摘　　要：针对交叉口交通控制模型在理论研究中效果明显,在实际应用时经常出现模型失配的问题,本文提出交通控制模型的模型退化概念。构建具有多控制变量的交叉口交通控制模型,分析导致模型退化的原因并给出退化路径,利用OSP(Open Simulation Platform)在线交通仿真平台对交通控制模型退化的各阶段模型的典型控制策略进行对比分析。结果显示:在应对过饱和状态时,先进的控制策略能够更好地响应交叉口通行能力系数的变化;随着模型退化加剧,所匹配的控制策略对交叉口的控制效果逐步降低,证明模型退化概念的可行性和有效性。Though the intersection signal control model performs well in theory,it often has a model mismatch problem in practice.In response to this problem,we propose the concept of model degradation of the signal control model.An intersection signal control model with multiple control variables is first developed.The degraded path is then proposed based on the causal analysis of model degradation.Finally,the comparisons between the typical control strategies of each stage in the signal control model degradation are developed by using an online traffic simulation platform.The results show that the advanced control strategies can better respond to the changes in the intersection capacity coefficient when the intersection is oversaturated.However,with the aggravation of model degradation,the control effect of the intersection gradually decreases,which shows the feasibility and effectiveness of the model degradation concept proposed in this paper.
