【摘要】：交通是社会发展的基石,是城市发展的支撑。随着我国城市经济的快速成长,机动车的数量正在急剧增加,许多城市都出现了交通拥堵,正在影响着城市的健康发展。快速路作为城市道路网的骨架,能够满足城市居民的快速出行,快速路网的建设已成为解决城市交通问题的重要措施。长沙作为湖南省会,城市交通现状不容乐观,交通健康发展任重道远。目前,长沙城市的快速路不成系统,规模与布局满足不了交通需求,立交节点等都有待完善,尤其是部分新建道路,跨江、河桥梁的近期建设达不到远期快速路的改造标准。基于此,文章选择研究长沙城市的快速路网。论文首先提出长沙建设城市快速路的必要性。根据长沙城市的现状,通过对城市交通的分析与评价,预测规划年末的机动车交通,根据“供需平衡法”对城市快速路网规模进行合理取值。依据城市快速路规划布局的理论与方法,结合长沙城市的总体规划,通过对长沙城市的重点区域进行分析与探讨,得到长沙城市的快速路网规划方案。对城市立交节点与出入口进行功能分析,根据立交设置的原则与选型的要求,对长沙市快速路网规划方案的节点进行规划布置。评价快速路网规划方案。采用模糊评价的方法,通过对技术、经济、社会、环境等方面的指标值进行评估,得到长沙城市快速路网合理规划方案,指导城市路网建设,提高道路使用效率。
[Abstract]:Traffic is the cornerstone of social development and the support of urban development. With the rapid growth of urban economy in China, the number of motor vehicles is increasing rapidly, and many cities are experiencing traffic congestion, which is affecting the healthy development of cities. As the skeleton of urban road network, expressway can meet the rapid travel of urban residents. The construction of expressway has become an important measure to solve urban traffic problems. Changsha as a Hunan Province, the status of urban traffic is not optimistic, the healthy development of traffic is a long way to go. At present, the expressway of Changsha city is not systematic, the scale and layout can not meet the traffic demand, and the interchange nodes need to be improved, especially the recent construction of some newly built roads, across rivers and rivers can not reach the long-term expressway reconstruction standard. Based on this, the article chooses to study the expressway network of Changsha city. Firstly, the paper puts forward the necessity of constructing urban expressway in Changsha. According to the present situation of Changsha city, through the analysis and evaluation of urban traffic, the motor vehicle traffic at the end of the planning year is forecasted, and the scale of urban expressway road network is reasonably chosen according to "supply and demand balance method". According to the theory and method of urban expressway planning and layout, combined with the overall planning of Changsha city, through the analysis and discussion of the key areas of Changsha city, the plan of expressway network planning of Changsha city is obtained. The function of urban interchange nodes and entrances are analyzed. According to the principle of interchange setting and the requirements of type selection, the nodes of Changsha Expressway network planning scheme are planned and arranged. Evaluate the plan of expressway network planning. By using the method of fuzzy evaluation, through evaluating the index values of technology, economy, society, environment and so on, the rational planning scheme of Changsha urban expressway network is obtained, which can guide the construction of urban road network and improve the efficiency of road use.
