Conclusions: Ambient noise levels measuredinall three cities were correlated with traffic data,
highlighting theimportance of traffic planning in mitigating noise-related heal theffects.Model
performance wassensitiveto the traffic data used as input.Future noise studies thatuse modeled noise
estimates shoulde valuate traffic data quality and should ideally in clude other factors,suchas local
roadway,building,andmeteorologicalcharacteristics.
