摘　　要：在分析道路衔接的构造特性及交通流特性基础上,采用回归分析技术及可接受间隙理论,综合考虑车辆驶离匝道后汇入地面道路、完成交织运行、顺利进入交叉口的运行过程,从系统的角度构建下匝道衔接道路的通行能力模型。结合实际调查数据,通过与V iss im仿真值进行比较,对模型的正确性进行了验证,结果表明模型是有效的。First, the framework features and traffic flow features of the off-ramp joint were analyzed. Regression analysis and gap acceptance theory were employed to form a capacity model of the off-ramp joint. The traffic maneuver was considered while the off-ramp turned trying to cross at the next downstream intersection at the off-ramp joint. The model was verified to be feasible through the comparison with the simulation results of VISSIM. Thus, it provides theoretical basis for analyzing congestion and giving the corresponding measures.
