【摘要】：选取年龄、性别、携带行李状况作为表征行人个体特征的3个要素.首先分析了这3个要素对个体空间占用和步行速度的影响,进而利用Legion仿真工具研究这三要素对行人最大通过量的作用.研究表明,年龄、性别和携带行李状况都对行人最大通过量有不同程度的影响.随着行人流中个体年龄增加,行人流的最大通过量呈下降趋势,尤其是由老年人构成的行人流,其最大通过量较青年人下降23%~30%;性别对最大通过量的影响总体较小,在10%以内;随着个体携带行李尺寸的增加,最大通过量也显著下降,由携带小行李组成的行人流其最大通过量较不携带行李约下降35%,携带中等行李较不携带行李约下降60%,携带大行李较不携带行李约下降75%.研究成果有助于加深理解行人个体特征与交通流群集移动特性的联动关系,并为由不同个体行人组成特征下的通行能力修正提供参考依据.
[Abstract]:Age, sex and baggage status were selected as three factors to characterize pedestrian's individual characteristics. Firstly, the effects of these three factors on individual space occupation and walking speed were analyzed. The effect of these three factors on the maximum pedestrian throughput is studied by using Legion simulation tool. The results show that age, sex and baggage condition all have different effects on the maximum pedestrian throughput. The maximum throughput of pedestrian flow, especially the pedestrian flow made up of the elderly, decreased 23% and 30% compared with that of the young; the influence of sex on the maximum throughput was generally less than 10%; and with the increase of the size of individual luggage, The maximum throughput also decreased significantly, The maximum throughput of pedestrian flow consisting of small baggage is about 35% lower than that of non-carrying luggage, about 60% lower than that of non-carrying baggage, and 75% lower than that of carrying large baggage. The research results are helpful for further understanding. The relationship between pedestrian characteristics and traffic flow cluster mobility, It also provides a reference for the capacity correction under the characteristics of different individual pedestrian composition.
