Three-in-one flyover

Abstract

The invention relates to a three-in-one flyover. The three-in-one flyover (picture 2) for simultaneous three-dimensional passing of pedestrians, two-wheeled vehicles and motor vehicles comprises straight high overpass bridges which are 6 meters higher than the ground, oblique straight inner ramps, oval high overpass bridges with turning bends, right turning bends, oblique straight outer ramps, motor vehicle lanes, two-wheeled vehicle straight lanes, long C-shaped bends, long C-shaped tunnels which are 3.5 meters lower than the ground, right turning bends, oblique straight ground ramps connected with tunnel entrances, a pedestrian tunnel which is 3.5 meters lower than the ground, pedestrian crossings, pedestrian step ladders, pedestrian entrance / exit bridges, two-wheeled vehicle lanes and pedestrian lanes; the highlight is generation of a three-in-one special effect for the simultaneous passing of the motor vehicles, the two-wheeled vehicles and the pedestrians; big and small lanes canbe combined for passing, no jamming is caused by crossing, jamming caused by turning of overlong vehicles is avoided, jamming caused by turning-induced externally throwing risk accidents on upward anddownward slopes is avoided, turning can be performed in advance, outgoing by two-wheeled vehicles is activated, exhaust pollution is reduced, less floor is occupied, and the cost is saved.

Description

technical field [0001] The invention relates to a three-in-one overpass suitable for simultaneous passage of motor vehicles, two-wheel vehicles and pedestrians at a crossroad. Background technique [0002] At the intersection of urban roads, traffic lights are used to exchange stop time for passing space. The speed limit is the first cause of traffic jams caused by slow vehicles. The capacity of road vehicles has been fixed, and slow vehicles are the unsolvable cause of stranded roads and blockages. Collisions and ramp accidents are also major causes of traffic jams. Traffic accidents involving two-wheeled vehicles crossing motor vehicles are quite serious. Long vehicles entering the city and making U-turns also lead to traffic jams. Multiple stops have cost people’s precious lives. Being emptied in the car, parking will cause increased brake loss and exhaust pollution. At present, the high-span interchange has a high risk of driving, and high-level construction risks. The c...

[0002] At the intersection of urban roads, traffic lights are used to exchange stop time for passing space. The speed limit is the first cause of traffic jams caused by slow vehicles. The capacity of road vehicles has been fixed, and slow vehicles are the unsolvable cause of stranded roads and blockages. Collisions and ramp accidents are also major causes of traffic jams. Traffic accidents involving two-wheeled vehicles crossing motor vehicles are quite serious. Long vehicles entering the city and making U-turns also lead to traffic jams. Multiple stops have cost people’s precious lives. Being emptied in the car, parking will cause increased brake loss and exhaust pollution. At present, the high-span interchange has a high risk of driving, and high-level construction risks. The cost of occupying off-road land is high, and the high cost of demolition is not conducive to traffic reconstruction, especially at present. The overpass bridge cannot solve the problem of simultaneous passage of motor vehicles, two-wheel vehicles and pedestrians, nor can it solve the problem of overpasses between large and small roads at intersections. At present, parking spaces are scarce, smog is worsening, and traffic accidents are prominent. Therefore, it is necessary to provide a Overpass with higher social benefits
