【摘要】：隨著城市化進(jìn)程的加快,城市規(guī)模不斷擴(kuò)大,城市人口直線增加,交通擁堵、尾氣排放等交通問(wèn)題已經(jīng)變得十分嚴(yán)重。以往的交通發(fā)展思路在如此嚴(yán)峻的交通問(wèn)題下是不符合現(xiàn)實(shí)要求的,難以解決城市居民的出行問(wèn)題。與此同時(shí)國(guó)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(lái)越被人們所認(rèn)可。因此,公共交通可達(dá)性的研究變得越來(lái)越重要,這對(duì)解決城市交通問(wèn)題,方便居民出行等方面具有重大意義。論文通過(guò)分析國(guó)內(nèi)外可達(dá)性研究現(xiàn)狀,分析城市公交系統(tǒng)可達(dá)性影響因素,在已有的可達(dá)性評(píng)價(jià)模型的基礎(chǔ)上,提出了城市公交可達(dá)性理論。論文中提出了關(guān)于城市公交可達(dá)性評(píng)價(jià)指標(biāo)的數(shù)學(xué)模型,此模型是通過(guò)結(jié)合空間阻隔模型、累計(jì)機(jī)會(huì)模型、時(shí)空約束模型和拓?fù)涠攘糠ǖ瓤蛇_(dá)性研究方法,進(jìn)而從宏觀、中觀和微觀層面加以研究可達(dá)性而得到。此模型對(duì)城市公交系統(tǒng)的可達(dá)性評(píng)價(jià)具有全面和多層次的特點(diǎn),可以給出公交系統(tǒng)的可達(dá)性水平,并找出系統(tǒng)缺陷。論文基于TransCAD軟件對(duì)蘭州市公交系統(tǒng)可達(dá)性進(jìn)行了分析,設(shè)計(jì)了公交路線系統(tǒng),創(chuàng)建城市公交網(wǎng)絡(luò)數(shù)據(jù)庫(kù),此數(shù)據(jù)庫(kù)的核心內(nèi)容由空間地理數(shù)據(jù)庫(kù)和公交路線系統(tǒng)數(shù)據(jù)庫(kù)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(biāo)準(zhǔn)并設(shè)計(jì)關(guān)于最優(yōu)路徑的計(jì)算方法。論文最后從蘭州市當(dāng)前面臨的交通問(wèn)題出發(fā),從線路長(zhǎng)度、非直線系數(shù)、平均站距和站點(diǎn)線路集中度四方面對(duì)蘭州市公交空間特征進(jìn)行了分析,在此基礎(chǔ)上,從空間可達(dá)性、時(shí)間可達(dá)性和費(fèi)用可達(dá)性方面,對(duì)宏觀、中觀、微觀層面進(jìn)行了模型分析,最后根據(jù)分析結(jié)果,提出了緩解交通問(wèn)題的相關(guān)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.
