摘要
为研究实际高速路激进型驾驶行为对交通流的影响,对NGSIM中80号州际公路(I80)数据进行分析。通过对数据中车头间距、车辆换道等参数的分析,提出了针对激进型驾驶行为的换道模型。运用元胞自动机,在单车道VDR模型和双车道STCA模型基础之上采用动态换道概率并建立了ISTCA模型。通过对不同道路密度条件下换道行为进行模拟仿真,并与STCA模型进行对比分析。仿真分析表明,在一定密度范围内,ISTCA模型能有效提高道路的通行能力。
In order to research the effect of aggressive driving behavior on highway traffic flow,analysis the realistic data from NGSIM I80（Interstate 80）. Come up with an aggressive driving behavior model by the analysis of Space Headway,Lane-changes and other parameters from the data. Modeling ISTCAmodel with dynamic lane-changing probability based on single lane model VDR and two lanes model STCA through cellular automata. The driving behavior in different density is analyzed compare with STCA model. As analysis of simulation delays,with a certain amount of density,ISTCA model can improved capacity effectively.
