An on-line control model for road tunnel with longitudinal ventilation was proposed based on neural networks and by combining traffic model,aerodynamics model and pollution model.Simulation was conducted with the model,where the traffic volume changed from 1 000 to 1 400(veh/h)and the benchmark emission rate was from 0.008 to 0.010 m~3/(veh·km).The results show that the proposed system increases or decreases the number of fans in realtime following the changes in the traffic volume and the...

An on-line control model for road tunnel with longitudinal ventilation was proposed based on neural networks and by combining traffic model,aerodynamics model and pollution model.Simulation was conducted with the model,where the traffic volume changed from 1 000 to 1 400(veh/h)and the benchmark emission rate was from 0.008 to 0.010 m~3/(veh·km).The results show that the proposed system increases or decreases the number of fans in realtime following the changes in the traffic volume and the benchmark emission rate,so that the volumetric fraction of CO,as a control target,is controlled just under the standard limit(150×10~(-6)).
