摘要:

为了减少双车道公路交通事故数量、提高运行效率,提出了双车道公路设置附加车道的理念,基于试验数据开展了双车道公路设置附加车道的交通量条件研究.通过双车道公路实车实验获得的基础数据,建立了双车道公路交通冲突时间与交通量、设计速度的关系模型.依据构建的模型,给出了对应不同设计速度的双车道公路设置附加车道的交通量条件.基于样本数据的研究结果表明:设计速度为80 km/h的双车道公路,单向交通量大于495 veh/h/ln 时,应设置附加车道;设计速度为60 km/h 的双车道公路,单向交通量大于454 veh/h/ln,应设置附加车道;设计速度为40 km/h 及以下的双车道公路,设置附加车道效益不明显,不建议设置.

Abstract:

In order to reduce traffic accidents and improve operating efficiency on two-lane highway, the concept of setting auxiliary lane on two- lane highway is proposed, and the traffic volume conditions of setting up auxiliary lane on two-lane highway are studied. Data is obtained through vehicle experiment on two-lane highway, and the relational model among the traffic conflict time, the traffic volume and the design speed on two-lane highway is established. Based on the established model, the different conditions of traffic volume of setting auxiliary lane on two-lane highway are obtained. It shows that auxiliary lane should be set when traffic volume is more than 495 veh/h/ln and 454 veh/h/ln respectively on two-lane highway with the design speed of 80 km/h and 60km/h. It isn’t recommend to set auxiliary lane on two-lane highway with the design speed of 40 km/h because the benefit is not obvious.

Key words: traffic engineering, setting condition, linear regression, auxiliary lane, traffic volume
