长坡路与贵黄高速交叉口交通分析及渠化设计探索

Traffic Analysis and Channelization Design of Changpo Road and Guihuang Expressway Intersection

不规则交叉口是城市交通的瓶颈,合理的渠化设计可以提升不规则交叉口通行能力和安全状况。以贵阳市长坡路与贵黄高速不规则立体交叉口为实例进行不规则交叉口交通优化设计,根据相关渠化方案,设计原则提出针对长坡路的交通改善方案,对长坡路进行交通分析及渠化设计,提高该交叉口的通行效率与安全,最后进行渠化方案评价。渠化后的交叉口通行能力提高。

Irregular intersections are regarded as the bottleneck of urban traffic,but reasonable channelization design can improve the capacity and safety of irregular intersection.Analyzed the treatment methods of traffic design at irregular intersection,taking the three-dimensional intersection of Guiyang Changpo Road and Guiyang-Huangping County expressway as an example,according to the main principles of canalization design,traffic improvement schemes for long slope road are proposed to improve the traffic efficiency and safety of intersections and traffic analysis and canalization design are carried out for intersections.Finally,canalization schemes are evaluate.Therefore,the traffic capacity of intersections has been improved.
