What is SMART?
How SMART Operates?
The SMART Tunnel was constructed primarily to mitigate the flooding problem in the city. However, as the incidences of major storms in a year are limited, as an additional function, it is able to provide traffic relief on the southern gateway to the city centre. This innovative and unique design poses a very challenging task especially during the operation of the tunnel. The operations of the SMART Tunnel is classified into 4 different modes, i.e.: -
Mode 1: No storm
No flood water will be diverted into the SMART system.
Mode 2: Moderate storm
The SMART system will be activated and flood water will be diverted into the bypass tunnel in the lower channel of the motorway. Up to this point, the motorway will still be opened to traffic.
Mode 3: Standby mode for major storm
The SMART system will be activated and the motorway will be cleared and closed to traffic. Sufficient time will be allocated to allow the last vehicle to exit the motorway. Tunnel is on standby mode for stormwater diversion into the motorway component.
Mode 4: Prolonged Major storm
The SMART system will be activated if heavy rain storm prolongs, and the motorway will be filled with stormwater after all the flood gates are opened. Motorway component will be used for passage of flood after traffic evacuation completed. The motorway will be re-
