文档介绍：农村公路网规划研究——以通州区乡村公路网规划为例摘要农村公路网是整体路网的重要组成部分。作为农村地区最重要的交通基础设施,农村公路对促进地区经济和社会发展具有极其重要的作用。近年来,我国经济快速发展,但是农村地区的公路建设却相对缓慢,并成为制约农村发展的主要因素。因此,推进和加强农村公路网规划的研究具有重要的现实意义。本文以北京市通州区为研究实例,在全面分析当地交通及路网特点的基础上,阐述了农村公路网规划中应该遵循的基本原则及基本框架。之后,本文又根据对地区区域特点的分析,提出了公路网规模预测的基本方法并对通州区的农村公路网规模进行了预测。本文研究的另一个重点是路网的布局优化。通过对公路网布局方法的分析研究,对它们在农村路网应用的效果和局限进行分析和归纳后,本文采用了一种以目标控制下网络优化法为主体,以节点重要度和区域重要度为参考的布局优化理论进行通州区的农村路网布局。编制建设时间序列和实施效果评价也是路网规划中的主要内容,本文对这两个方面进行了研究和新方法的尝试,建立了新的建设项目迫切度模型和效果评价体系,并把研究成果应用在通州区的农村公路网规划中。本文是对建立合理、完善的农村公路网规划体系的一种尝试,希望对实际应用具有一定的参考价值。关键词:农村公路;公路网规划;规模预测;布局优化;建设序列; Abstract Abstract Rural highway isakey part ofthe regional highway one ofthe most important transportation infrastructure,rural highway iscriticaltothe development ofeconomy and society recent years,China saw a rapid growth of national economy,whereas,the construction ofthe rural highway was significantly situation has been abottleneck tothe development ofthe thiscircumstances,a thorough study in themethodology ofruralhighway panning has itspracticalmeaning. This thesis takes Tongzhou DistrictofBeijing as an example,and describes the principles ofrural highway planning and the framework ofthe planning method,Follow bypointing out some main ideas ofhighway length prediction and forecasting the work scale ofTongzhou District,which are based on existing condition analysis and categorisation ofregional features. The most important content ofrural work planning islay—out optimization ofthe on research on several different highway plans;this thesis isgoing to introduce a new lay—out model bine the method work optimization controlled by target and importance ofnodes and areas. work Construction order and evaluation also are main aspects of thesis implements new research method and temptations inthese on the solid example ofTongzhou DistrictofBeijing;a new model ofimpendence and a new system work evaluation will beapplied toTongzh
