摘要
提出了2种造价经济、施工方案可行的无阻滞交叉口设计方案。将双支交叉小型跨线桥与变速车道移位斜交相结合的设计方案应用于交通流量较大的交叉口,将远引式左转与上跨高架桥相结合的设计方案应用于流量较小的交叉口,并进行交通仿真验证。结果表明:在不同交通流量负荷条件下使用相应设计方案后,可以大幅度提高交叉口的通行能力,降低干道路网的延误率。
The design schemes of two types of no blocking intersection were introduced, which are both economical and feasible for construction The combination design of double cross small flyover and speed change lane shift skew was applied to higher flow rate traffic intersection. The design scheme of the combination of the far leading left turn and the overhead bridge was ap-plied to the intersection with lower flow rate. And these two types of schemes were carried out with traffic simulation and verifi-cation. The result indicated that under different traffic load conditions will improve the traffic capacity of the intersection by using the corresponding design and reduce the delay rate of the trunk road network.
