There are various road traffic noise assessment methods in Korea. However, the current road traffic noise assessment method does not accurately reflect noise in areas where continuous traffic flows, such as highways. In the United States, the Continuous-Flow Traffic Time-Integrated Method (CTIM) exists, which is the road traffic noise assessment methods to measure the influence of road surfaces on highway traffic noise at a specific site. CTIM captures the sound from existing traffic for all vehicles on all roadway lanes. also include propagation effects over the roadway and adjacent terrain to the nearby measurement location.
In this paper, analyze and compare the characteristics of Korean standard traffic noise measurement method and CTIM.
