摘　　要：为研究公交车进出港湾式停靠站的安全性,采用多种传感器设备及摄像机采集公交车进出港湾式停靠站运动参数,分析校正车速、车速差百分比、加速度,以及与站台间距等公交车运行特征参数分布规律并建立可靠数据集.采用灰色聚类分析方法训练公交车进出港湾式停靠站安全性评价模型,根据不同灰类的取值范围划分五个安全等级,对公交车在减速进站、驻站停靠和加速出站三个阶段的安全性进行评价,并对评价结果进行验证分析.研究结果表明,公交车在0~30m的减速进站阶段总体处于较危险等级;公交车在30~120m的驻站停靠阶段以及加速出站总体处于较安全等级.In order to study the safety of bus moving in and out of harbor-shaped stop, the speed and acceleration of the bus are acquired by sensor devices and accelerometer. An investigation is carried out to analyze the distribution laws of speed, percentage of speed difference, acceleration of bus and distance between bus and station. The grey-clustering analysis method is used to build the safety eval- uation model of bus moving in and out of harbor-shaped stop. Assessment and validation of the bus safety are performed for the three phases of bus moving in and out of harbor-shaped stop： decelera- tion, stop and acceleration. Results show that it may be more dangerous for the bus in the 0~30 m deceleration phase and be safer in the 30~120 m stop phase and accelerated outbound.
