Public attitude, behavior, and social norm changes over six months with the NYC congestion charge
摘要
In January 2025, New York City implemented America’s first congestion charge. In a six-month survey, before (n = 1417), during (n = 1031), and after (n = 603), the majority support was steady. Supporters’ attitudes strengthened gradually, while opponents’ attitudes peaked at implementation. Opponents engaged in fewer opposing behaviors than supporters engaged in supportive ones. Car-restriction norms grew stronger inside the tolls. Although effects were modest, this underscores how policy implementation may shift public attitudes and norms.
