The invention relates to the technical field of lane modeling, and discloses a VISSIM-based expressway virtual emergency lane modeling method, which comprises the following steps of: constructing an expressway driving rule of a virtual emergency lane; the emergency rescue time of the virtual emergency lane is divided, and the time before opening and the opening time of the virtual emergency lane are determined according to the divided emergency rescue time; constructing a virtual emergency lane control strategy model according to the pre-opening time and the opening time based on expressway driving rules; and determining the number of accident closed lanes, and dividing the virtual emergency lane control strategy model into a single-lane closed control strategy model, a double-lane closed control strategy model and a three-lane closed strategy control model according to the number of accident closed lanes. According to the method, the virtual emergency lanes are used under different traffic conditions, the effects are different, the virtual emergency lanes are started for emergency rescue, the pre-hospital rescue time can be shortened, and the accident rescue efficiency is improved.
本发明涉及车道建模技术领域,公开了一种基于VISSIM的高速公路虚拟应急车道建模方法,包括:构建虚拟应急车道的高速公路行车规则;对虚拟应急车道的紧急救援时间进行划分,并根据划分后的紧急救援时间确定虚拟应急车道开启前时间和开启时间;基于高速公路行车规则,根据开启前时间和开启时间构建虚拟应急车道控制策略模型;确定事故封闭车道数,根据事故封闭车道数将所述虚拟应急车道控制策略模型分为单车道封闭控制策略模型、双车道封闭控制策略模型和三车道封闭策略控制模型。本发明在不同交通条件下使用虚拟应急车道效果不同,开启虚拟应急车道进行紧急救援,可以缩短院前救援时间,提高事故救援效率。
