| 摘 要： | 基于对STCA模型与F STCA模型的分析研究,结合车辆换道的实际状况,重新定义了换道风险度的概念,提出了一种更符合实际情况的改进的弹性安全换道间距规则,并进一步提出了基于该规则的双车道元胞自动机交通流模型.实验结果表明,该模型有益于提高道路资源利用率,同时在安全方面能够降低事故发生的可能性.

| Abstract: | Combined with the actual situation of the vehicle lane changing,the concept of lane changing risk is redifined based on the analysis and research of the STCA model and F-STCA model.An improved spacing rule of flexible safe lane change is presented,which is more consistent with the actual situation.Two-lane cellular automaton traffic flow model based on the rule is proposed.Experimental results show that the model is beneficial to improve the roads resource utilization,while in terms of security can reduce the possibility of accidents. |
