic Approaches for Cooperative and Competitive Decision-makers

Accession Number:

Record Type:

Component

Abstract:

This research investigates the influence of decision-maker behavior on policies that may be adopted for highway infrastructure protection against inundations resulting from sea level rise. The authors analyze two different types of games to represent this behavior and use the San Francisco Bay Area shoreline with a scenario of a 0.5m sea level rise as a case study. The objective of decision-makers is to minimize the traffic delay caused by inundations in the transportation network within their geographical boundaries. The model considers hydrodynamic interactions, traffic flow patterns changes as a result of inundations, and budget constraints on the protection costs. The hydrodynamics in the Bay Area are affected by the shoreline protection strategy: protection of a county’s shoreline may lead to increased inundations in another, unprotected, county. Furthermore, closure of a highway link in one county affects traffic delays in other counties due to traffic re-routing. Thus, protection decisions made by a county have potential impacts on other counties, and therefore other counties’ actions should be taken into account. Algorithms for both competitive (Nash) and cooperative games are developed. A Nash equilibrium is achieved among the counties when each acts to minimize its objective without the possibility of collaborating with other counties. The authors compare the results of Nash games with possible cooperation strategies for a range of funding scenarios. It is shown, through examples, that cooperation among counties increases benefits (reduction of Vehicle Hours Traveled) for all participants in most cases. In some cases, cooperation also reduces protection costs.
