This study investigates how commuters form accessibility perceptions and adapt travel under rainstorm warnings. An integrated Protective Action Decision Model links warning credibility, perceived risk, self-efficacy, and perceived accessibility to travel intentions, mode shifts, and departure-time choices. Analysis of 1,563 Shanghai respondents reveals systematic differences across socio-economic groups and commuting modes, highlighting the need for accessible warning services and equitable emergency transport planning.

研究概览
本研究以上海通勤者为对象，探讨暴雨预警如何通过预警可信度、风险感知、自我效能和感知可达性影响通勤决策。研究将保护行动决策模型扩展到城市交通场景，关注预警信息、个体心理判断与出行调整之间的作用链。
核心方法与发现
- 基于 1,563 份有效问卷，构建多阶段社会心理决策模型。
- 社会经济地位较低的通勤者更容易出现较低的预警信任、自我效能和感知可达性。
- 感知可达性与继续出行意愿正相关，与更换交通方式的倾向负相关；不同通勤方式的感知可达性存在显著差异。
