The invention discloses a road impedance function parameter calibration method in a multi-vehicle mixed driving environment. The method comprises the following steps: acquiring traffic flow environment data of a target road section; according to the traffic flow environment data, road section traffic capacity values in the pure vehicle type environment are calculated; obtaining traffic flow record data of the target road section in the whole time period; carrying out optimization processing on the traffic flow record data, wherein the optimization processing comprises abnormal sample elimination, traffic state discrimination, and mixed traffic flow calculation and correction; and completing road impedance function parameter calibration by adopting a least square method. According to the method, the defects in the prior art are overcome, and the effectiveness of an existing road impedance function parameter calibration method is improved.

    本发明公开了一种多车种混行环境下的道路阻抗函数参数标定方法,该方法包括以下步骤:获取目标路段的交通流环境数据;根据交通流环境数据分别计算纯车种环境下的路段通行能力值;获取目标路段全时段内的车流记录数据;优化处理车流记录数据,包括异常样本剔除、交通状态判别、计算和修正混合交通流量;采用最小二乘法完成道路阻抗函数参数标定。本发明补充了现有技术中的不足,提高了现有道路阻抗函数参数标定方法的有效性。
