Household Flood Evacuation Route Choice Models at Sub-district Level
Flood evacuation route choice modeling studies gained its momentum in recent years. However, understanding how various explanatory variables determine flood route choice behavior of evacuees has not been fully investigated. The goal of this study is to understand flood evacuation route choice behavior of households at Bahay Toro and Sto. Domingo sub-districts in Quezon City, Philippines. Binary logit and probit models were estimated with variables selected through backward elimination stepwise method. Results include the presence of elderly person, departure timing, and mode used in evacuating as explanatory variables of households' route choice at Bahay Toro Sub-district. On the other hand, the number of family members, level of education and type of work of the household head, house ownership and the mode are variables that determine route choice of households at Sto. Domingo. Modeling evacuation route choice behavior representing the entire city can be further explored in future research.
