Public health crisis and risky road behaviors
利用COVID-19疫情作为自然实验，研究发现疫情带来的生命威胁风险减少了超速违规，但对非法停车等低风险违规无显著影响，表明生命威胁风险会抑制涉及生命危险的行为。
This study investigates how exposure to riskier environments influences risky road behaviors, using the COVID-19 pandemic as a natural experiment. Utilizing administrative individual traffic violation records from Taipei, where neither mandatory lockdown nor mobility restrictions were imposed, we find that pandemic-induced risk decreased speeding violations and that the effect was transitory. However, no significant changes were observed concerning violations with a minimal risk of casualties, such as illegal parking. These findings suggest that experiencing a higher level of life-threatening risk discourages risky behaviors concerning human life but has little spillover effect on those concerning only financial costs.
