eVAC: Emergency Evacuation System

Team communication system to support city-wide evacuation coordination for significant events in a city.

Our application was inspired by the issues raised by the Selwyn District Council from the recent Canterbury flood of July 2017. The eVAC application provides an ecosystem to support communication between Search & Rescue Managers, Field Crews, Emergency Services and Citizens. During an emergency communication and coordination for the search and rescue team is critical.

eVAC provides a website and mobile application that supports a search and rescue (SAR) evacuation coordination system that allows:

  • SAR Manager to View city maps, View areas to evacuate, View field crews in maps, View properties with their status, Assign an area to a team, Initiate a chat with field crew, alert emergency services for critical situations, see overall response status
  • Citizen Homeowner to Register their home, Receive warning or evacuation alerts, Report status of their home and family
  • SAR Field Crew to Receive their area assignment, View a list of properties to asses and clear, Report on property status

eVAC is in place for safer citizens.

The system is also generic so can be used for floods, fires, earthquakes or tsunamis.  This system could be widely used for a variety of city situations.
