【摘要】：隨著我國城市化和機(jī)動化進(jìn)程的加快,各大城市的車流量急劇增加,原有的道路設(shè)施已經(jīng)不堪重負(fù),交通擁堵狀況越來越嚴(yán)重,已成為各大城市亟須解決的重要問題之一。為了解決城市交通擁堵,大力發(fā)展公共交通,實(shí)行“公交優(yōu)先”的戰(zhàn)略,進(jìn)而促進(jìn)城市經(jīng)濟(jì)發(fā)展、提高道路資源利用率。但是由于缺少實(shí)時(shí)動態(tài)的網(wǎng)絡(luò)化公交調(diào)度方法,使得智能公交調(diào)度平臺并不能充分發(fā)揮其作用,很難有效的提高車輛準(zhǔn)點(diǎn)率、車內(nèi)舒適度以及乘客等車時(shí)間等公交服務(wù)水平。因此,對公交調(diào)度的網(wǎng)絡(luò)化和動態(tài)化研究顯得十分必要。 論文依托國家自然科學(xué)基金項(xiàng)目“面向車輛調(diào)度的公交動態(tài)網(wǎng)絡(luò)復(fù)雜性及其實(shí)證研究(No.51308176)”內(nèi)容來展開研究,對城市公交運(yùn)營網(wǎng)絡(luò)的相關(guān)特性以及網(wǎng)絡(luò)化和動態(tài)化的調(diào)度策略展開研究。首先,以公交車輛在網(wǎng)絡(luò)上的運(yùn)行軌跡為原型,構(gòu)建以公交�？空军c(diǎn)作為網(wǎng)絡(luò)的節(jié)點(diǎn),車輛在網(wǎng)絡(luò)上的實(shí)時(shí)位置作為網(wǎng)絡(luò)邊的城市公交動態(tài)網(wǎng)絡(luò)。車輛在城市道路網(wǎng)上位置的實(shí)時(shí)變動使得構(gòu)建的公交網(wǎng)絡(luò)具備了時(shí)變的特性。其次,利用不同的建模機(jī)制對城市公交動態(tài)網(wǎng)絡(luò)模型進(jìn)行抽象,對得到的公交網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)以及相關(guān)動力學(xué)特性進(jìn)行研究分析,為網(wǎng)絡(luò)化車輛調(diào)度提供一種新的思路。然后,分析一路一線和多路多線公交動態(tài)模型的車流特性,對網(wǎng)絡(luò)的統(tǒng)計(jì)學(xué)特性進(jìn)行研究,通過實(shí)例仿真分析,提取網(wǎng)絡(luò)相關(guān)的特征參數(shù)作為識別公交分布狀態(tài)的重要指標(biāo)。最后,對異常狀態(tài)下公交的實(shí)時(shí)運(yùn)營狀態(tài)進(jìn)行分析,并且通過制定相應(yīng)的公交動態(tài)控制策略使得網(wǎng)絡(luò)趨于穩(wěn)定。通過上述分析,將復(fù)雜動態(tài)網(wǎng)絡(luò)理論的分析方法引入到公交調(diào)度領(lǐng)域,提出了一種新的解決公交調(diào)度問題的途經(jīng),體現(xiàn)出可行性和先進(jìn)性。
[Abstract]:With the acceleration of urbanization and motorization in China, the traffic flow of major cities has increased sharply, the original road facilities have been overwhelmed and traffic congestion has become more and more serious, which has become one of the important problems that need to be solved urgently. In order to solve urban traffic congestion, develop public transportation vigorously, implement the strategy of "public transportation priority", and then promote the development of urban economy and improve the utilization rate of road resources. However, due to the lack of real-time and dynamic network bus scheduling methods, intelligent bus scheduling platform can not fully play its role, and it is difficult to effectively improve the bus service level, such as vehicle punctuality, in-vehicle comfort and passenger waiting time. Therefore, it is necessary to study the network and dynamic of bus dispatch. Based on the National Natural Science Foundation of China (NSFC) project, "the complexity of bus dynamic Network for vehicle Dispatch and its empirical Research No. No. 51308176)", the thesis carries out the research. The related characteristics of urban transit network and the network and dynamic scheduling strategies are studied. First of all, based on the track of public transport vehicles in the network as a prototype, the bus stop as the node of the network, the real-time location of the vehicle in the network as the network of urban public transport dynamic network. The real-time change of vehicle location on the urban road network makes the constructed bus network have the characteristics of time-varying. Secondly, the dynamic network model of urban public transport is abstracted by different modeling mechanisms, and the topological structure and related dynamic characteristics of the network are studied and analyzed, which provides a new way of thinking for networked vehicle scheduling. Then, the characteristics of traffic flow in the dynamic model of one route and multi-route bus are analyzed, and the statistical characteristics of the network are studied. Through the simulation analysis, the characteristic parameters related to the network are extracted as important indicators to identify the distribution state of public transportation. Finally, the real-time operation state of public transportation in abnormal state is analyzed, and the network tends to be stable by making the corresponding dynamic control strategy of public transportation. Through the above analysis, the analysis method of complex dynamic network theory is introduced into the field of public transportation dispatch, and a new way to solve the problem of public transportation dispatch is put forward, which embodies the feasibility and advanced nature.
