- Structure and the princlple of traffic flow in all 4 directions are identical.

- Off ramps are positions only on the right side of the main road, which is identical to the conventional urban highways (Riverside Highway and 88-Highway in Seoul). Drivers in urban highway naturally change lanes to the right for off ramp as they do on freeways.

- The "right off ramp - left-right merge non-stop interchange" has been designed with such drivers' tendencies in mind for application in urban highways.

  
   
   
 
   

- The second split off part of the road work to collect and distribute traffic.

- Vehicles turning left and right are split off from the main road, and they merge with the main road.

- Therefore, there is no intersecting conflict caused by flow of traffic on the main road.

  
   
   
 
   

- Required area is similar to the conventional intersection, and traffic flow is also the same (Left turn from left lane, right turn from right lane), which allows the Non-Stop Interchange to be applied in metropolitan region.

  
   
   
 
   

- It is a simple interchange to drivers.

- Both left and right turns are made from off ramp on the right, then the vehicles for left turn stay on the left, and vehicles for right turn stay on the right. This is the conventional right off ramp seen in urban highways. (88 Hightway and Riverside Highway in Seoul)

- Therefore, it is clear that drivers do not see the interchange as complex only because the overall structure is complex.
