The increasing vehicle usage contributes to the rise of dustfall (DF) and suspended particles (TSP) concentration. The purpose of this study was to measure the generation of DF and TSP due to the number of vehicles (JK) and to analyze their correlation. This study was conducted on four roads,namely Ciomas, Dramaga,Sindang Barang and RE Abdullah roads. The study was conducted by installing dustfall canister for 24 hours.High volume air sampler was operated for 60 minutes simultaneously with traffic counting. The DF generation at four sampling points were less than 1 ton/km2.month. The range of TSP generation on Ciomas, Dramaga, Sindang Barang, and RE Abdullah were 57-243, 37-86, 37-177, 60-117 μg/Nm3 respectively. The significant value (α) between DF generation and JK type I in the morning was 0.037, type II in the morning was 0.002, type III in the morning was 0.031, type III was 0.001 in the night and type VI b was 0.009 The significant value between TSP generation and type III in the night was 0.002, type III total was 0.001, type VI a was 0.04 and type VI b was 0.019.
