To improve the accessibility of emergency vehicles after a large earthquake, it is important to quantify the effects of risk mitigation strategies. In this paper, using a simulation model that describes the movement of emergency vehicles amidst property collapse after a large earthquake, we evaluate street network accessibility in the Tokyo Metropolitan Area. Moreover, by analyzing the relationships between local environments and street network accessibility, we discuss the effects of risk mitigation strategies on improving street network accessibility.
