Safety in automated transportation tunnels

This paper explores the main safety features in Dubai International Airport (DIA) tunnel. The safety levels have been enhanced because of using centrally controlled electromechanical systems and ITS (Intelligent Transportation System) components and all operated by SCADA (Supervisory Control And Data Acquisition) technology. Redundancy of critical devices is ensured to maintain continuous back alternatives in case of systems defects or partial failures. The overall safety aspects whether related to motorists or workers in the tunnel are accordingly improved due to use this sophisticated industrial hierarchy system and carefully designed structure.
