Table 7. Criteria for landscape conservation plan by roadscape operation element

Operating elements Criteria for landscape conservation measures
Topographical factor D 1 The structure at the end of the road should not be higher than the horizon
2 Structures higher than the horizon provide an open space for viewing the landscape.
3 If you can not do that, you can see the scenery by raising the elevation of the viewpoint
W 1 It is a principle that W doss not decrease so that Busan Port or horizon can be seen
2 If there are vertical structures on both sides of the end of the road, make sure the width of the landscape is wider than the width of road.
Vertical factor H 1 Make sure that the height of both structures on the road is not higher than the horizon.
2 A non-conforming topographic structure lowers the height to maximize the area of the background factor.
L 1 L is related to W. If the end of L is stopped before the end point of the road, W of Busan Port Landscape is increased.
