地铁站内不同类型设施结合处行人速度变化规律研究
Study on pedestrian speed change in connection areas between different facilities in subway station

以北京市海淀黄庄地铁站4号线和10号线站厅为研究对象,分析不同类型设施结合处的行人速度变化特性。通过调研,分析不同类型设施结合处行人路线的表现形式,利用非付费区内的行人走行数据,绘制、拟合速度变化曲线和速度-密度曲线,给出了行人速度在安检设备、闸机及其结合处的变化规律。结果表明:闸机前方和安检区域的速度对密度敏感区间分别为0.2~0.6人/m2和0.5~1.5人/m2,两者服务水平分别达到A级和C级时,可使行人通过速度较为理想。同时,安检设备与闸机连续配置时,安检设备可为闸机提供行人缓冲作用。研究成果可为设施设备配置及行人仿真提供依据。
In this paper, the concourses of line 4 and line 10 in Haidian Huangzhuang subway station were chosen as research objects, and the pedestrian speed features in the connection areas with different types of facilities were focused on. Traveling route modes were analyzed through survey. The of curves of the speed and speed-density were drawn and fitted using the data of pedestrian in non-paying areas to show the feature of the speed change in security inspection equipment and gates. The results show that the speed-sensitive intervals of density are 0.2-0.6 person/m2 in front of gates and 0.5-1.5 person/m2 at security inspection equipment,respectively. The pedestrian speed will be acceptable when the service level reaches A at the gates and C at the security equipment, respectively. Besides, when the security inspection equipment and gates are located successively, the security inspection equipment can reduce the pedestrian arriving rate at the gates. The results could provide guidance for facilities layout and pedestrian simulation
