AB  - This study used a scanning mobility particle sizer (SMPS) to measure and 
      categorize submicron atmospheric particles in the 14-737-nm size range for 
      ambient and urban roadside air and for air in the Hsuehshan Tunnel (12.9 km), 
      Taiwan. Principal component analysis, traffic flow, and particle size 
      distributions were used to identify the emission characteristics of light-duty 
      vehicles (LDV) with the SMPS data. In the Hsuehshan Tunnel, the particle size 
      from the majority of emissions discharged by LDV is approximately 20-60 nm, and 
      the maximum particle number can reach up to 2.5 x 10(5). In contrast, submicron 
      particle size distribution for urban roadsides is mostly 14-200 nm, and the 
      maximum particle number is approximately 4 x 10(4) with the particle number for 
      most particle sizes being below 1,200. The submicron particle size distribution 
      at the ambient air station was unimodal with a mode sizes at 30-50 nm with the 
      maximum particle number of 3,000.
