Realizes the longitudinal relationship between models by using object - oriented programming language ; 2 ) sets forth the function and software design in detail , and analyzes entities of the system . realizes the randomness of traffic flow and constructs vehicle arriving model , vehicle movement model on road segments and vehicle movement model on intersections , so completes the kernel part of traffic simulation ; 3 ) uses 3d modeling software - multigen creator and real - time simulation software - vega to build up the 3d virtual environment of microscopic traffic simulation , and drives dynamic entities such as driver - vehicle units and traffic lights in static scenes ; 4 ) studies the characteristic of checkerboard system of street layout , analyzes and decomposes the system to deduce a certain simplification method . and researches the application of urban traffic route choice 論文主要工作如下: 1 )利用面向?qū)ο蠹夹g(shù)分析交通仿真系統(tǒng)模型之間的橫向關(guān)系和交互作用,研究靜態(tài)實(shí)體的狀態(tài)變化和動(dòng)態(tài)實(shí)體的運(yùn)動(dòng)規(guī)律;利用面向?qū)ο蟮某绦蛟O(shè)計(jì)語(yǔ)言實(shí)現(xiàn)系統(tǒng)中模型的縱向關(guān)系; 2 )詳細(xì)闡述交通微觀仿真系統(tǒng)的功能設(shè)計(jì)、軟件設(shè)計(jì),分析仿真系統(tǒng)中的實(shí)體;實(shí)現(xiàn)車流的隨機(jī)性,建立車輛的到達(dá)、車輛在路段上的行駛過(guò)程、車輛通過(guò)交叉口的行駛過(guò)程等模型,完成交通仿真的核心內(nèi)容; 3 )利用三維建模軟件multigencreator和實(shí)時(shí)仿真軟件vega建立交通狀態(tài)微觀仿真的三維虛擬環(huán)境,在靜態(tài)視景中驅(qū)動(dòng)駕駛員-車輛單元、信號(hào)燈等動(dòng)態(tài)實(shí)體; 4 )研究棋盤式道路格局的特點(diǎn),從理論上分析并分解系統(tǒng),得到一定的簡(jiǎn)化依據(jù),進(jìn)一步研究城市交通路線選擇的應(yīng)用。
