The fire detection in tunnel was researched by simulation and pool fire experiment.Pool fire experiments of fire under the car or fire behind the car were done and the fire in engine cabin or passenger cabin was simulated.Only closed circuit television image detector and smoke detector can detect the fire under the car.Response time of detector by fire in passenger cabin is longer than that in engine cabin.All kinds of detector have no response to fire in a car which moving at 50 km/h.2 and more kinds of detector used at same time was suggested.
