The present invention is achieved through the following technical solutions above-mentioned purpose.This tunnel type interchange system, comprise existing means of transportation, A-road is center and near the two ends of intersection with the intersection, be provided with a subterranean tunnel across A-road, each of two subterranean tunnels is imported and exported all to be provided with to extend up and down accordingly and is connected with subterranean tunnel, and is connected with A-road by extending up and down.The both sides, inferior track of intersecting with A-road respectively are provided with a subterranean tunnel of crossing the intersection, and each of subterranean tunnel is imported and exported all to be provided with to extend up and down accordingly and is connected with subterranean tunnel, and are connected with time track by extending up and down.The access of extending up and down can be according to geographical condition setting on the location that allows.Below the intersection, also be provided with underground circular bicycle passage, the access of each underground circular bicycle passage is connected with the intersection of corresponding non power driven vehicle passage.
Tunnel type interchange provided by the present invention system also can be provided with the isolation strip between non power driven vehicle passage and A-road, inferior track.
The traffic rules that tunnel type interchange a kind of and recited above system matches are removed oversize vehicle or special vehicle and are still managed by existing traffic rules, and remaining traffic rules is as follows:
Motor vehicles:
The vehicle of dealing is directly kept straight on by traffic intersection on the A-road;
Come on the inferior track past vehicle by by extend up and down, subterranean tunnel keeps straight on;
The vehicle that need bend to right is turned right on the ground;
Need the vehicle of turning on the A-road left, at first will pass through the path mouth,, get final product by extending up and down to bend to right then by the opposite side of extending up and down, subterranean tunnel arrives A-road;
Need the vehicle that changes on the inferior track left, at first will bend to right, through the extending up and down of A-road, opposite side that subterranean tunnel arrives A-road, pass traffic intersection then and get final product again; It is the vehicle that turns left in the primary and secondary track one-way traffic of all instead turning right.
Non power driven vehicle:
Non power driven vehicle can directly bend to right.
Non power driven vehicle need pass through road, at first will pass through underground circular bicycle passage, and then arrives the place that will go.
The effect that the present invention is useful: compare with the means of transportation that existing traffic intersection is unimpeded, the building cost expense is low, and floor space is little, is applicable to large, medium and small road construction, and the landscape impact to the city is little simultaneously; Utilize this traffic rules, can solve intersecting of east-west direction and North and South direction; The intersection traffic congestion that cause to the left-hand bend of vehicle in four directions, the four corners of the world; Motor vehicles and non power driven vehicle and pedestrian guarantee the unimpeded of traffic in the traffic congestion that interweaves of intersection.Subterranean tunnel, extend and to be arranged on the suitable location that the geographical environment road allows up and down.
