Public transit reduces traffic congestion.

Is it true that public transit reduces traffic congestion?

Partly. Several peer-reviewed strike studies (Los Angeles 2003, Rome 2019) and reference works indicate that public transit supplies congestion relief, though each covers a single city or lists transit among mitigation options. One simulation study finds that reduced transit use during pandemic social distancing worsened congestion in Manhattan, so the evidence is partial and points both ways.
