【摘要】：智能運(yùn)輸系統(tǒng)(ITS)是未來(lái)交通的發(fā)展方向,仿真技術(shù)是研究交通系統(tǒng)的有效手段,城市交通仿真模型的成功搭建可為交通方案與決策提供測(cè)試與評(píng)價(jià)平臺(tái),對(duì)城市交通規(guī)劃具有強(qiáng)有力的支撐作用。城市道路交通流是一種復(fù)雜的網(wǎng)絡(luò)交通流,且城市用地資源相對(duì)有限,傳統(tǒng)的宏觀(guān)需求預(yù)測(cè)模型已無(wú)法滿(mǎn)足交通規(guī)劃與管理的精細(xì)化要求,因此有必要建立滿(mǎn)足精細(xì)化設(shè)計(jì)要求的交通模型。本文首先對(duì)比了宏觀(guān)、微觀(guān)以及中觀(guān)交通仿真技術(shù)的優(yōu)缺點(diǎn),在此基礎(chǔ)上闡述了中觀(guān)交通模型的優(yōu)勢(shì),引出搭建城市道路交通中觀(guān)仿真模型的重要性。本文提出基于宏觀(guān)繼承法的中觀(guān)交通模型建立方法與步驟,從Cube Voyager平臺(tái)下的西安城市交通模型中提取出中觀(guān)子區(qū)模型,結(jié)合西安高新區(qū)的交通實(shí)測(cè)數(shù)據(jù)對(duì)模型的精度進(jìn)行校核,而后借助宏觀(guān)靜態(tài)OD矩陣拆分的方法將其應(yīng)用到Cube Avenue中觀(guān)動(dòng)態(tài)仿真平臺(tái)上,使得研究區(qū)域具有宏觀(guān)和中觀(guān)兩套評(píng)價(jià)體系,實(shí)現(xiàn)“靜態(tài)動(dòng)態(tài)分配互相結(jié)合、宏觀(guān)中觀(guān)模型相互支撐”的靈活中觀(guān)交通模型技術(shù)方法,一定層面上削弱了因平臺(tái)差異性帶來(lái)的建模難度,更加貼近交通實(shí)際。本文最后將宏觀(guān)和中觀(guān)指標(biāo)進(jìn)行橫向比較,并對(duì)基于中觀(guān)交通模型的交通方案進(jìn)行拓展分析,既體現(xiàn)了中觀(guān)模型的優(yōu)勢(shì)又指出其在方案測(cè)試方面的實(shí)用性。研究成果建立了中觀(guān)動(dòng)態(tài)交通分配模型,提高了中觀(guān)模型建模的系統(tǒng)性和連續(xù)性,彌補(bǔ)了宏觀(guān)靜態(tài)模型對(duì)現(xiàn)狀交通運(yùn)行特征反映不足的缺點(diǎn),使得模型分析結(jié)果更直觀(guān),與現(xiàn)狀結(jié)合更為緊密,實(shí)現(xiàn)了交通方案微觀(guān)指標(biāo)的量化評(píng)估,為支持精細(xì)化交通設(shè)計(jì)方案決策提供了一定參考。
[Abstract]:Intelligent Transportation system (ITS) is the development direction of traffic in the future. Simulation technology is an effective means to study traffic system. The successful construction of urban traffic simulation model can provide a platform for testing and evaluation of traffic plan and decision. Urban traffic planning has a strong support role. Urban road traffic flow is a complex network traffic flow, and urban land resources are relatively limited, the traditional macro-demand forecasting model can not meet the fine requirements of traffic planning and management. Therefore, it is necessary to establish a traffic model that meets the requirements of fine design. In this paper, the advantages and disadvantages of macro, micro and meso traffic simulation techniques are compared. Based on this, the advantages of meso traffic model are expounded, and the importance of building mesoscopic simulation model of urban road traffic is brought forward. In this paper, the method and steps of establishing mesoscopic traffic model based on macroscopic inheritance method are put forward. The mesoscopic sub-zone model is extracted from Xi'an urban traffic model based on Cube Voyager platform, and the accuracy of the model is checked with the traffic measurement data of Xi'an High-tech Zone. Then it is applied to the Cube Avenue mesoscopic dynamic simulation platform with the help of the method of macro static OD matrix splitting, which makes the research area have two sets of evaluation systems: macroscopic and mesoscopic, and realize the combination of static and dynamic distribution. The technical method of flexible meso-traffic model, which supports each other, weakens the difficulty of modeling caused by the platform difference, and is closer to the traffic reality. Finally, the macro and mesoscopic indexes are compared horizontally, and the traffic scheme based on mesoscopic traffic model is expanded and analyzed, which not only embodies the advantages of meso model but also points out its practicability in scheme testing. The research results establish the mesoscopic dynamic traffic assignment model, improve the systematization and continuity of the meso-model modeling, make up for the shortcomings of the macroscopic static model to reflect the current traffic operation characteristics, and make the model analysis results more intuitive. Combined with the present situation more closely, the quantitative evaluation of traffic scheme micro-index is realized, which provides a certain reference for supporting the detailed traffic design scheme decision.
