【摘要】：在城市新区飞速发展的大背景下，新区交通规划工作将是其规划工作中的重点和难点。同时，传统的交通规划工作思路中缺乏对土地利用和交通系统之间的互动反馈的思考，交通系统往往处于从属地位，这样的理念是导致当前交通问题频出的根本原因之一，亟需改进。而新区交通发展也有着不同于旧城区的一些特性，传统交通规划方法对新城交通规划的适应性有待研究。 本文首先对城市新区的土地利用特性和交通需求特性进行了相应的分析，提出了城市新区的交通特性可以通过规划进行调整和引导。研究了中观层面的土地利用规划与交通系统相协调的研究的必要性，并指出中观层面关键性的土地利用指标——容积率和交通系统指标——路网承载力。在研究现有交通规划方法在城市新区的应用不足之后，针对城市新区的特点，提出了适合城市新区的交通规划理念，并给出了思路和方法的流程。 然后，针对路网承载力，分析了城市新区路网承载力的特性和影响因素，提出了基于控制指标的路网极限承载力的概念，并基于此构建了城市新区路网极限承载力模型。利用遗传算法和局部优化算法，，对模型的求解提出了组合算法。 提出城市新区路网极限承载力模型后，基于前文的新区交通规划思路，提出城市新区交通需求控制指标规划，利用路网极限承载力反算路网能承受的极限小区发生吸引量，以此来实现对各分区地块进行土地利用规划控制性反馈。文中指出其规划的核心思想、整体规划的技术路线以及进行需求控制规划的步骤和重点。 最后，针对土地利用控规调整后交通需求的变化，提出了新区道路网技术指标优化模型，为城市新区道路网优化改造提供量化支撑。
[Abstract]:Under the background of the rapid development of the new urban area, the traffic planning of the new area will be the focus and difficulty in the planning work. At the same time, there is a lack of interactive feedback between land use and transportation system in the traditional traffic planning. The idea that traffic systems are often in a subordinate position is one of the root causes of the current traffic problems and needs to be improved. The traffic development of the new district also has some characteristics that are different from those in the old urban areas. The adaptability of the traditional traffic planning method to the new town traffic planning needs to be studied. In this paper, the characteristics of land use and traffic demand in new urban areas are analyzed. It is pointed out that the traffic characteristics of the new urban area can be adjusted and guided by planning, and the necessity of coordinating the land use planning and traffic system at the middle level is studied. It also points out that the key indexes of land use and traffic system are the capacity of road network. After studying the application of existing traffic planning methods in new urban areas, the characteristics of new urban areas are pointed out. The traffic planning idea suitable for the new urban area is put forward, and the flow chart of the train of thought and method is given. Then, in view of the road network bearing capacity, the paper analyzes the characteristics and influencing factors of the road network bearing capacity in the new urban area, and puts forward the concept of the road network ultimate bearing capacity based on the control index. Based on this, the ultimate bearing capacity model of urban new area road network is constructed, and a combined algorithm is proposed to solve the model by using genetic algorithm and local optimization algorithm. After putting forward the model of the ultimate bearing capacity of the road network of the new urban area, based on the thought of the traffic planning of the new area mentioned above, the paper puts forward the planning of the traffic demand control index of the new area of the city, and uses the ultimate bearing capacity of the road network to calculate the amount of attraction that the road network can bear. The paper points out the core idea of the land use planning, the technical route of the whole planning and the steps and emphases of the demand control planning. Finally, according to the change of traffic demand after land use regulation adjustment, the optimization model of new area road network technology index is put forward, which can provide quantitative support for urban new area road network optimization and reconstruction.
