摘要: 研究电动车骑行者碰撞风险感知的影响因素及其各种情形下碰撞风险感知的差异. 设计基于危险情形的问卷,通过网上收集问卷获取数据,采用因子分析和Logistic模型等统计方法,对电动车骑行者碰撞风险感知进行了研究. 结果表明:驾驶技能、出行频率、年龄、冒险倾向等因素对风险感知有显著影响;电动车分别与小汽车、电动车、自行车发生碰撞时,风险感知依次下降;同一情形下,骑行者自己失误比他人失误引发的碰撞风险感知更低.Abstract: The influencing factors and the relationships among them were investigated for the crash risk perception of e-bike riders under different risk situations. An online questionnaire survey was conducted for data collection. Ordered logistic regression (OLR) and principal component analysis (PCA) were used to analyze the crash risk perception of e-bike riders. The results indicate that the crash risk perception is closely related to the factors such as driving skills, travel frequency, age and risk propensity. An e-bike rider has higher perceived risk when she/he has a conflict with a car compared with a cyclist. And the rider's risk perception declines with an individual riding error.
