为提升乘客乘坐舒适性，基于公交运动三轴加速度数据，采用有序Logistic回归分析探究了单向车道数、公交站点数、信号控制交叉口数、有无机非隔离带、有无公交专用道等外部环境因素对公交振动舒适性的影响，并采用二元Logistic回归分析首次量化评价了站台类型对舒适性的影响程度。分析发现：无机非隔离带的非常不舒适概率是有机非隔离带的3.5倍；随着单向车道数的增加，计权加速度均值降低了18%，舒适性显著降低；公交车在停靠港湾式站台时极不舒适概率是其在直线式站台的24.6倍。研究表明，设置机非隔离带可显著降低非机动车及行人对公交的影响，优化公交运行效率；增加单向车道数能够减少因频繁变道导致的交通延误，进而提升舒适性；特别是港湾式站台给乘客带来了极不舒适的乘坐体验，减少港湾式站台的设立是提升公交服务质量、增强公交吸引力的关键。

In order to enhance passenger ride comfort, based on the three-axis acceleration data of bus movement, the effects of external environmental factors such as the number of one-way lanes, the number of bus stops, the number of signal-controlled intersections, the presence or absence of motor-nonmotor separation barrier, and the presence or absence of bus-only lanes on the vibration comfort of buses were explored by using ordered Logistic regression, and the influence degree of the type of station on the comfort was quantitatively evaluated for the first time by using binary Logistic regression. The analysis finds that: the probability of experiencing very uncomfortable conditions on roads without a barrier separating motor vehicle lanes from non-motorized lanes is 3.5 times higher than on roads with such a barrier; The mean weighted acceleration has decreased by 18% with the increase in the number of unidirectional lanes, which significantly reduces the comfort of ride; The probability of being very uncomfortable for buses stopping at a harbor-type platform is 24.6 times higher than for buses stopping at a straight-type platform. The study shows that the installation of barriers separating motor vehicle lanes from non-motorized lanes can significantly reduce the impact of non-motorized vehicles and pedestrians on buses and optimize the efficiency of bus operation; Increasing the number of unidirectional lanes can reduce traffic delays due to frequent lane changes, and thus improve the comfort of ride; In particular, it should be noted that harbor-type platforms bring passengers a very uncomfortable riding experience, and reducing the establishment of harbor-type platforms is the key to improving the quality of bus service and enhancing the attractiveness of buses.
