Travel Behaviour Analysis of Local Residents during Evacuation in the Event of Tsunami in Bali Province

Abstract

This study investigates local residents travel behaviour in Bali Province during evacuation in the event of a tsunami. The analyses include shelter and human response time choices. Data were collected by distributing Stated Preferences (SP) questionnaires to local residents from two coastal areas of Kuta and Sanur. Data include household preferences to shelter and response time choices, personal data, socio-economy, a distance of residence to the coastline, and the experience of natural disasters. The analyses are conducted using binary logistic regression model. The study shows that significant factors influencing shelter choices are education levels, car ownership and no natural disaster knowledge. Significant factors influencing response time choices are age, a household with total income per month less than 3 million rupiahs, and car and motorcycle ownerships. The study suggests that the local government should begin to disseminate the alternative types and locations of shelter during an evacuation, considering the limited ability of the government in providing shelter in case of a tsunami. In addition, the local government is expected to consider the types and number of mass transport fleet that must be provided when the tsunami hit.
