| 摘 要： | 本研究通过对突发事件情况下驾驶员心理与行为特性问卷调查,得到驾驶员在非常态交通环境下的行为差异和经验判断比率分布,对Gipps跟驰模型进行了改进,提出了基于最小安全跟车间距的应急疏散车辆跟驰模型.与正常交通条件下建立的跟驰模型相比,将驾驶员对突发事件的心理行为反应纳入建模过程,能更准确地反映应急疏散的交通流特征和疏散交通实际情况.

| Abstract: | Based on a questionnaire of drivers' psychological and behavioral reaction under emergency,this pa- per improved the Gipps car-following model and proposed a new emergency evacuation car-following model based on the minimum safety distance.The model contains statistical distribution of drivers' behavioral differ- entia and experiential estimate.Compared with car-following models which were established under normal traffic condition,it can be more really reflecting actual traffic state under emergency evacuation by incorporat- ing drivers' mental and behavioral reaction into model development. |
