【摘要】：隨著城市化進程的加快,城市規(guī)模不斷擴大,城市人口直線增加,交通擁堵、尾氣排放等交通問題已經(jīng)變得十分嚴重。以往的交通發(fā)展思路在如此嚴峻的交通問題下是不符合現(xiàn)實要求的,難以解決城市居民的出行問題。與此同時國家大力發(fā)展公共交通,低碳生活和綠色出行的理念也越來越被人們所認可。因此,公共交通可達性的研究變得越來越重要,這對解決城市交通問題,方便居民出行等方面具有重大意義。論文通過分析國內外可達性研究現(xiàn)狀,分析城市公交系統(tǒng)可達性影響因素,在已有的可達性評價模型的基礎上,提出了城市公交可達性理論。論文中提出了關于城市公交可達性評價指標的數(shù)學模型,此模型是通過結合空間阻隔模型、累計機會模型、時空約束模型和拓撲度量法等可達性研究方法,進而從宏觀、中觀和微觀層面加以研究可達性而得到。此模型對城市公交系統(tǒng)的可達性評價具有全面和多層次的特點,可以給出公交系統(tǒng)的可達性水平,并找出系統(tǒng)缺陷。論文基于TransCAD軟件對蘭州市公交系統(tǒng)可達性進行了分析,設計了公交路線系統(tǒng),創(chuàng)建城市公交網(wǎng)絡數(shù)據(jù)庫,此數(shù)據(jù)庫的核心內容由空間地理數(shù)據(jù)庫和公交路線系統(tǒng)數(shù)據(jù)庫兩部分組成。在考慮“出行距離最短”和“換乘次數(shù)”等因素后,建立公交出行路徑廣義成本模型,最后確定公交的最佳路徑判斷標準并設計關于最優(yōu)路徑的計算方法。論文最后從蘭州市當前面臨的交通問題出發(fā),從線路長度、非直線系數(shù)、平均站距和站點線路集中度四方面對蘭州市公交空間特征進行了分析,在此基礎上,從空間可達性、時間可達性和費用可達性方面,對宏觀、中觀、微觀層面進行了模型分析,最后根據(jù)分析結果,提出了緩解交通問題的相關措施。
[Abstract]:With the acceleration of the urbanization process, the scale of the city continues to expand, urban population increases in a straight line, traffic congestion. Exhaust emissions and other traffic problems have become very serious. In the past, the train of thought of traffic development in such a severe traffic problem is not in line with the practical requirements. It is difficult to solve the travel problem of urban residents. At the same time, the concept of low carbon living and green travel is more and more accepted by people. The research of public transportation accessibility has become more and more important, which is of great significance to solve urban traffic problems and facilitate residents travel. This paper analyzes the current situation of accessibility research at home and abroad. Based on the analysis of the factors affecting the reachability of urban public transport system, this paper puts forward the theory of the reachability of urban public transport on the basis of the existing reachability evaluation model, and puts forward the mathematical model of the evaluation index of the accessibility of urban public transport. This model is based on the spatial barrier model, cumulative opportunity model, space-time constraint model and topology measurement methods, and then from the macro. The model has the characteristics of comprehensive and multi-level, and can give the reachability level of the public transport system. Based on the TransCAD software, the reachability of the public transport system in Lanzhou is analyzed, the bus route system is designed, and the database of urban public transport network is established. The core content of this database is composed of two parts: spatial geographical database and bus route system database. After considering the factors such as "shortest travel distance" and "transfer frequency" and so on. The paper establishes a generalized cost model of public transport route, finally determines the criteria of the best path of public transport and designs the calculation method of the optimal path. Finally, the paper starts from the current traffic problems in Lanzhou. This paper analyzes the spatial characteristics of public transportation in Lanzhou from four aspects: line length, non-linear coefficient, average station distance and line concentration degree. On this basis, the spatial reachability, time reachability and cost reachability are analyzed. The model analysis of macro, meso and micro level is carried out. Finally, according to the analysis results, the related measures to alleviate traffic problems are put forward.
