摘要:

为减少电动自行车违规行为,提升交叉口安全管理水平,从冲突对象数量和运动状态2个方面选择后侵入时间(PET)、交通冲突时间(TTC)和安全减速度(DST)等指标,采用k均值聚类将违规骑行电动自行车引起的交通冲突严重程度划分为一般、严重和潜在冲突3类。并采用泊松函数拟合冲突频数分布特征,引入随机变量刻画交通冲突之间异质性的混合效应,构建基于广义线性混合模型(GLMM)的违规骑行电动自行车交通冲突预测模型,预测多等级交通冲突频次。结合视频调查得到的996起电动自行车交通冲突数据进行实证分析。结果表明:不同严重程度的电动自行车交通冲突占比与违规行为类型无关;构建的GLMM模型对违规骑行电动自行车交通冲突数据的拟合优于广义线性模型(GLM)方法,且对一般冲突频数的预测效果最好;通过加强管理电动自行车占用机动车道和越线等待行为、增设协管员和调整信号相位能有效降低违规骑行电动自行车冲突发生率。

Abstract:

Traffic conflicts caused by illegal riding of e-bikes are a great challenge and negative impact on the safety management and operation efficiency of signalized intersections. In this paper, three indexes including post-encroachment time (PET), time to collision (TTC) and deceleration-to-safety time (DST) were selected from the two aspects of the number of collision objects and motion state. The k-means clustering was adopted to divide the severity of traffic collisions caused by illegal riding of e-bikes into three categories: general, serious and potential collision. Secondly, the Poisson function was used to fit the distribution characteristics of conflict frequency, random variables were introduced to describe the mixed effects of heterogeneity among traffic conflicts, and a prediction model for traffic conflicts of illegal riding e-bikes based on GLMM was built to predict the frequency of traffic conflicts of multi-grade severity. Combined with the data of 996 e-bike traffic conflicts obtained by video investigation, the empirical study shows that the proportion of e-bike traffic conflicts with different severity has nothing to do with the types of violations. The constructed GLMM model is better than generalized linear model (GLM) in fitting the traffic conflict data of illegal cycling e-bikes, and has the best prediction effect on the common conflict frequency. By strengthening the management of e-bike occupation of motor vehicle lanes and the waiting behavior of crossing the line, adding escort officers and adjusting the signal phase, the incidence rate of e-bike conflict can be reduced.

Key words: e-bikes, generalized linear mixed model (GLMM), violated behaviors, severity level, conflict prediction
