Abstract: The influence of the ETC vehicle proportion αE at the entrance of ETC/MTC mixed toll lane and the queuing length w of consecutively arriving ETC vehicles on the average service time tS of the mixed toll lane was analyzed. SHAKER model was modified, and the parameters of the modified SHAKER model were calibrated. A VISSIM simulation model was established to validate the validity of the modified SHAKER model. The relationship between the traffic capacity of ETC/MTC mixed toll lane and ETC vehicles proportion was analyzed and a traffic capacity estimation model for ETC/MTC mixed toll lane considering the average service time of vehicles was proposed and analyzed in comparison with the cosine function model. The results show that: the relative error ε between the calculated value of the modified SHAKER model and the simulated value of the VISSIM model for the traffic capacity of ETC/MTC mixed toll lane under different αE is less than 10%, which verifies the validity of the modified SHAKER model within a permissible range. The traffic capacity of ETC/MTC mixed toll lane increases as the ETC vehicles proportion entering the mixed lanes increases. Compared with the cosine function model, the proposed estimation model can better reflect the traffic operation characteristics of ETC/MTC mixed toll lane.

摘要: 分析了ETC/MTC混合收费车道入口ETC车辆占比αE和连续到达ETC车辆排队长度w对混合收费车道平均服务时间tS的影响;对SHAKER模型进行了修正,并对修正SHAKER模型参数进行了标定,建立VISSIM仿真模型对修正SHAKER模型的有效性进行了验证;分析了ETC/MTC混合收费车道通行能力与ETC车辆占比之间的关系,提出了考虑车辆平均服务时间的ETC/MTC混合收费车道入口通行能力估计模型,并与余弦函数模型进行了对比分析。结果表明:不同ETC车辆占比下,ETC/MTC混合收费车道入口通行能力修正SHAKER模型计算值和VISSIM模型仿真值的相对误差ε<10%,在允许范围之内,验证了修正SHAKER模型的有效性;ETC/MTC混合收费车道通行能力随着驶入混合车道ETC车辆占比的增大而增大;与余弦函数模型相比,笔者提出的估计模型更能反映ETC/MTC混合收费车道的交通运行特性。
