摘要: 研究速度协调与临时使用路肩两种主动交通管理措施的集成优化。基于道路上的海量检测数据筛选出研究时段内的交通崩溃现象,分析路肩车道流量对交通崩溃概率的影响,利用路肩车道流量、基本行车道流量、出入口匝道流量建立高速公路主线基本段、入口匝道汇流段、出口匝道分流段的非参数交通崩溃概率模型及Logistic概率模型,并利用实际的检测数据进行拟合,提出以总路段交通崩溃概率之和最小为优化目标的模型进行速度协调与临时使用路肩集成优化,并以英国M42高速公路进行实例仿真,结果显示该方法具有一定的应用价值。

Abstract: We have a study on hard shoulder running (HSR) combined with speed harmonization. The breakdown events were screened out during the study period from massive detector data. The impact of hard shoulder volume on breakdown probabilities was analyzed. The nonparametric breakdown probabilities distribution model and logistic regression model were put forward based on highway mainline traffic volume, hard shoulder volume and ramp volume from the study case which was divided into three factors-basic segment, on-ramp merging segment and off-ramp diverging segment. The speed harmonization and HSR were optimized through reducing the traffic breakdown probabilities of a congested traffic network. The strategies were tested on M42 highway in the United Kingdom, which shows that the method has practical application value.

Key words: active traffic management, hard shoulder running, speed harmonization, METANET traffic flow model
