【摘要】：隨著城市化、機動化進程的加快,交通需求與空間局限的沖突愈演愈烈,國內城市擁堵問題日益嚴重。自2005年北京政府工作報告中提出“微循環(huán)”以來,作為道路資源的“新大陸”,如何有效利用其內部網絡分擔干道交通壓力、緩解城市擁堵,成為近年來微循環(huán)系統(tǒng)功能優(yōu)化的研究核心。但除了緩解城市擁堵、提高交通效率,微循環(huán)系統(tǒng)本身也是區(qū)域內居民基本的活動場所,承載著居民的出行需求與生活需求,是城市生態(tài)的重要組成。所以,對微循環(huán)系統(tǒng)的功能優(yōu)化應當是系統(tǒng)的多目標過程,而這正是傳統(tǒng)研究所缺乏的。探討多目標下城市交通微循環(huán)系統(tǒng)功能優(yōu)化的原理與方法,具有重要的理論與實踐意義。 本文首先以國內外學者的研究為基礎,結合自身理解,對城市交通微循環(huán)系統(tǒng)進行了定義,指出城市交通微循環(huán)系統(tǒng)是包含交通網絡和人的經濟、文化等活動的有機整體；接下來詳細梳理了微循環(huán)系統(tǒng)的組成及特性,并指出現(xiàn)狀研究所存在的問題,確定研究的必要性與意義所在。 其次,從不同層面入手,分析了微循環(huán)系統(tǒng)功能與優(yōu)化需求,論證了微循環(huán)系統(tǒng)多目標優(yōu)化過程的必須性；并根據(jù)微循環(huán)系統(tǒng)功能與特性設計了基于多目標效用理論、決策行為理論及多目標決策理論的系統(tǒng)功能優(yōu)化方法,提出描述優(yōu)化方案接受程度的決策阻抗函數(shù),改變了傳統(tǒng)微循環(huán)系統(tǒng)功能優(yōu)化目標間難以比較,無法合理有效地進行多目標分析優(yōu)化的狀況。 最后,基于多目標優(yōu)化方法,在構建雙層規(guī)劃模型求解網絡優(yōu)化方案的基礎上,提出涵蓋交通組織、靜態(tài)交通管理、慢行系統(tǒng)設置及生活環(huán)境優(yōu)化等在內的微循環(huán)系統(tǒng)組合優(yōu)化策略,并設計算例加以檢驗。算例結果證明了研究方法的有效性與可行性,對微循環(huán)系統(tǒng)功能優(yōu)化研究有一定的積極意義。
[Abstract]:With the acceleration of urbanization and motorization, the conflict between traffic demand and space limitation is becoming more and more serious, and the problem of urban congestion is becoming more and more serious. Since the "microcirculation" was put forward in the 2005 Beijing government work report, how to effectively use its internal network to share the traffic pressure of the main road and alleviate the urban congestion, as the "new continent" as a road resource, In recent years, it has become the core of the research on the function optimization of microcirculation system. However, in addition to alleviating urban congestion and improving traffic efficiency, microcirculation system itself is also the basic activity place of residents in the region, carrying the travel and living needs of residents, which is an important component of urban ecology. Therefore, the function optimization of microcirculation system should be a multi-objective process of the system, which is lack of traditional research. It is of great theoretical and practical significance to discuss the principle and method of optimizing the function of urban traffic microcirculation system under multi-objective. Based on the research of scholars at home and abroad, this paper defines the urban traffic microcirculation system, and points out that the urban traffic microcirculation system is an organic whole including traffic network, human economy, culture and so on. Then the composition and characteristics of the microcirculation system are analyzed in detail, and the problems in the present research are pointed out, and the necessity and significance of the research are determined. Secondly, from different aspects, the function and optimization requirements of microcirculation system are analyzed, the necessity of multi-objective optimization process of microcirculation system is demonstrated, and the multi-objective utility theory is designed according to the function and characteristics of microcirculation system. The system function optimization method based on decision behavior theory and multi-objective decision theory is presented. A decision impedance function describing the acceptance degree of optimization scheme is proposed, which changes the difficulty of comparing the traditional microcirculation system function optimization objectives. The condition of multi-objective analysis and optimization can not be carried out reasonably and effectively. Finally, based on the multi-objective optimization method and the bilevel programming model to solve the network optimization scheme, the traffic organization and static traffic management are proposed. The combination optimization strategy of microcirculation system including slow moving system setting and living environment optimization is designed and tested. The results show that the method is effective and feasible, and it is of great significance to the study of microcirculation system function optimization.
