Transportation networks are critical civil infrastructures susceptible to natural and man-made hazards. Ensuring the networks sustain the disaster impact and retain their traffic carrying capacities is essential in mitigating system functional loss and in facilitating emergency evacuation. Due to the constraint of limited resource, it is vital to manage disaster mitigation resources with a strategic budget planning. This paper proposes a new methodology to develop an optimal budget planning strategy with a traffic-independent network flow measure. The uncertainties of earthquake intensity are considered by using the Monte Carlo simulation framework with the state-of-the-art bridge fragility curves and damage-functionality relationship. The methodology is demonstrated with the transportation network in Memphis, TN, by proposing bridge retrofit program and strategic budget planning. The findings provide useful information for government agencies and emergency managers to make better decisions on strategic budget planning.
