Near-road measurements for nitrogen dioxide (NO2) using passive air samplers were collected weekly in traffic exposure zones (TEZs) in the Research Triangle area of North Carolina (USA) during Fall 2014. Land use regression (LUR) analysis and pairwise comparisons of TEZs showed NO2 concentrations were associated with TEZs. Greater NO2 levels occurred in delay, high volume, and bus route sections versus higher signal light density, urbanized, and remainder of study areas. Comparison of near-road passively sampled NO2 concentrations by TEZ agreed with previous real-time on-road comparisons for NO2 in these TEZs.
