PURPOSES : The computational fluid dynamics of flow and fine particles in a road were set to determine the insert flow and occurrence characteristics.METHODS: The road extension was 100 m with two lanes. A one-ton truck traveled a 50-m distance. After a noise barrier was installed on one side of the road, the flow and a collision analysis were tested.RESULTS: The flow that occurred was 5 m/s beside the vehicle, and fine particulate was 5.0×102 μg/m3 after 20 m from the exhaust vent.CONCLUSIONS: After a collision analysis of the fine particulate on the noise barrier to find the most suitable position of the filter panel in height, the bottom 1 m was the most optimum position because 88.1% of the distribution was concentrated there.
