摘　　要：在城市群公路网布局研究中,为了加强交通基础设施建设,促进人、物、资金合理流通,加快城市群的协调发展,针对城市群公路网的区位特性,运用交通区位理论,建立了基于遗传算法的公路网布局双层规划模型,提出了节点重要度法与交通区位线法融为一体的城市群公路网规划布局新方法。该方法对于进行城市群公路网的合理布局,推动区域经济社会快速健康协调发展具有一定现实意义。In order to strengthen the city gToups＇ coordinated development of transport infrastructure and to promote human, goods and capital of city groups flowing reasonable exchanges in the highway network layout of the city groups study, the area location character of city groups was analyzed with the area location theory. The double - decker planning model of layout highway network was established based on genetic algorithm and the newmethod of highway network layout that combined the theory was given for the node important degTee and area location. This method can make a rational plan for the highway network layout of the city groups and can promote to realize the coordinated, rapid and healthy development of regional economy and society, so it is of practical significance.
