【摘要】：考慮到城市公交網(wǎng)絡(luò)的生成和演化受到城市道路交通網(wǎng)絡(luò)結(jié)構(gòu)約束的現(xiàn)實(shí),利用復(fù)雜網(wǎng)絡(luò)的最新研究分支-空間網(wǎng)絡(luò)相關(guān)理論,構(gòu)建了適于城市道路交通網(wǎng)絡(luò)的DMG約束空間;生成了DMG空間約束下的公交站點(diǎn)分布規(guī)則,并基于嵌套最短路徑,提出了一個(gè)城市公交網(wǎng)絡(luò)的演化模型。以遼陽市道路和公交網(wǎng)絡(luò)為實(shí)證對象,將模型的結(jié)果與實(shí)際統(tǒng)計(jì)數(shù)據(jù)結(jié)果進(jìn)行了對比,發(fā)現(xiàn)模型的仿真結(jié)果與實(shí)際數(shù)據(jù)可以很好地吻合,表明了此模型的有效性;利用此模型對城市建設(shè)速率和城市公交建設(shè)速率的相互關(guān)系進(jìn)行了分析,結(jié)果表明,當(dāng)兩者比值呈現(xiàn)2個(gè)極端時(shí),公交線網(wǎng)密度都會呈現(xiàn)幾何級數(shù)級的變化。這為進(jìn)行城市建設(shè)和交通建設(shè)規(guī)劃的速度問題提供了一個(gè)決策依據(jù)。同時(shí),本模型也揭示了城市公交網(wǎng)絡(luò)演化的一般規(guī)律,為城市公交網(wǎng)絡(luò)演化的研究提供了一種新思路。
[Abstract]:Considering the fact that the generation and evolution of urban public transport network is constrained by the urban road traffic network structure, the DMG constraint space suitable for urban road traffic network is constructed by using the relevant theory of space network, which is the newest research branch of complex network. The distribution rules of bus stations under DMG space constraints are generated. Based on the nested shortest path, an evolutionary model of urban public transport network is proposed. Taking the road and bus network of Liaoyang city as an example, the results of the model and the actual statistical data are compared, and it is found that the simulation results of the model are in good agreement with the actual data, which shows the validity of the model. The model is used to analyze the relationship between the urban construction rate and the urban transit construction rate. The results show that when the ratio of the two is two extremes, the density of the bus network will show a geometric series change. This provides a decision basis for the speed of urban construction and traffic construction planning. At the same time, this model also reveals the general law of urban transit network evolution, and provides a new way for the study of urban transit network evolution.
