1、長沙理工大學(xué)碩士學(xué)位論文城市公交線網(wǎng)優(yōu)化研究姓名:李發(fā)申請學(xué)位級別:碩士專業(yè):交通運(yùn)輸規(guī)劃與管理指導(dǎo)教師:劉清君20090207摘要城市公共交通是城市賴以生存的重要基礎(chǔ),是城市整體發(fā)展中不可缺少的物質(zhì)條件和基礎(chǔ)產(chǎn)業(yè),城市公共交通線網(wǎng)是提高公交系統(tǒng)服務(wù)水平,提高公交競爭力的基礎(chǔ),本文在對國內(nèi)外公交線網(wǎng)優(yōu)化的研究歷史和現(xiàn)狀進(jìn)行分析與評價的同時,系統(tǒng)分析了公交線路優(yōu)化的方法,運(yùn)用功能層次分析對城市現(xiàn)狀公交樞紐、公交線網(wǎng)進(jìn)行分析,同時對線網(wǎng)優(yōu)化目標(biāo)及約束條件進(jìn)行研究,建立公交線網(wǎng)優(yōu)化模型和優(yōu)化方法,結(jié)合具體項(xiàng)目的需求,對既有公交線網(wǎng)進(jìn)行優(yōu)化和調(diào)整。本文針對公交線網(wǎng)功能層次的紊
2、亂現(xiàn)狀,在公共交通需求預(yù)測的基礎(chǔ)上,綜合分析城市用地布局結(jié)構(gòu)、客流走廊、道路網(wǎng)結(jié)構(gòu)等要素,對現(xiàn)狀公共交通的樞紐結(jié)構(gòu)和公交線網(wǎng)進(jìn)行功能層次分析,結(jié)合線網(wǎng)優(yōu)化目標(biāo)及約束條件,對既有線路進(jìn)行分析與評價,然后針對城市公交線網(wǎng)的優(yōu)化問題,從提高乘客服務(wù)水平以及公交企業(yè)的利益角度,建立求解優(yōu)化模型,運(yùn)用遺傳算法,建立全新公交路線,將此路線結(jié)構(gòu)與之前層次分析的現(xiàn)狀公交路線相結(jié)合,完善和優(yōu)化公交線網(wǎng)。最后,文章運(yùn)用所求公交線網(wǎng)優(yōu)化方案結(jié)合現(xiàn)有公交路網(wǎng)提出的調(diào)整方法,以邵陽市為例進(jìn)行了相關(guān)的算例研究。關(guān)鍵詞:公交線網(wǎng);優(yōu)化:功能層次分析;遺傳算法ABSTRACTUrbanpublict
