摘　　要：当城市主干道及辅道并行路段存在多处大型特殊车辆进出需求情况下,为确定道路侧分带开口型式选择,通过收集沿线居民出行需求,并结合道路等级、道路侧分带及辅道宽度条件、行车路侧干扰性、交通组织流畅度等方面,对道路路侧侧分带开口间距、冲突点数量、车辆行驶轨迹及交通组织等方面按不同方案进行充分论证分析。结果表明:1)参照城市快速路要求进行侧分带开口的交通组织最为理想,按照城市主干道要求开口次之,以居民需求开口最差;2)根据Auto TURN轨迹模拟分析,在通行大型特殊车辆的情况下,主干道与辅道及辅道与道路两侧建筑物出入口需进行展宽处理,以满足转弯需求;3)设计阶段应根据项目的实际情况动态调整,选择合理可行的实施方案,确保项目能顺利落地。When there is a demand for multiple large special vehicles to enter and exit on the parallel sections of the main and auxiliary roads in the city,in order to determine the type of opening on the side of the road,by collecting the travel needs of residents along the route,and combining the road grade,road side zoning and auxiliary road width conditions,road side interference,traffic organization smoothness,etc.,a comprehensive demonstration and analysis will be conducted on the road side zoning opening spacing,number of conflict points,vehicle driving trajectory,and traffic organization according to different schemes.The results show that:1)Referring to the requirements of urban expressways for traffic organization with side strip openings is the most ideal,followed by opening according to the requirements of urban main roads,and the opening according to the needs of residents is the worst;2)According to the Auto TURN trajectory simulation analysis,in the case of large special vehicles passing through,the entrances and exits of the main and auxiliary roads,as well as the buildings on both sides of the auxiliary roads,need to be widened to meet the turning requirements;3)During the design phase,dynamic adjustments should be made based on the actual situation of the project,and a reasonable and feasible implementation plan should be selected to ensure the smooth implementation of the project.
