【摘要】：城市交通網(wǎng)絡(luò)是我們賴以生存的物質(zhì)條件,承載著人類活動(dòng)的基本要素,同時(shí)也是一個(gè)地區(qū)經(jīng)濟(jì)文化發(fā)展的助推力量,影響著城市的經(jīng)濟(jì)建設(shè)腳步和運(yùn)行效率。其本身就是一個(gè)復(fù)雜的巨系統(tǒng),主要包括道路子系統(tǒng),管理子系統(tǒng),流量子系統(tǒng),各個(gè)子系統(tǒng)之間相互影響,功能集聚,使得它的運(yùn)行規(guī)律也相對(duì)復(fù)雜。因此我們?cè)诔鞘薪煌ňW(wǎng)絡(luò)的研究過程中,不能割裂開來,而是要以一個(gè)整體全局的觀點(diǎn)去深入研究,更好地理解城市交通網(wǎng)絡(luò)內(nèi)在的運(yùn)行機(jī)理和規(guī)律。本文我們結(jié)合交通路網(wǎng)模型知識(shí),元胞自動(dòng)機(jī)理論以及自適應(yīng)局部路由策略來綜合考量城市交通路網(wǎng),分別從宏觀和微觀兩方面入手,針對(duì)實(shí)際交通網(wǎng)絡(luò)中車輛擁塞的疏導(dǎo)提出切實(shí)可行的路由策略,通過局部信息的控制以及優(yōu)化達(dá)到提高整個(gè)網(wǎng)絡(luò)容量的目的,為人們出行提供更加便捷的交通環(huán)境。以下為本文研究的具體內(nèi)容:(1)從宏觀的角度出發(fā),建立城市復(fù)雜動(dòng)態(tài)路網(wǎng)模型。綜合考慮了路周信息如商業(yè)圈,學(xué)校,企業(yè)所在地等影響因素和動(dòng)態(tài)時(shí)變因素對(duì)整個(gè)交通網(wǎng)絡(luò)的影響,包括人流量和車流量以及不確定的天氣情況信息。確定這局部因素對(duì)整個(gè)網(wǎng)絡(luò)擁塞所帶來的負(fù)面影響。(2)從微觀的角度出發(fā),基于駕駛員流動(dòng)性偏好的元胞自動(dòng)機(jī)理論,建立交通流模型。主要考慮駕駛員的個(gè)性特點(diǎn)而產(chǎn)生的駕駛員之間的異步行為對(duì)整個(gè)交通網(wǎng)絡(luò)的影響。(3)交通疏導(dǎo)策略研究。結(jié)合模擬的交通數(shù)據(jù)如:車輛個(gè)數(shù),路段暢通情況,預(yù)測(cè)信息等海量信息數(shù)據(jù),運(yùn)用自適應(yīng)局部動(dòng)態(tài)誘導(dǎo)的方法,結(jié)合網(wǎng)絡(luò)中動(dòng)態(tài)信息的變化,如拓?fù)浣Y(jié)構(gòu)的變化或是車輛等待排隊(duì)時(shí)間等因素,局部搜索適應(yīng)度高的鄰居節(jié)點(diǎn),通過引入可調(diào)節(jié)參數(shù)?的不同取值,來給定車輛傳輸?shù)膶?shí)際路徑,直至車輛到達(dá)目標(biāo)節(jié)點(diǎn)并從網(wǎng)絡(luò)中消失。
[Abstract]:Urban traffic network is the material condition on which we depend, carries the basic elements of human activities, and is also the booster of the economic and cultural development of a region, which affects the pace and efficiency of urban economic construction. It is a complex giant system, which mainly includes road subsystem, management subsystem, flow subsystem, each subsystem affects each other, and the function aggregates, which makes its operation law relatively complex. Therefore, in the research process of urban traffic network, we should not be separated, but should study deeply from the point of view of the whole situation, and better understand the internal operation mechanism and law of urban traffic network. In this paper, based on the knowledge of traffic network model, cellular automaton theory and adaptive local routing strategy, we consider the urban traffic network synthetically. From the macro and micro aspects, we propose a feasible routing strategy for the dredging of vehicle congestion in the actual traffic network. Through the control and optimization of local information, we can achieve the purpose of improving the capacity of the whole network, so as to provide a more convenient traffic environment for people to travel. The following are the specific contents of this paper: (1) from the macro point of view, the urban complex dynamic road network model is established. The influence of road and traffic information such as business circle, school, enterprise location and dynamic time-varying factors on the whole traffic network is considered, including passenger flow and traffic flow, as well as uncertain weather information. The negative influence of this local factor on the whole network congestion is determined. (2) from the microscopic point of view, based on the cellular automaton theory of driver liquidity preference, the traffic flow model is established. This paper mainly considers the influence of asynchronous behavior between drivers on the whole traffic network caused by the personality characteristics of drivers. (3) Research on traffic grooming strategy. Combined with the simulated traffic data such as the number of vehicles, the smooth flow of road sections, prediction information and other massive information data, using the method of adaptive local dynamic induction, combined with the changes of dynamic information in the network, such as the change of topological structure or waiting time of vehicles, the local search for neighbor nodes with high adaptability is carried out, and the adjustable parameters are introduced. The actual path of the vehicle transmission is given until the vehicle reaches the target node and disappears from the network.
