Abstract
The analysis of travel behaviors of evacuees is an important premise of the exact estimation of network clearance time, and it is also an important issue in emergency evacuation. This paper aims at the household gathering behaviors of evacuees and establishes a location-choosing model for household gathering based on the linear programming modeling, with "Morakot" typhoon disaster as the emergency background. By introducing the priority factors of household members, the model gives humanistic considerations to the vulnerable household during the evacuation, and describes the travel characteristics of emergency evacuation by minimizing the total travel time of household members for gathering and the waiting time among gathering groups. Moreover, with the help of Matlab and Starlogo, the effects of household gathering behaviors on the total network clearance time in under-saturated, saturated and over-saturated scenarios are respectively simulated and compared. The results present that household gathering behaviors will lead to an increase of about 15% to the total network clearance time estimation.
