Conditional Autonomous Surveillance in Public Transport

Public transportation vehicles have become occasional targets for terrorist attacks. Conventional closed circuit television surveillance has several limitations that make it of little use in managing these emergencies. This article describes a new smart surveillance system that has been designed to provide prompt, pertinent information for the management of emergency situations without infringing on the privacy of passengers during normal operations. The proposed system records and transmits information on the occurrence of an emergency event. The monitoring system watches its assigned space without retaining or transmitting any information under normal circumstances. However, when the device is triggered through sensors or manually, it can capture information in the form of a sequence of photo frames. Each triggered device sends an alarm to a central station and uploads its buffer of captured images to a central station. Once the buffer has been uploaded, it enters a real-time surveillance/communication mode that can supply pictures immediately to the control center. The system has been developed for three operational scenarios: surveillance, explosions and gunshots onboard underground metro/suburban rail trains; monitoring cabin occupancy under ferry/cruise vessel evacuation conditions; and monitoring doors and access to sensitive rooms on ferries or cruise vessels. A test of the prototype system on a metro network demonstrated the validity of the system.
