5. CONCLUSION 
Failed places were divided into three pattems of distance parameters for the expansion, contraction and between different codes.

The cut lines are shorter than omitting parameter distance, road line are omitted also. These cases are occurred near the end of a road

In case of a cut line by assistant lines is longer than omitting distance parameter, it remain (fig.17). Or road line between omitted lines are 
also shorter than omitting distance it is moved (fig. 18).
