城市灯控平面交叉口慢行交通时空违章特征研究

在南京市内4个典型交叉口调查数据的基础上,通过对4 000多个行人样本数据和相应交叉口不同时间段的自行车违章数据的统计分析,得出了慢行交通的时空违章特征.行人个体违章在时空违章上有不同的表现形式,在不同交叉口存在很大的差异性;行人的违章行为与性别无关,与年龄有关,少年的违章比例最低.由于交叉口断面形式、信号配时、运行秩序、交通管制、周边环境等方面的因素,自行车的行驶方向平均违章率和违章性质平均违章率在不同交叉口存在很大的差异性.针对慢行交通违章者安全意识淡薄且违章成本较低、交叉口的设计不合理等原因,提出相应的预防和纠正违章的建议和措施.

Slow Traffic Peccancy Character for Urban Signal Intersection

It has been drawn out from statistical analysis on 4000 sample data of the peccancy of passerby at different intersection from the four model intersection in Nanjing that there is different behave forms in time and space for passby peccancy and great difference at each crossings.It relates to passerby age,but not to sex,e.g.the peccancy rate of teen-age is the lowest.There is great difference in peccancy of run way and behavior property by analysis on differ time sect bicycle date,which is related to some factors,such as road cross-section,traffic control,run order and surrounding environment.According to the main reason of slow traffic peccancy behavior,i.e.the actor′s dim safety consciousness,low cost of peccany,srrationali intersecton design,corresponding suggestions and measures to prevent and correct traffic peccancy are proposed.The behavior character of slow traffic peccancy on the city′s signal intersection would be a good reference for solving the urban signal intersection mixed traffic problems.
