As the population of urban centers grows, there is a significant challenge of adjusting the transportation needs of urban mobility, as well as pursuing environmental protection strategies and ensuring social inclusion. The major bottleneck of urban mobility includes the constant traffic congestion in major cities because of excessive use of private...

Transportation planning is vital in the current scenario of rapidly growing populations, travel changes, and demand. With the emergence of the COVID-19 pandemic, socio-economic conditions in society are exerting significant strain on transportation infrastructure. These conditions might affect not only the transport demand and infrastructure but al...

This study aims to identify the factors affecting household evacuation travel behavior when the Taal volcano erupted in January 2020. The data utilized were collected from selected households in Sampaloc, Talisay, Batangas. Correlation analysis and logistic regression were used to analyze the data. Evacuation behavior separately analyzed here inclu...

Emergency evacuation is the immediate escape of people away from a place of an imminent threat to a place of safety. The ability of the households to evacuate is a crucial component in reducing disaster risks. Logistical issues such as a lack of resources during and after the evacuation, as well as road congestion, might arise, especially in short...

Understanding evacuee behavior is important to minimize the loss of lives and manage evacuation in the future. Evacuation destination choice entails the decision of affected people regarding where to stay, away from an impending hazard. This study investigates the factors considered by households when choosing where to go during an evacuation perio...

Analysis of influential factors to evacuation decision, a key input to evacuation planning, is important for better management in future evacuations. Evacuation decision indicates the choice of households to fully, partially evacuate or stay from the area at risk of impending hazard. This study aims to develop a model of flood evacuation decision u...

In today's fast-paced world, the need of practical activity-based travel demand models for special generators like universities need further development. Better understanding of how people organize and schedule their activities gives more solid basis for travel demand modelling which is being addressed in the activity-based approach to travel deman...

The need for better evacuation management is becoming inevitably important as a preparedness measure to minimize negative impacts of disasters. One of the essential aspects necessary for evacuation modeling and management is taking into account the travel behavior of evacuees. This study was conducted to understand the evacuation route choice behav...

Increasing frequency and severity of hazards that lead to devastating disaster impacts demand building substantial response capability. Evacuation is seen as one of the effective measures to avert disaster impacts. Planning and modeling of effective evacuation incorporate evacuation travel behavior. This study seeks to identify and understand the e...

Evacuation is one of the important preparedness measures in disaster management. It requires careful modeling and planning to minimize chaos and confusion during evacuation operations. The choice of decision-makers, whether to evacuate or stay in the area threatened by hazard, is an important aspect of evacuation travel behavior research. This is c...

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 su...

Modeling evacuation departure time is primarily essential in evacuation demand modeling. In this study, a discrete choice model is used to understand the decision of evacuation departure time of households in flood affected areas in Quezon City, Philippines. Specification of the model is also validated. Results of the study provide useful insights...

Flooding is viewed by many as a natural phenomenon, which is necessary for biodiversity. However, with the anthropogenic activities brought about by changes in land-use and climate, floods are observed to be more frequent and severe. In order to avert the negative impacts of flood, preparedness measure such as evacuation is increasingly necessary....

Evacuation decision during flood disasters indicates the choice of households to evacuate or stay from area at risk. This may be viewed as simple decision but involves complex behavioral and other external factors. Evacuation decision serves as key input to transportation planning in the event of flood, hence, careful consideration of the factors t...
