For example, the present invention arranges respectively a bicycle of going up earlier the aerial layer viaduct on (X) positive and negative direction road Lead-in wire bridge in road is crossed over the outside, coaxial left arterial highway and is formed the reverse driving track, solved the upper right arterial highway of the positive and negative direction of (X) axle (E), (G) need on to turn left and be bent to the problem of the Vehicle Driving Cycle that (Y) direction of principal axis goes; The bicycle road of rear upper aerial layer viaduct is set again The lead-in wire bridge, having solved needs on the upper right arterial highway of the positive and negative direction of (X) axle (E), (G) to turn right is bent to (Y) direction of principal axis and goes The problem of Vehicle Driving Cycle; In the positive and negative direction of (Y) axle three tracks lead-in wire bridge is set earlier, behind the aerial layer viaduct, for straight line Separate with the viaduct track of travelling for right-hand bend in the viaduct track of travelling, turning left to travel, and it is positive and negative to have solved (Y) axle Vehicle on the right arterial highway of direction (A), (C) and descend earlier viaduct need to enter the positive and negative direction of (Y) axle and do the intersection in track etc. Problems. The present invention to the track of all directions turn, arranged in a crossed manner complete, rationally symmetrical, do not have the direct crosspoint of driving, No closed circuit, the car shunt volume is big and rapidly, the efficient height has been avoided the congested with cars phenomenon effectively.
3, effectively utilize crossroad and road Land Utilization. The design provides a kind of and has built viaduct at road Scheme does not have loop ramp, has saved to the utmost the floor space problem of the road of central area, crossroad, has solved Existing traffic system particularly crossing, center causes the low problem of path area utilization rate because traffic lights are set, and is rough according to me Estimate that city crossroad center path area is person more than 900 square metres, the crossroad just has the wide above person in 6 * 7 tracks Can build such viaduct, can set up 5000 to 10000 square metres (to remove at surface road under the viaduct simultaneously Viaduct post, pedestrian road, greenbelt are outer) parking lot or commercial location, fully improved making of the shared soil of urban road Use efficient.
4, be conducive to integrate the urban transportation order. The present invention makes way for pedestrian, non power driven vehicle to the T-shaped road junction surface road, no But be practically applicable to the national conditions that I cross bicycle big country, also be conducive to develop green traffic---such as electric motor car, reduce city locomotive tail The air pollution that gas causes. Simultaneously, owing to the revolution track, be convenient to the single file that the city is transformed into small streets motor vehicles The urban transportation order can be integrated thus in the track comprehensively.
5, by explanation two, can greatly simplify the overpass bridge project organization, save a large amount of construction costs, though building the land area of parking lot or commercial location on the ground floor road has dwindled, but can prolong aerial layer overpass bridge construction length on (Y) direction of principal axis, remedy this shortcoming---and build the parking lot with in the city, needing to look in addition, utilizing advantage of the present invention to solve city driving problem difficult, parking difficulty should be the development trend of future city road construction.
