【摘要】：近年來,復雜網絡作為描述復雜系統(tǒng)模型的有效方法,已在若干領域得以應用,已有的研究表明在交通系統(tǒng)中,城市道路網絡、公交網、軌道網、鐵路網、航空網等等均具有復雜網絡性質。因此,借助復雜網絡理論研究綜合公共交通系統(tǒng)建模問題是當前的研究熱點。已有的研究主要集中于對城市公交網絡的實證,并通過計算網絡的性質來評價城市公交系統(tǒng)的合理性,作為居民出行(到達)的地理要素未被納入網絡模型中。事實上,一個結構合理的公共交通網絡應更好的服務于居民小區(qū)、城市公共設施等地理要素,忽略這些地理要素對城市公交網絡的評價是不全面的。因此,本文將地理要素融入網絡模型中,用以評價和優(yōu)化公共交通網絡。具體而言,本文主要工作如下:(1)為實現地理要素和公共交通網絡綜合建模,本文基于多子網復合復雜網絡的基本理論,提出了一種能夠描述公共交通網絡與地理要素的復合公共交通網絡模型。(2)針對城市公交網絡的評價問題,結合地理要素與公共交通站點分布關系,基于站點服務區(qū)域面積提出了居民乘車便捷性和居民換乘便捷性的評價指標。(3)以居民小區(qū)作為地理要素的代表,構建了青島市居民小區(qū)和公共交通復合網絡,分析了該網絡的基本拓撲性質,計算了青島市小區(qū)居民乘車便捷性和小區(qū)居民換乘便捷性指標,并以行政區(qū)為分析對象,統(tǒng)計了市內四區(qū)的小區(qū)居民乘車便捷性和小區(qū)居民換乘便捷性指標,發(fā)現了市北區(qū)較之其它三區(qū)出行更為便捷。(4)為減少居民小區(qū)到社區(qū)醫(yī)院就醫(yī)公交站點,以居民小區(qū)與社區(qū)醫(yī)院為地理要素,建立了居民小區(qū)、社區(qū)醫(yī)院與公共站點復合網絡,分析了青島市居民小區(qū)與社區(qū)醫(yī)院間的便捷關系,發(fā)現了青島市區(qū)內到社區(qū)醫(yī)院不便的小區(qū),并給出了公交線路優(yōu)化方法。(5)為了分析考慮地理要素的城市公共交通網絡的可靠性問題,本文以居民小區(qū)為地理要信息素代表,研究了公交線路小區(qū)復合網絡模型的可靠性。提出了對公交線路小區(qū)復合網絡模型的攻擊方式和復合網絡的可靠性的評價指標。以青島市居民小區(qū)和公交復合網絡為分析對象,對比分析了公交網絡可靠性與小區(qū)公交復合網絡可靠性,并發(fā)現小區(qū)公交復合網絡的可靠性優(yōu)于公共交通網絡。
[Abstract]:In recent years, complex network, as an effective way to describe complex system models, has been applied in several fields. The existing research shows that in the transportation system, the urban road network, the public transportation network, the track network, the railway network, the aviation network and so on all have the complex network nature. Therefore, it is a hot topic to study the modeling of integrated public transport system with the help of complex network theory. The existing researches mainly focus on the demonstration of the urban public transport network, and evaluate the rationality of the urban public transport system by calculating the nature of the network, which is not included in the network model as residents' travel (arrival) geographical elements. In fact, a reasonable public transport network should better serve the geographical elements such as residential quarters, urban public facilities and so on. Ignoring these geographical elements is not comprehensive for the evaluation of urban public transport network. Therefore, this paper integrates the geographical elements into the network model to evaluate and optimize the public transport network. Specifically, the main works of this paper are as follows: (1) in order to realize the comprehensive modeling of geographical elements and public transport network, based on the basic theory of multi subnet complex complex network, a compound public transport network model which can describe the public transportation network and geographical elements is proposed. (2) in order to evaluate the city bus network, combined with the relationship between geographical elements and public transportation site distribution, site service area based on the evaluation index of residents travel convenience and convenience for residents of the proposed. (3) in the residential area as a representative of geographical elements, the construction of Qingdao city residential area and public transportation complex networks, analyzes the basic topological properties of the network, Qingdao city residents travel convenience and convenient transfer of residential index was calculated, and the administrative region as the object of analysis and statistics of the four District of the city area residents travel convenience and district residents convenient transfer index, found the trip north than the other three areas more convenient. (4) to reduce the residential area to the community hospital bus station, to community residents and community hospitals to establish geographic factors, community residents, community hospitals and public site composite network, analyzes the relationship between Qingdao city and convenient residential community hospitals, found in the city of Qingdao to the community hospital inconvenience to the community, and gives the bus route optimization method. (5) in order to analyze the reliability of urban public transport network considering the geographical elements, this paper studies the reliability of the complex network model of public transit line communities, taking the residential area as the geographic information pheromone representative. The attack mode of the complex network model of the bus line district and the evaluation index of the reliability of the complex network are proposed. Taking Qingdao residential quarter and public transport complex network as the object of analysis, the reliability of public transport network and the reliability of community complex network are compared and analyzed, and it is found that the reliability of community complex network is better than that of public transport network.
