Proposed Distributed System Architecture and Preliminary Measurements for the Detection of Trapped Individuals Inside Motorway Tunnels

This paper presents the architecture of a distributed system based on Bluetooth detectors for locating vehicles and people trapped in a motorway tunnel accident. The distributed architecture of the proposed system includes an automated dynamic way of adding or removing detectors from the system, a non-relational database for storing sensory measurements and an-easy-to-use graphical interface for displaying real-time or close to real-time detection information. The installation of the proposed system detectors is installed on the escape exits inside tunnels. The proposed system has been experimentally placed to both directions of a tunnel at the EGNATIA motorway in Greece and its functionality has been validated. Then, with the use of existing tunnel TMS inductive loop detectors, the accuracy of the detector measurements has been evaluated.
