【摘要】：随着社会经济的发展和城市的快速扩张,城市道路网也正经历一个快速发展的过程。虽然国家和地方在城市道路网的规划和设计方面都提出了相应的规范和标准,但是这些规范和标准大都只是处于满足道路交通需求和安全的层面,未能更进一步的考虑道路交通设施人性化的方面,而对于山地城市交通设施存在的不人性化的问题就更为突出。因此,本文在对山地城市道路网的各项指标、道路网运行交通特征以及道路关键节点设计进行了深入研究的基础上,提出了一套针对山地城市道路交通设施从宏观人性化规划到微观人性化设计的山地城市交通设施人性化规划设计建议。首先,分析了山地城市交通设施规划设计现有的研究方法和设计原则等,在山地城市路网规划及评价分析中,主要分析了路网容量已有的研究方法和路网评价已有的评价方法;在山地城市道路关键节点分析中,主要分析了对于城市道路节点涉及的立交、平面交叉口、车道缩减区、指路指示等方面的研究现状、研究方法以及设计原则等。其次,从分析山地城市路网不人性化的原因入手,提出山地城市路网人性化规划的总体思路。一方面基于路网设施进行山地城市路网容量的研究,落脚点为路网密度和路网容量。另一方面基于交通运行状态进行山地城市路网人性化规划研究,提出了路网人性化服务水平、路网平衡系数等名词。并选取实例验证研究成果的科学性和合理性。最后,从山地城市道路关键节点中选取道路立交、道路平面交叉口、车道缩减区和道路指路标志四个方面进行研究。道路立交、道路平面交叉口主要参考已有的研究成果,再结合山地城市的地貌和交通特征进行改进;车道缩减区提出了当缩减车道大于一条时逐次缩减,并仿真得到平行段长度;道路指路标志方面主要在已有的规范基础上提出分级指路标志的设计和设置建议。
[Abstract]:With the development of social economy and the rapid expansion of cities, urban road network is also undergoing a rapid development process. Although national and local regulations and standards have been put forward in the planning and design of urban road networks, most of these norms and standards are only at the level of meeting the needs and safety of road traffic. The humanization of road traffic facilities is not considered further, but the problem of imhumanization of traffic facilities in mountainous cities is more prominent. Therefore, based on the in-depth study of the indexes of the road network, the traffic characteristics of the road network and the design of the key nodes of the road in mountainous cities, This paper puts forward a set of humanized planning and design suggestions for the road traffic facilities in mountainous cities from macroscopic humanized planning to microcosmic humanized design. Firstly, the existing research methods and design principles of traffic facilities planning and design in mountainous cities are analyzed. In the planning and evaluation of mountain urban road network, the existing research methods of road network capacity and the existing evaluation methods of road network evaluation are mainly analyzed. In the analysis of the key nodes of the road in mountainous cities, this paper mainly analyzes the research status, research methods and design principles of the interchanges, intersections, driveway reduction areas, directions and so on, which are involved in the urban road nodes. Secondly, starting with the analysis of the reasons why the mountain city road network is not humanized, this paper puts forward the overall thinking of the humanized planning of the mountain city road network. On the one hand, the network capacity of mountainous cities is studied based on road network facilities, and the focus is road network density and network capacity. On the other hand, the humanization planning of mountain city road network is studied based on the traffic running state, and the terms such as humanized service level of road network and road network balance coefficient are put forward. And selected an example to verify the scientific nature and rationality of the research results. Finally, four aspects of road interchange, road intersection, lane reduction area and road signage are selected from the key nodes of mountain city road. Road interchange, road intersection, the main reference to existing research results, and then combined with the landscape and traffic characteristics of mountain cities to improve the driveway reduction area proposed when the lane reduction more than one successive reduction, The length of parallel section is obtained by simulation, and the design and setting suggestions of graded road signs are put forward on the basis of existing specifications.
