摘　　要：为探究无信号灯控制人行横道处驾驶人礼让行人的让行决策行为,通过高空摄像头观测深圳市某商业区路段人行横道处驾驶人的让行情况,分析了驾驶人的让行决策行为与车辆、行人接近人行横道时的速度及过街行人数量的关系,建立了基于Logistic回归的驾驶人让行决策模型。通过对相关影响因素进行分析可以得出,车辆和行人接近人行横道时的速度对驾驶人的让行决策影响显著;通过拟合优度检验及预测准确性检验发现模型的拟合效果较好,模型在礼让行人背景下具有较好的适用性。In order to explore the yield decision-making behaviors of the driver at uncontrolled crosswalk in road section,the yield situation of the driver at the crosswalk in a commercial district section of Shenzhen was observed through a high-altitude camera,and the relationship between the driver’s yield decision-making behaviors and the speed of vehicles and pedestrians approaching the crosswalk and the number of pedestrians was analyzed and a driver yield decision model based on logistic regression was established. The results show that the speed of vehicles and pedestrians approaching the crosswalk has a significant impact on the driver’s yield decision. The fitting effect of the model is good,and the model has good applicability in the context of comity to pedestrians.
