摘　　要：结合"南京江北新区青龙绿化带东侧片区道路工程"项目,采用"四阶段法"对研究范围内路网进行交通量预测。通过对研究区域进行交通小区划分,以Trans CAD交通规划软件为工具,对各交通小区发生及吸引量及区域交通分布进行预测,并结合南京交通数据对出行方式进行划分,得出交通量在路网中的分配结果。预测结果表明:研究范围内道路的通行能力能够满足预测年的通行需求,服务水平能够基本维持A、B级,研究区域路网规划及断面分配形式是合理、可行的。Based on＂the road project of Qinglong green belt east side area of Nanjing Jiangbei new area＂,the＂four-stage method＂is adopted to predict the traffic volume of the road network in the study area.Through the study of regional traffic area division and Trans CAD traffic planning software as the tool,thetraffic generate and attract quantity of various traffic area and traffic distribution forecast,and combining with the division of travelmode based on the Nanjing traffic data,it is concluded that the distribution results of traffic flow in road network.The prediction result shows that the research range of road capacity can satisfy the traffic demand forecast years,able to maintain class A or B basic service level,and the research regional road network planning and cross section distribution form is reasonable and feasible.
