Abstract:

In order to study non-motorized illegal crossing behavior at signalized intersections, seven signal intersections in Xi'an were selected, and the data were captured by video capture. The concepts and metrics of complex networks are used to analyze the structural characteristics and evolution rules of non-motorized network. The non-motorized network at the intersection is established. Based on the basic idea of SI model, the propagation model of non-motorized crossing behavior is put forward. And through python program simulation analysis, the trend of non-motorized illegal crossings are obtained in different network structures and different spreading rates. The results show that: as the waiting time increases, more cyclists will join in the violation crossing once a cyclist crosses on red firstly; electric bicycles have higher in-degree and out-degree than bicycles; and non-motorized violations increase as the spreading rate and the non-motorized traffic increase.

Key words: urban traffic, illegal crossing behavior, complex network method, non-motor vehicle, SI model, herd mentality, signalized intersection

摘要:

为研究信号交叉口非机动车违规过街行为,选取西安市的7个信号交叉口,通过视频拍摄获取资料,应用复杂网络来分析非机动车网络的结构特征和演化规律.建立了交叉口非机动车网络,基于SI模型的基本思想,提出了非机动车违规过街行为的传播模型.并通过python程序进行模拟分析,在不同的网络结构和不同的传播率下,获取了非机动车违规过街的行为趋势.结果表明:随着等待时间的增加,一旦有骑行者闯红灯,更多的骑行者将加入到违规过街的行列;在内向度和外向度方面,电动自行车均高于普通自行车;非机动车违规行为随着传播率及非机动车流量的增加而增加.
