【摘要】：为了充分发挥城市外环路对不同车流对象的服务功能,解决两互通式立交之间因间距不够引起的各种交通问题,建立了两独立互通式立交之间的最小净距模型。分析了驾驶人对道路交通信息的发现、识别、分析、判断等心理、生理反应过程,建立了驾驶人车道变换模型,根据调查资料得出运行速度与驾驶人变道转角之间的回归关系,分析了驾驶人在寻找可接受间隙期间行驶的距离,得出了两互通式立交净距的关系模型,并结合深圳外环高速公路进行了实例分析。研究结果表明:距离较近的两互通立交之间宜适当减少非必要道路交通标志的设置;双向6车道设计速度分别为100km/h和80km/h时,互通立交之间的净距不宜小于1 410m和880m;大型车比例较高或交通组织混合严重的互通式立交最小净距宜适当增加180~200m。
[Abstract]:In order to give full play to the service function of different city outer ring road traffic between the two objects, solve the interchange for various traffic problems caused by lack of space, established the model between two independent interchange of the minimum net distance. Analysis of the driver on the road traffic information discovery, identification, analysis, judgment and other psychological, physiological the reaction process, a driving lane changing model, according to the survey data of the regression relation between running speed and driving lane change angle between the analysis of drivers looking for the gap acceptance during the driving distance, the relation model of two interchange spacing, combined with the Shenzhen outer ring expressway for example the analysis results show that: two. The interchange distance should be appropriate to reduce the unnecessary road traffic signs; two-way 6 lane design speed was 100km/h and 80km/h The net distance between interchange shall not be less than 1 410m and 880m. The minimum net distance of intermodal interchange with larger proportion or larger traffic organization should be appropriately increased 180~200m..
