Technology Evolutionary Games in Complex Transportation Systems in the Face of Adaptive Adversaries

There exists an evolutionary game between transportation systems and adaptive adversaries. The strategic interactions have high impacts on complex transportation systems, not only to security infrastructure, technologies, and costs, but also to the general public’s travel pattern and welfare. In this research, we utilize evolutionary game theory to model the interactions between adaptive adversaries (such as terrorists) and transportation systems (including transportation authorities, companies, and the general public). All players adapt their strategies to the other players’ previous choices. By this, players maximize their own payoffs or welfare according to their preferences, and are subject to their own budget constraints. This research provides a general theoretical framework for decision-making in complex transportation systems in the face of adaptive adversaries, and provides managerial insights on when and where to adopt what technology in order to maximize the (long-run) social welfare of transportation systems.
