摘　　要：兰州市为特大型带状组团城市,多年来市区交通形成了"东西拥挤,南北不畅"的交通局面,加之近年来全市机动车辆迅速增加,内、外交通联系更加繁忙,造成了现状东西向城市主干道交通量均接近饱和状态,以南山(环)路交通拥堵问题最为严重的兰工坪路段为例,提出了道路路段及硷沟沿节点的提升改造方案,解决小西湖通道与南山(环)路间的交通高效转换需求,发挥南山(环)路东西向交通疏解能力、缓解市区内西津路等东西方向城市主干路的交通压力,研究思路可为同类交通问题提供参考.Lanzhou City is a super-large banded cluster city.For many years,the urban traffic has formed a traffic situation of"east-west congestion,north-south obstruction".In addition,the rapid increase of motor vehicles in the city in recent years has made the internal and external traffic connections more busy,which causes that the current situation that the east-west urban trunk road traffic volume is nearly saturated.Taking the Langongping Road of Nanshan(Ring)Road with the most serious traffic congestion problem as an example,the upgrading reconstruction scheme of road sections and the joints along the causeway is proposed to solve the demand of efficient traffic conversion between Xiaoxihu Channel and Nanshan(Ring)Road,give play to the east-west traffic relief capacity of Nanshan(Ring)Road,and alleviate the traffic pressure of Xijin Road and the other east-west urban trunk roads in the urban area.The research idea can provide reference for similar traffic problems.
