Transport interchanges building proposed design can be implemented without interrupting the existing traffic flows. Driving by the circular overpass allows timely correcting of drivers' mistakes, especially in case of low-skilled drivers or in case of bushed drivers. Driving on the circular overpass in any options of traffic interchanges represent familiar and typical actions, reducing the probability of errors and preventing accidents. At the moment of entering the circular overpass there is no need to look in the rear view mirror as an automobile is entering the lane not occupied by other vehicles, because their intention is to drive to the other edge of the lane to exit from the circular overpass.

A diverse range of applications of traffic interchanges is offered to link them to the different local features. Claimed traffic interchanges provide non-stop traffic, increasing its capacity and reducing the actual time of internal combustion engine working in the speed regime changing conditions integrally reducing fuel consumption and emissions (improving the local environmental conditions).

The essence of proposed options of the traffic interchange is in a smooth change of lanes after standard entering to the circular overpass (rule of circular flow) following by the centripetal movement toward exits within the circle, resembling "funnel" movement or vice versa when it is with entering through the inner edge of the circular overpass with the centrifugal movement toward exits from the outer edge, i.e. "funnel" movement towards exiting i.e. "centrifugal" movement towards exiting, avoiding interference of the traffic flows. Rules of circular driving are recognized as optimal by experts in the most megalopolis with hard traffic. One third of automobile road accidents happens on the road crossing points. The claimed invention and provided technical solutions of the traffic interchanges minimize accidents on the roads by using the non-stop traffic where traffic flows don't intersect. As a rule, the exiting points should be situated before the entering points. This requirement is met and is common for the claims. An application of traffic interchanges in accordance with the proposed options allows changing the driving direction without any interfering flows at the conflict points. Proposed traffic interchange (options) can be placed on any level of crossing highways, namely, below the roads, between the roads, under the roads (below ground level or in tunnels). Preferably, the construction of such traffic interchanges should be at intersections with a capacity of over one thousand vehicles per hour, driving in all directions. Options of the traffic interchange allow organizing the transport hub for public transport passengers with pedestrian crossings in areas linked to main roads and not outside of the interchanges. It reduces the cost of construction because there is no need to build underground or over ground pedestrian crossings. Entering and exiting ramps to the circular overpass are assumed to constitute curves with a radius close to the radius of the circular overpass. Light metal frames in conjunction with point supports for the closed circular traffic allow to create the most robust and reliable structure.
