<p>There are a few problems, recently, for jet fan ventilation of road tunnels as below. ①Change of the road construction height in the road tunnels ②Jet fan fall risk because they are over the car lanes ③Difficulty of approach check every year to the installed high position. To reduce these risks and difficulty and to improve, we plan jet fans to be smaller and set them to the outside over the car lanes and construction area for easy maintenance and easy handling. For that, CFD analysis was carried out and investigated for some same ventilating fans for 2 car lanes and one way longitudinal road tunnel ventilation.</p>
