Large-scale analysis.
(1) BEVs emit more tire PM emissions (heavier than ICEVs) and less brake PM emissions (regenerative braking), thus necessitating a comprehensive analysis to avoid erroneous conclusions.
(2) If at least 15 % of travel is city driving, BEVs produce less non-exhaust PM emissions.
(3) For the freeway section analyzed, a traffic volume-to-capacity ratio of at least 0.25 is required for BEVs to produce less non-exhaust PM emissions.
