Using multi-sourced big data to correlate sleep deprivation and road traffic noise: A US county-level ecological study.

Traffic noise can contribute to variations in sleep deprivation among counties. This study suggests that policymakers could set up different noise-management strategies for relatively quiet and noisy areas (i.e., different limiting SPLs) and incorporate geo-spatial noise indicators, such as exposure population or area ratio. Furthermore, urban planners should consider urban sprawl patterns differently.
