【正文】 c traffic simulation software VISSIM theoretical basis, based on the model in the Haidian Island, Haikou City Dian Kun intersection traffic simulation. Dian Kun intersection traffic conditions collected survey data, analysis of its intersection traffic operation status quo. VISSIM simulation, and analysis of simulation data, the evaluation of the intersection capacity, traffic delays, queue length and road traffic indicators. The traffic design improvements and optimization Dian Kun Road intersection to make reasonable suggestions to solve Dian Kun intersection unreasonable urban traffic planning and design. The results show that the city39。s road intersections by simulation to optimize traffic flow guidance, help to solve the intersection traffic congestion, improve traffic travel service levels. VISSIM traffic simulation in practical applications, effectively solve the practical problems of urban transport in the plex traffic conditions. This is a new method of urban intelligent transportation system automation, digitization important. Key words: traffic simulation。 VISSIM。 intersection。 traffic flow 目錄 1 緒論 ........................................................................................................... 1 2 仿真軟件概述 ........................................................................................... 2 3 交通仿真原理 ........................................................................................... 2 系統(tǒng)模型 .......................................................................................... 2 基礎(chǔ)數(shù)據(jù)建模 .................................................................................. 3 車輛加、減速函數(shù)建模 ........................................................ 3 期望車速分布建模 ................................................................ 4 駕駛行為 .......................................................................................... 5 4 交通仿真實(shí)例 ........................................................................................... 6 交叉口交通現(xiàn)狀 .............................................................................. 6 交叉口路網(wǎng)建模 .............................................................................. 7 交叉口交通量 ................................................................................. 9 交叉口信號(hào)控制 ............................................................................ 10 信號(hào)控制原理 ...................................................................... 10 信號(hào)相位方案 ...................................................................... 10 5 交叉口交通仿真評(píng)價(jià) ............................................................................. 12 行駛時(shí)間 ........................................................................................ 12 行車延誤 ........................................................................................ 13 排隊(duì)長(zhǎng)度 ........................................................................................ 14 6 結(jié)語 ......................................................................................................... 15 致謝 ............................................................................................................... 16 參考文獻(xiàn) ....................................................................................................... 17 實(shí)驗(yàn)附件 ....................................................................................................... 18 基于 VISSIM 的交叉口交通仿真 研究 1 1 緒論 交通仿真技術(shù)在 20 世紀(jì) 60 年后逐步興起，采用計(jì)算機(jī)交通仿真 數(shù)字模型來反映復(fù)雜道路交通現(xiàn)象的交通分析技術(shù)和方法。交通仿真是智 能交通運(yùn)輸系統(tǒng)的一個(gè)重要組成部分，是計(jì)算機(jī)技術(shù)在交通工程領(lǐng)域的一個(gè)重要應(yīng)用，能夠動(dòng)態(tài)地、準(zhǔn)確地仿真交通流 等 各種交通現(xiàn)象，有效地進(jìn)行交通規(guī)劃、交通組織與管理、交通運(yùn)輸流量合理化等方面的研究。 本文基于 VISSIM 交通仿真軟件理論 模型 對(duì)城市道路交叉口進(jìn)行交通仿真研究。首先根據(jù) VISSIM 的理論基礎(chǔ)來建立交叉口的交通運(yùn)行狀況指標(biāo)，其次對(duì)城市道路交叉口進(jìn)行實(shí)地交通調(diào)查，利用 VISSIM 對(duì)所調(diào)查行車數(shù)據(jù)進(jìn)行仿真， 通過虛擬現(xiàn)實(shí)技術(shù)手段， 再現(xiàn)交叉口交通狀況，分析交叉口的各項(xiàng)行車通行能力 情況，對(duì)某個(gè)位置交通出現(xiàn)擁堵、通行能 力低下應(yīng)該 采用什么樣的解決方案來疏導(dǎo)交通 ？ 避免 交叉口 出現(xiàn) 擁堵排隊(duì)過長(zhǎng)等交通故障發(fā)生。 ?？谑泻５閸u甸昆路口作為城市道路交叉口連接海甸島和世紀(jì)大橋的重要路網(wǎng)通行節(jié)點(diǎn)，關(guān)系到海甸島整體道路交通服務(wù)水平，其交通現(xiàn)狀無法滿足當(dāng)前城市道路智能交通系統(tǒng)發(fā)展需求，
