Tunnel Ventilation Control System Using Real-time Traffic and Ventilation Simulator

This paper describes a new tunnel ventilation control system called Model-based Predictive Ventilation Control (MPVC). The new system uses real-time traffic and ventilation simulators and it is possible to reduce at least 20 % or more of electricity consumption compared to previous tunnel ventilation control systems. This new control software has been already installed in 7 tunnels including the 1st and 2nd longest tunnels in Japan.
