Quantified Study Of Microscopic Pedestrian Behavior Parameters In Subway

With the large-scale construction of rail transit, the number of the subway station and the passenger-flow are increasing rapidly. The behavior of passengers at the station tends to complicate, it is urgent for urban rail transit station to meet passenger travel demand and improve their operational efficiency. As the pedestrians are the main bodies in the subway, it is important to understand the pedestrians'behaviors and special characteristics and find the interaction between the pedestrian and the rail transit environment, which is the basis of "people-oriented, safe operation" in rail transit construction.The purpose of this paper is to quantizing micro-behavior parameters of the pedestrians in the subway, first analyzes the micro-behavior characteristics of the pedestrian and related the facters which can affect pedestrians'behaviors. Then according to this theory basis, the field survey has been carried out, from which we set up the parameter system that can describe pedestrians'micro-behaviors. Based on the festures of each parameter, we proposted the suitable method to quantize each parameter. Finally, according to this method, we have done the research in Xizhimen subway and then used the SPSS software to analyze the parameters which be gained from the survey. Based the analyzied results, the dynamic and static, qualitative and quantitive, contrastive methods were used together to analyze pedestrians'behaviers on the different taffic facilities.By studying, we have known the value and the distribution of pedestrian speed, the basic relationship graph between speed, volum as well as density, and the distribution in the subway space, including the horizontal pedestrian interval, the intervals between pedestrians and buildings, pedestrian features of area selection and dynamic walking characters and so on.We also find that the pedestrian behavior on the different transit facilities was more affected by other passengers and the informations about the station than the pedestrian-self influence.
