【摘要】：隨著城市機(jī)動(dòng)車輛的大幅度增長,城市交通問題變得日益嚴(yán)峻;城市交通系統(tǒng)龐大而復(fù)雜,經(jīng)過研究發(fā)現(xiàn)城市道路交通網(wǎng)絡(luò)具有明顯的復(fù)雜網(wǎng)絡(luò)特征,因此,為了緩解交通的擁堵問題,一些學(xué)者們開始研究如何將復(fù)雜網(wǎng)絡(luò)的知識運(yùn)用到城市道路交通領(lǐng)域。本文在復(fù)雜網(wǎng)絡(luò)理論的基礎(chǔ)上,建立了城市道路交通網(wǎng)絡(luò)模型,提出了基于SIS的動(dòng)態(tài)失效模型,設(shè)計(jì)了考慮動(dòng)態(tài)失效的路網(wǎng)節(jié)點(diǎn)重要性評價(jià)方法,并以北京市城市道路交通網(wǎng)絡(luò)為例,分析了路網(wǎng)的統(tǒng)計(jì)特征以及其在靜態(tài)失效條件下重要統(tǒng)計(jì)特征的變化,通過對路網(wǎng)的動(dòng)態(tài)失效模型的實(shí)驗(yàn)仿真,深入分析了交通網(wǎng)絡(luò)擁堵動(dòng)態(tài)演進(jìn)過程,并分析了考慮動(dòng)態(tài)失效的路網(wǎng)節(jié)點(diǎn)重要性。本文首先構(gòu)建了城市道路交通網(wǎng)絡(luò)的三種網(wǎng)絡(luò)模型,探討了路網(wǎng)節(jié)點(diǎn)重要性靜態(tài)評估方法,繼而結(jié)合交通網(wǎng)絡(luò)的特點(diǎn)和傳染病模型原理,建立了基于SI的動(dòng)態(tài)失效模型和基于SIS的動(dòng)態(tài)失效模型,通過對它們進(jìn)行對比分析得知,在較長時(shí)間跨度內(nèi),基于SIS的動(dòng)態(tài)失效模型比基于SI的動(dòng)態(tài)失效模型更為合理。其次,在基于SIS的動(dòng)態(tài)失效模型基礎(chǔ)上,結(jié)合路網(wǎng)節(jié)點(diǎn)重要性靜態(tài)評估方法,提出了一種考慮動(dòng)態(tài)失效的路網(wǎng)節(jié)點(diǎn)重要性評價(jià)方法,即路網(wǎng)節(jié)點(diǎn)重要性動(dòng)態(tài)評估方法,通過靜態(tài)評估方法和動(dòng)態(tài)評估方法的對比分析,證明了路網(wǎng)節(jié)點(diǎn)重要性動(dòng)態(tài)評估方法的合理性。再次,構(gòu)建了北京市城市道路交通網(wǎng)絡(luò)的三種網(wǎng)絡(luò)模型,通過實(shí)驗(yàn)分析得知抽象網(wǎng)絡(luò)有其隨機(jī)網(wǎng)絡(luò)的特點(diǎn),基礎(chǔ)設(shè)施網(wǎng)絡(luò)和動(dòng)態(tài)交通流網(wǎng)絡(luò)均有無標(biāo)度網(wǎng)絡(luò)的特點(diǎn),通過實(shí)驗(yàn)分析了三種網(wǎng)絡(luò)在不同失效模式下的重要統(tǒng)計(jì)特征,表明基礎(chǔ)設(shè)施網(wǎng)絡(luò)和以旅行時(shí)間為權(quán)值的動(dòng)態(tài)交通流網(wǎng)絡(luò)在隨機(jī)性失效條件下具有很強(qiáng)的魯棒性,在蓄意失效條件下具有很強(qiáng)的脆弱性。最后,通過實(shí)驗(yàn)分析了動(dòng)態(tài)失效條件下路網(wǎng)阻塞系數(shù),得知蓄意失效條件下,網(wǎng)絡(luò)擁堵速度較隨機(jī)失效條件下快,并且最終的擁堵規(guī)模更大;通過對不同影響能力系數(shù)條件下路網(wǎng)阻塞系數(shù)進(jìn)行實(shí)驗(yàn)分析,得知節(jié)點(diǎn)間的耦合強(qiáng)度對擁堵傳播有重要影響,最后,通過實(shí)驗(yàn)仿真對考慮動(dòng)態(tài)失效的北京市城市道路交通網(wǎng)絡(luò)的節(jié)點(diǎn)重要性進(jìn)行了評價(jià)。
[Abstract]:With the rapid growth of urban motor vehicles, urban traffic problems become more and more serious, and the urban traffic system is huge and complex. Through the research, it is found that urban road traffic network has obvious complex network characteristics, so, In order to alleviate the problem of traffic congestion, some scholars begin to study how to apply the knowledge of complex network to the field of urban road traffic. In this paper, based on the theory of complex network, a model of urban road traffic network is established. This paper presents a dynamic failure model based on SIS, designs a method to evaluate the importance of road network nodes considering dynamic failure, and takes the urban road traffic network in Beijing as an example. This paper analyzes the statistical characteristics of the road network and the changes of its important statistical characteristics under the static failure condition. Through the experimental simulation of the dynamic failure model of the road network, the dynamic evolution process of the traffic network congestion is deeply analyzed. The importance of road network node considering dynamic failure is analyzed. Firstly, three kinds of network models of urban road traffic network are constructed, and the static evaluation method of road network node importance is discussed. Then, combining the characteristics of traffic network and the principle of infectious disease model, the dynamic failure model based on SI and the dynamic failure model based on SIS are established. The dynamic failure model based on SIS is more reasonable than the dynamic failure model based on SI. Secondly, based on the dynamic failure model based on SIS, combined with the static evaluation method of road network node importance, In this paper, a method for evaluating the importance of road network nodes considering dynamic failure is proposed, that is, the dynamic evaluation method of road network node importance, which is compared with the static evaluation method and the dynamic evaluation method. This paper proves the rationality of the dynamic evaluation method of road network node importance. Thirdly, three kinds of network models of Beijing urban road traffic network are constructed, and the abstract network has the characteristics of random network through experimental analysis. Both infrastructure network and dynamic traffic flow network have the characteristics of scale or not. The important statistical characteristics of three kinds of networks under different failure modes are analyzed through experiments. It is shown that the infrastructure network and the dynamic traffic flow network weighted by travel time have strong robustness under random failure conditions and strong vulnerability under deliberate failure conditions. Through the experimental analysis of road network congestion coefficient under dynamic failure condition, it is known that the network congestion speed is faster than that under random failure condition, and the final congestion scale is larger. Through the experimental analysis of road network congestion coefficient under different influence capacity coefficient, it is known that the coupling strength between nodes has an important effect on congestion propagation. The node importance of Beijing urban road traffic network considering dynamic failure is evaluated by experimental simulation.
