摘　　要：文中在对多车道高速公路出口分流区交通流特性分析和客货分离理论的基础上,提出了一种双出口式的客货分离出口分流区设置方法,完成了区域内部交通运行状态的分析,结合交通运动学理论建立了同分带开口、分车型减速车道长度、双出口间距长度模型,采用对比分析的方法构建了vissim仿真实验对所提方法合理性和适用性进行了验证.结果表明:本文所提出的硬隔离双出口方案,对标单出口方案的优势主要体现于能承担更大的分流交通量,在分流比和大型车比例较大的情况下降低延误在10%~20%,提升平均行程速度在5%~15%,减少交通冲突率在5%~40%.Based on the analysis of traffic flow characteristics and the theory of passenger and cargo separation in the exit diversion area of multi-lane expressway,a method of setting the exit diversion area of passenger and cargo separation with double exits was put forward,and the analysis of traffic operation status in the area was completed.Combined with the traffic kinematics theory,the models of the same-lane opening,the length of deceleration lane of different vehicles and the length of the gap between two exits were established,and the vissim simulation experiment was built by comparative analysis method to verify the rationality and applicability of the proposed method.The results show that the advantages of the hard-isolated dual-exit scheme compared with the standard single-exit scheme mainly lie in that it can bear more diverted traffic,reduce the delay by 10%~20%,improve the average travel speed by 5%~15%,and reduce the traffic conflict rate by 5%~40%.
