Digital emergency response technologies research of transportation infrastructure network: a review and prospects

Nowadays, the rise of various unexpected incidents on a global scale makes the management and control of emergency transportation popular research in the field of the transportation infrastructure network. The development of digital technologies has injected new impetus into emergency traffic management in recent years. Such advancement poses a significant impact on the efficiency of evacuation, resource dispatching, and supplies technical support for the construction of emergency transportation system. In this study, we review recent literature on digital emergency disposal technologies of the transportation infrastructure network, including geographic information system (GIS), Internet of things (IoT), cooperative vehicle infrastructure system (CVIS), big data technology, and intelligent transportation system (ITS), etc. It is found that digital technologies have unique advantages and application potential in the prevention, early warning, and rescue of unexpected accidents than traditional emergency transportation management. Finally, we summarize the characteristics of the current effort and propose future research directions.
