摘　　要：针对公交车进出港湾车站停靠不顺畅,车站几何尺寸设置与公交车运行轨迹不完全相符等问题,通过研究青岛市主干路滨海大道相同规格港湾车站公交车停靠过程,分析港湾车站车辆进出站速度、加速度、轨迹等交通要素变化特性及其相互关系,基于公交车实际进出站轨迹数据构建Gauss轨迹模型,并对港湾车站的几何设计参数进行优化。结果表明:公交车速度在车站的减速段呈现两阶段变化趋势,在加速段呈现单阶段变化;公交车进出站期间的综合加速度平稳变化,纵向加速度由负值变正值,横向加速度基本不变;轨迹模型与实际拟合轨迹相似度达到0.9913;港湾车站进出站过程中的转弯曲线半径大于现行规范中的曲线半径,在准备进出停靠段时的转弯曲线半径小于现行规范中曲线半径,加减速段长度相等。相比于传统车站设计,优化后的车站设计使公交车进站过程更加流畅,可提高公交车进站过程运行效率并节约用地面积。In view of the problems that buses do not stop smoothly in and out of the harbor station,and the geometric size of the station is not fully compatible with the trajectory of buses,the bus stopping process of the same specification of the harbor station on Binhai Avenue,a main road in Qingdao,was analyzed,and the characteristics of the change of the traffic elements such as speed,acceleration,trajectory and other traffic elements and their interrelationships were analyzed,and the Gauss trajectory model of the bus geometric design parameters were established based on the trajectory data of the buses entering and exiting the station.The Gauss trajectory model was constructed based on the actual trajectory data of buses,and the geometric design parameters of the harbor station were optimized.The results show these as follows.The speed of buses in the deceleration section of the station shows a two-stage change trend,and in the acceleration section shows a single-stage change.The comprehensive acceleration of buses during the period of entering and exiting the station changes steadily,the longitudinal acceleration is changed from negative to positive,and the transversal acceleration is basically unchanged.The trajectory model is similar to the actual fitting trajectory with the similarity degree of 0.9913;the radius of the turning curve during the process of entering and exiting the station of the harbor station is larger than that of the curve in the current specification.The radius of the turning curve in the process of entering and exiting the harbor station is larger than the radius of the curve in the current specification,the radius of the turning curve in the preparation for entering and exiting the stopping section is smaller than the radius of the curve in the current specification,and the length of the acceleration and deceleration sections is equal.Compared with the traditional station design,the optimized station design makes buses entry process smoother,improves the efficiency of the bus entry process and
