The invention belongs to the technical field of traffic safety, and relates to a tunnel T-junction vehicle safe passing system and a control method, and the method comprises the steps: detecting the vehicle arrival condition of each junction through a sensing module; according to the vehicle arrival condition and the vehicle passing priority of each intersection, the light state of the light-emitting module is controlled through the control module, and the light state comprises green light on and red light off and green light off and red light on; after the vehicle passes, the control module controls the light state of the light-emitting module to recover to the initial state, and the initial state is that the green light is on and the red light is off. According to the invention, the sensing module detects the vehicle arrival condition at each intersection, and the control module controls the light state of the light-emitting module according to the vehicle arrival condition at each intersection and the vehicle passing priority, thereby solving the problem that traffic accidents are liable to be caused by vehicle passing conflicts at the T-shaped intersection of the tunnel.

The utility model discloses a kind of L-shaped overpass structures for T-shaped intersection, it is related to overpass technical field.The utility model includes a kind of overpass structure for T-shaped intersection, the plane of the overpass girder is oblique L-shaped, can be applicable to the T-shaped intersection of intersection angle 30~90 degrees, three directions of overpass are provided with ladder, ramp and straight ladder, the end of girder is provided with cantilever beam, and the straight ladder of three directions is arranged at cantilever beam place.The utility model solves the problem that three-way pedestrian crosses street in T-shaped intersection, the overpass can be applicable to the T-shaped intersection of different oblique angle, using conventional structure, easy to construction, beam height is smaller, complete function, high traffic efficiency, short detour distance, can satisfy the crossing demand of various pedestrians, such as general pedestrian, cart user, old person, disabled person etc..Meanwhile, solve the problem that the vertical fundamental frequency of footbridge does not satisfy and uses larger beam height, main beam and the leakage of joint of ladder, seismic beam safety protection is insufficient.
