广州地铁杨箕站通道服务水平分级方法研究

Classification of Passage LOS at Guangzhou Metro Yangji Station

针对城市轨道交通车站通道设施服务水平分级问题,提出了一种基于高斯混合模型的服务水平分级方法。该方法以通道人均占用空间为分级标准,基于实时客流的流量、密度和速度,建立高斯混合模型,利用模型对通道设施服务水平进行分级。以广州地铁杨箕站的实际客流数据对模型进行验证,证明了模型的实用性,为车站通道设施服务水平划分及客流引导提供了依据。

In order to classify the level of service(LOS)for urban rail transit station passage facilities,a classification method based on Gaussian mixture model is proposed.In which the per capita space of passages is taken as the classification standard,and a Gaussian mixture model of LOS for passage facilities is established based on the passenger flow,density,and speed in time.The model is used to classify the passage LOS.Finally,the actual data of passenger flow at Guangzhou metro Yangji Station is used to verify the model,and confirm the practicability of the model.This research provides a basis for the classification of LOS and passenger flow guidance of the station passage facilities.
