Rapid unblocked urban road intersection interchange system
InactiveCN102561129AImprove traffic capacitySuitable for retrofitRoadwaysTruss-type bridgeTraffic capacityEngineering
The invention discloses a rapid unblocked urban road intersection interchange system, which comprises a bidirectional multilane east-west lane, a bidirectional multilane south-north lane and a sidewalk. Near an intersection, the lanes at the outer sides of the east-west lane and the south-north lane are small vehicle lanes; the lanes in the middle of the road are large vehicle lanes; the large vehicle lanes of the east-west lane and the south-north lane are respectively provided with a flyover which is codirectional with the lanes at two sides of the intersection; large vehicle lane traffic lights for controlling the running of the vehicles on the large vehicle lanes are arranged at the intersection; and safety islands and harbor type diversion lanes are arranged on the small vehicle lanes to ensure the traffic safety of pedestrians. In the invention, through the diversion between large vehicles and small vehicles, the traffic capacity of the intersection is effectively improved; and at the same time, the system is simple in overall structure, small in floor space, low in construction cost and suitable for the reconstruction of the existing roads.
