Abstract : through studying the relation between urban land and layout of road network, the influences of road layout and road span on the density of road network are discussed 摘要:通过研究道路网布局与城市用地关系,探讨道路布局与道路间距对道路网密度的共同影响。
As a foundational work of highway design, the estimate and analysis of highway traffic capability, can not only define proper scale and construction mode of highway, but also provide scientific and theoretic support for layout of road net, feasibility analysis of road engineering, highway design and post estimate of highway construction, which is meaning of this subject study 公路通行能力预测分析与交通量预测分析,作为公路建设的一项基础性工作,不仅可以确定公路建设的合理规模及合理建设模式,还可为公路网规划、公路工程可行性研究、公路设计、公路建设后评估等方面提供更为科学的理论依据。
