【摘要】：区域公路网规划是公路建设重要的前期工作之一,是保障公路网有序建设的基础。区域公路网规划是从科学合理的角度,研究分析区域客货运交通现状,深度解析建设发展中存在的现状问题,根据区域经济社会发展现状预测交通增长需求,提出科学合理的区域公路网规划方案。尽管以往的理论规划模型中数理分析有着一定的合理性与规范性,但因其不能紧密的结合定性与定量分析,并且规划模型中有些参数在决策过程中无法取值,导致模型不能正确反映客观实际情况；另一方面,实践中,规划管理者采取比较直接的简单的方法,没有经过严格数学模型推理,凭经验取值,虽然有一定的适应性,但是缺乏更科学的预测分析。因此,有必要将数学模型预测的优势与实际决策的经验相结合,使区域公路网规划模型方案更科学合理。本论文以常用的区域公路网规划模型为前提,通过对区域客货交通需求预测、区域公路网的规模预测、区域公路网系统布局优化、区域公路网规划后评价等进行了研究。交通需求量是确定公路网合理规模的基础,科学合理的交通需求量预测可以后续的公路网规模确定提供有力的数据支持,同时区域公路网规模的合理配置可以适应区域交通需求发展,有利于区域经济的健康成长,公路网布局可以反映社会经济发展对交通需求及其合理配置,规划的综合评价可以反映出整体规划中各个部分衔接是否合理,是否符合区域交通发展,是否有利于区域经济发展。这四个方面构成了整个区域路网规划的关键问题。本文着重分析了以上四个方面的关键问题,最后结合南充市高坪区公路网规划建设方案进行实践分析。
[Abstract]:The planning of regional highway network is one of the important early works of highway construction and the foundation of ensuring the orderly construction of highway network. Regional highway network planning is a scientific and reasonable point of view, research and analysis of regional passenger and freight transportation status, in-depth analysis of the existing problems in the development of the construction, according to the regional economic and social development situation forecast traffic growth demand, A scientific and reasonable plan of regional highway network planning is put forward. Although mathematical analysis is reasonable and normative in previous theoretical planning models, it can not be closely combined with qualitative and quantitative analysis, and some parameters in the planning model can not be taken in the decision-making process. On the other hand, in practice, planning managers adopt a more direct and simple method, do not have strict mathematical model reasoning, value by experience, although there is a certain degree of adaptability, But there is a lack of more scientific predictive analysis. Therefore, it is necessary to combine the advantages of the mathematical model prediction with the practical decision-making experience to make the regional highway network planning model more scientific and reasonable. Based on the commonly used regional highway network planning model, this paper studies the regional passenger and freight transportation demand prediction, the regional highway network scale prediction, the regional highway network system layout optimization, the regional highway network planning post-evaluation and so on. Traffic demand is the basis for determining the reasonable scale of the highway network. Scientific and reasonable traffic demand prediction can provide strong data support for the subsequent highway network scale determination. At the same time, the rational allocation of regional highway network scale can adapt to the development of regional traffic demand, which is conducive to the healthy growth of regional economy. The layout of highway network can reflect the traffic demand and its rational allocation of social and economic development. The comprehensive evaluation of the planning can reflect whether the connection of each part of the whole plan is reasonable, whether it accords with the development of regional traffic and whether it is beneficial to the development of regional economy. These four aspects constitute the key problems of the whole regional road network planning. This paper focuses on the above four key issues, and finally carries out practical analysis combined with the highway network planning and construction plan of Gaoping District, Nanchong City.
