To prohibit facing passage of large-sized vehicles but to permit facing passage of small-sized vehicles by discriminating vehicles intending to pass.SOLUTION: Vehicle detection sensors 13, 14 or the like discriminate large-sized vehicles and small-sized vehicles at an approach route entrance of a construction tunnel 1, and also discriminate vehicles at a return route entrance. Then, entrance/exit of vehicles to/from an approach route and a return route is detected so as to share information of the vehicles traveling on the approach route and the return route. Traffic lights 16, 26 at the approach route and the return route are controlled based on the information. Then, entrance of vehicles into the construction tunnel 1 is prohibited/permitted so as to prohibit facing passage of large-sized vehicles but to permit facing passage of small-sized vehicles.SELECTED DRAWING: Figure 1
