摘　　要：随着城市的发展,仅扩大交通基础设施的供应能力已无法满足城市交通需求,需结合具体区域的交通流量做出合理的道路网规划。利用四阶段法对山东省阳信县的主干路交通流量进行科学预测,分析该地交通量的发展特征,计算各路径在公路网中的重要性。结果表明,阳信县6条主干道的公路等级最低均需配置在二级以上。目前,经济发展重心位于F大道区域附近,重要度C大道最高,根据车流大小,后期在进行道路规划时需将B、E大道进行扩建,此结果可为类似工程规划提供参考。With the development of cities,only expanding the supply capacity of traffic infrastructure can no longer meet the demand of urban traffic,so it is necessary to make reasonable road network planning according to the traffic flow of specific regions.The study predicts the traffic flow of the main road in Yangxin County,Shandong Province with four-stage method,analyzes the development characteristics of the traffic volume,and calculates the importance of each route in the highway network.The results show that the lowest grade of 6 main roads in Yangxin County should be above the second grade.At present,the center of economic development is located near Avenue F,and Avenue C has the highest importance.According to the traffic flow,Avenues B and E need to be expanded in the later stage of road planning.This result can provide reference for similar project planning.
