%X 针对信号交叉口右转车辆与非机动车冲突问题，提出右转机动车轨迹特性分析方法.对比有无干扰条件下右转车辆轨迹穿越位置分布，分析无干扰情况下轨迹的影响因素，建立轨迹模型，对模型参数进行验证.对右转机动车受同向直行非机动车干扰和受侧向直行非机动车干扰这2种情况的轨迹穿越位置进行聚类，建立有干扰条件下右转车辆平均轨迹模型.结果表明，无干扰轨迹模型与其它模型相比拟合效果要好，平均预测误差在5%以内，满足精度要求；有干扰条件轨迹模型的最大平均相对误差为7.31%.</br>Abstract: The trajectory characteristic analysis method of right turning vehicles was proposed for the conflict problem of right turning vehicle and bicycles. Trajectory density distributions at intersections with or without interference were compared. Factors affecting trajectories without interference were analyzed. The trajectory model was established and the model parameters were calibrated. Right turning vehicle with same direction straight bicycles inference and side direction straight bicycles interference trajectory position were analyzed by using clustering in order to establish average trajectory model with inference. Results show that the model without interference is better. The prediction error of the model without interference is within 5%, which meets the accuracy requirement. The prediction max error of the model with interference is 7.31%.
