Component

With the continuous growth of cities and the issues of insufficient space, indoor parking garages have become a vital component for any transportation system. Since emergencies will occur sooner or later, planning and organizing a successful evacuation plan with the aim of reducing the evacuation time as much as possible and controlling driver’s behavior is necessary. In this research, the authors present a systematic approach for the development and evaluation of evacuation strategies, through a state-of the-art sensitivity analysis process that provides faster convergence and thus lower computational burden. To demonstrate the proposed methodology, in this research, a simulation model is developed through AIMSUN for a three level indoor parking garage located in Athens, Greece. Four different scenarios with different evacuation strategies and plans are considered. A multi-step sensitivity analysis framework is implemented to overcome the uncertainties that could emerge from the model assumptions, model inaccuracy and data shortage. Moreover, sensitivity analysis is used to evaluate the consequences of the proposed scenarios and estimate the total time to evacuate the parking garage. The results of this research shows that the developed methodology provides significant reduction in evacuation time.
