Planting Design in front of Noise Barrier on Highway

Abstract

We studied on the planting design in front of noise barrier on highway by a psycologicul test with VTR. The tests were put into practice by VTR of landscape of highway which were composed by 8 types of model planting in front of noise barrier, and were carried out the tests for 110 persons of the subjects by the method of paired comparisons.
The results obtained from these tests ware as follows: desirable type of the planting in front of noise barrier was high rate of screening index for noise barrier by the plants. And the type such as row planting which were cutted cleanly had a tendency to get desirable valuation regardless of low rate of the screening index.
