This paper presents a highway traffic forecasting model, or "Line,Plane, Space" method, and introduces the characteristics and calculations of the highway traffic network. Then it discusses the layout, the optimization and arrangement of the technical grade composition of the highway network. 本文以干线公路网为研究对象,首先建立了公路交通预测模型,提出了“线、面、体”预测方法.其次介绍了公路网主要道路与交通流特征的概念及其计算公式,并据此探讨了干线公路网等级结构优化问题及其求解方法,以及公路网等级结构配置问题。最后提出了公路网交通评价的指标及方法。对于主要的理论方法,编制了计算机软件,应用该软件对某省干线公路网进行了计算,取得了较为满意的结果。 Based on the requirement of the management of Sanxia Project HighwayTraffic Network, the Sanxia Project Highway Traffic Management Information System isdesigned. The system is developed on GIStechnique, builds the spatial database and attribute database of Sanxia Project Highway Traffic Network, develops many functionmoulds such as the information query of information of highway traffic network, the comprehensive analysis etc. The system can also perform multiple analysis on attributedatabase and spatial...

The thesis, based on the analysis of the relationship between the city development and traffic development, makes an exposition on the characteristics and laws that the highway traffic network leads the city space development from three aspects: the role that the highway plays in the city space development, the influence that the highway on the city layout and space developing and the highway network layout leading the city space developing characteristics; following the index selection principle of representativeness, comparableness and operativeness, makes selection on the evaluation index of network adaptability and illustrates the definition and quantification analysis method of relevant index. At last taking example of Suqian highway network in 2000, the thesis makes inspection on the scientificness, reliability and applicability of the Evaluation method and puts forward relevant improvement suggestions on the basis of analyzing the calculation result. 本文在城镇发展与交通发展关系分析基础上,从公路在城镇空间发展中的作用、公路对城镇布局和空间拓展的影响以及公路网络布局引导城镇空间发展特点三方面入手阐述了公路交通网络引导城镇空间发展的特点与规律;遵循指标的选取具有代表性、可比性、可操作性的原则,对网络适应性评价指标进行了选取,并阐述了相应指标的定义及量化分析方法。最后以宿迁市2000年现状公路网为例,对评价方法的科学性、可靠性与实用性进行了验证,并在对计算结果分析基础上提出了相应的改进建议。
