【摘要】：为研究电动自行车在交叉口的安全特性,减少交通管理中的安全隐患,在运用TCT技术分析电动自行车交通特性的基础上,通过实地调研7个典型的四相位信号控制平面十字形交叉口,利用SPSS软件分别选取线性、多项式及指数函数对电动自行车的交通冲突调查数据进行拟合,构建了电动自行车的交叉口交通冲突模型。最后,结合所获得的交通冲突模型的各项参数,运用欧几里德贴进度评价方法,建立了交通冲突强度的评价模型,该模型可用于评估交叉口路段电动自行车的运行安全性。结果表明,散点化的比较方法不仅可以对同一交叉口的不同进(出)口道的电动自行车交通冲突强度进行分析,还能对不同交叉口同一冲突类型的安全状况进行对比评价。
[Abstract]:In order to study the safety characteristics of electric bicycle at intersection and reduce the hidden danger in traffic management, the traffic characteristics of electric bicycle are analyzed by using TCT technology. Through investigating seven typical four-phase signal control plane cross intersections, using SPSS software to select linear, polynomial and exponential function respectively to fit the traffic conflict investigation data of electric bicycle. The traffic conflict model of electric bicycle intersection is constructed. Finally, according to the parameters of the traffic conflict model, the Euclidean schedule evaluation method is used to establish the evaluation model of traffic conflict intensity. The model can be used to evaluate the safety of electric bicycle at intersections. The results show that the comparison method can not only analyze the traffic conflict intensity of electric bicycle at the same intersection, but also compare and evaluate the safety of the same conflict type at the same intersection.
