1、長沙理工大學(xué)碩士學(xué)位論文城市多模式公交線網(wǎng)優(yōu)化研究姓名:郭湘申請學(xué)位級別:碩士專業(yè):交通運輸規(guī)劃與管理指導(dǎo)教師:楊明20071105摘要隨著城市經(jīng)濟(jì)不斷發(fā)展,城市交通問題日趨嚴(yán)重,公共交通成為解決城市交通供需矛盾的重要手段。由于現(xiàn)階段存在規(guī)劃主體和執(zhí)行部門的博弈問題,造成多種公交方式之間存在過多的競爭而非合作,使得城市公共交通的不同方式無法有效整合,公共交通系統(tǒng)的吸引力難以提升,居民不同層次的出行需求難以滿足,公共交通系統(tǒng)的整體優(yōu)勢無法得到充分體現(xiàn)?;诖?,本文結(jié)合傳統(tǒng)公交規(guī)劃方法,著重探討了城市多模式公交線網(wǎng)優(yōu)化方法。本文通過
2、闡述單一模式公交和多模式公交的概念及其特性,對多模式公交發(fā)展趨勢以及各種公交方式之間的合作和競爭進(jìn)行分析,在此基礎(chǔ)上確定了多模式公交線網(wǎng)優(yōu)化的目標(biāo),以達(dá)到最短路徑優(yōu)化和換乘結(jié)構(gòu)優(yōu)化。本文建立了多模式公交優(yōu)化的數(shù)學(xué)模型,設(shè)計了最短路路徑搜索算法和換乘最優(yōu)算法,結(jié)合福州案例,最后提出了“先主后次、先粗后細(xì)、分層分級布設(shè)”的多模式公交線網(wǎng)布設(shè)方法。通過對福州公交線網(wǎng)優(yōu)化后結(jié)果進(jìn)行評價,證明多模式公交線網(wǎng)優(yōu)化方法是合理的,能夠取得較好的效果。關(guān)鍵字:公共交通;多模式;最短路徑;換乘優(yōu)化;線網(wǎng)布設(shè)ABSTRACTWiththecontin
