Transportation System Vulnerability Assessment considering Environmental Impact

نویسندگان

چکیده

Transportation system has a close bearing on the prosperity of society. However, transportation infrastructures are highly vulnerable to extreme events. Therefore, identifying most critical component is among first priorities network planners and managers. This paper proposes novel framework identify for road system. A key characteristic vulnerability assessment travelers’ response changes in topology capacity after an event. Hence, problem formulated as nonlinear programme with equilibrium constraints, considering route choice behavior. In methodology, two types measures developed assess system, namely, travel time-based (STTV) emissions-based (SEV). The former basis short-term planning, while latter put forward long-term planning. With these measures, proposed then demonstrated using extended Nguyen-Dupuis under different demand levels degradation levels, taking into account modes: bus car. results indicate that can similar components. Moreover, it shown SEV find more components than STTV regardless or growth. Our research helps create recovery plan by assigning priority infrastructures.
