Small-sized full intercommunication overpass road junction

The invention discloses a small-scale full interchange crossing, which comprises a cross-shaped or trifurcate or special crossing, wherein a round barrier formed by the combination of a flower bed, flowers and grasses and fingerposts is arranged in the crossing; motor vehicle loops are arranged outside the round barrier and are communicated with motor vehicle lanes; loop underpass tunnels with a plurality of daylight openings outside the motor vehicle loops are communicated with non-motor vehicle lanes of the crossing through underpass approaches; and loop overpasses, approaches and pedestrian loops are arranged outside the tunnels and are communicated with sidewalks of the crossing. The small-scale full interchange crossing has the advantages that: the small-scale full interchange crossing ensures that people and vehicles can make three-dimensional pass at the crossing, improves the pass flow of the crossing and the turning velocity, avoid the cut-in of transverse and longitudinal vehicles and pedestrians at the crossing from causing traffic accidents, has time-saving pass and short back haul and energy conservation of vehicles, ensures that the pedestrians pass through the crossing from the pedestrian loops during the low valley of the pass that no traffic stream exists at the crossing and pass through the crossing from the loop overpasses during the rush hours of the pass that the crossing is occupied by the transverse and longitudinal vehicles, is most suitable for being implemented at small crossings, removes red and green lights which occupy energy for ever, and does not need to always occupy traffic polices and traffic wardens at the crossing.
