*1 The cloverleaf in traffic characteristics is not comparable with the other interchanges.
The calculation is added as the simplest version of the interchange
*2 The outer edge of the road is taken into account
*3 The road straight on the upper level can also be carried out mostly after the embankments instead of the overpasses.
In this case, we have overpasses in the length of 200m and the embankments in the length of 420m.
