Evacuation shelter and route selection are indispensable parts of emergency planning. An efficient plan can effectively evacuate people from a dangerous place to a safer location. Meanwhile, it is crucial to improve risk management. This article ...

This paper focuses on indoor evacuation path planning problem where the objective is to find evacuation paths for each evacuee such that the evacuation egress time is minimized. Since paths are dependent on the distribution of evacuees, initial ...

The management of large-scale traffic evacuation involves various complex post events and response activities in addition to the real-time identification and possible mitigation of the crisis. To capture the numerous and varied decision-making ...

With the rapid growth of mobile devices and applications, geo-tagged data is becoming increasingly important in emergency management and has become a major workload for big data storage systems. Traditional methods that storing geospatial data in ...

Hurricane Sandy made landfall in one of the most populated areas of the United States, and affected almost 8 million people. The event provides a unique opportunity to study power outages because of the data available and the large impact to a densely ...

Social media play an important role in emergency response. With Twitter data were widely used in emergency management, this paper attempted to extract valuable information from microblog data to support emergency response. Event-related microblog data ...

Detecting dangerous situations is crucial for emergency management. Surveillance systems detect dangerous situations by analyzing crowd dynamics. This paper presents a holistic video-based approach for privacy-preserving crowd density estimation. Our ...

With the advances of information communication technologies, it is critical to improve the efficiency and accuracy of emergency management systems through modern data processing techniques. The past decade has witnessed the tremendous technical advances ...

The 2014 West African Ebola Outbreak rised from Sierra Leone, Guinea, and Liberia at December in 2013 has been reported to cause 21296 cases and 8429 deaths until now. Besides that, Typhoon Haiyan and Typhoon Hagupit are also the serious disaster ...

Nowadays, the public transportation safety situation continues to deteriorate, and malignant incidents occur sometimes. Therefore, there is great need for the improvement of safety levels by the authorities. To this end, we propose PTEMS, a novel public ...

Public transport is an indispensable element of a modern society and is of sustained interest to emergency management authorities worldwide. In this paper, the design of an emergency management system for public road transport networks is presented. The ...

Information plays an important role in disaster response. In the past, there has been a lack of up-to-date information following major disasters due to the limited means of communication. This situation has changed substantially in recent years. With ...
