【摘要】：城市道路交通網(wǎng)絡(luò)是城市發(fā)展和建設(shè)的基礎(chǔ)設(shè)施,它是由道路系統(tǒng)、社交系統(tǒng)和流量系統(tǒng)組成的典型復(fù)雜網(wǎng)絡(luò)。運(yùn)用復(fù)雜網(wǎng)絡(luò)理論的方法去研究城市道路交通網(wǎng)絡(luò)的拓?fù)涮卣?分析道路網(wǎng)絡(luò)上的交通動(dòng)力學(xué)行為,揭示城市道路交通網(wǎng)絡(luò)的發(fā)展演化規(guī)律,有利于我們從根本上去理解城市道路交通體系的運(yùn)行機(jī)制,去發(fā)現(xiàn)城市交通問(wèn)題發(fā)生的根本原因,為城市交通規(guī)劃和交通設(shè)計(jì)提供科學(xué)決策方法。 本文運(yùn)用復(fù)雜網(wǎng)絡(luò)理論,結(jié)合交通工程學(xué)、計(jì)算機(jī)仿真等相關(guān)科學(xué)和技術(shù)分析了城市道路交通網(wǎng)絡(luò)的拓?fù)涮匦?建立了相應(yīng)的網(wǎng)絡(luò)演化模型,試圖發(fā)掘和理解城市道路交通網(wǎng)絡(luò)的發(fā)展演化規(guī)律。 通過(guò)借鑒成都市城市道路交通網(wǎng)絡(luò)的演化特性,本文分別建立了“棋盤”狀城市道路交通網(wǎng)絡(luò)演化模型、“棋盤+放射線”狀城市道路交通網(wǎng)絡(luò)演化模型、“棋盤+放射線+環(huán)線”狀城市道路交通網(wǎng)絡(luò)演化模型。 通過(guò)計(jì)算機(jī)模擬發(fā)現(xiàn),在“棋盤”網(wǎng)絡(luò)演化模型中,平均路徑長(zhǎng)度隨著演化時(shí)間成線性增長(zhǎng),每單位時(shí)間步增長(zhǎng)1.3個(gè)單位長(zhǎng)度,網(wǎng)絡(luò)平均度也呈遞增趨勢(shì)。網(wǎng)絡(luò)聚類系數(shù)一直保持為O。 在“棋盤+放射線”網(wǎng)絡(luò)演化模型中,放射線的加入使得網(wǎng)絡(luò)平均度逐漸下降到一定水平,節(jié)點(diǎn)度分布并沒(méi)有明顯的分布特性。 在“棋盤+放射線+環(huán)線”網(wǎng)絡(luò)演化模型中,環(huán)線的加入使得網(wǎng)絡(luò)的聚類系數(shù)快速增長(zhǎng),同時(shí)網(wǎng)絡(luò)中會(huì)出現(xiàn)部分節(jié)點(diǎn)度較高的節(jié)點(diǎn),本文認(rèn)為環(huán)路上介數(shù)值較高的節(jié)點(diǎn)受其他鄰近節(jié)點(diǎn)連接的概率更高,在節(jié)點(diǎn)能力難以滿足交通需求時(shí),為保護(hù)這些介數(shù)值較高的節(jié)點(diǎn),在該節(jié)點(diǎn)處修建立交而造成節(jié)點(diǎn)度值較高。
[Abstract]:Urban road traffic network is the infrastructure of urban development and construction. It is a typical complex network composed of road system, social system and flow system. Using the method of complex network theory to study the topological characteristics of urban road traffic network, analyze the traffic dynamic behavior on the road network, and reveal the urban road traffic network. The law of development and evolution is helpful for us to understand the operation mechanism of urban road traffic system fundamentally, to find the fundamental cause of urban traffic problems, and to provide scientific decision-making methods for urban traffic planning and traffic design.
In this paper, the topological characteristics of urban road traffic network are analyzed by using complex network theory, combined with traffic engineering, computer simulation and other related science and technology, and a corresponding network evolution model is established to try to discover and understand the evolution and evolution of urban road traffic network.
By drawing on the evolution characteristics of urban road traffic network in Chengdu, the evolution model of "chessboard" city road traffic network, "chessboard + radioactive ray" urban road traffic network evolution model, "chessboard + radiation + ring line" urban road traffic network evolution model, are established in this paper.
Through computer simulation, it is found that in the "chessboard" network evolution model, the average path length increases linearly with the evolution time, increasing 1.3 unit length per unit time and increasing the network average degree. The network clustering coefficient has been kept as O..
In the network evolution model of "chessboard + radiation" network, the addition of radiation makes the average degree of network decrease to a certain level, and the distribution of node degree has no obvious distribution characteristics.
In the network evolution model of "chessboard + radiation + ring line" network, the connection of the loop line makes the clustering coefficient of the network increase rapidly, and there will be some nodes with high node degree in the network. This paper thinks that the nodes with higher values on the loop are more likely to be connected by other adjacent nodes, and when the node capacity is difficult to meet the traffic demand, it is difficult to meet the traffic demand. In order to protect the nodes with high intermediate values, the grade separation is built at the node, resulting in higher node value.
