ABSTRACT In the rapid development of national economy in the era of city traffic is the important part the taxi industry has entered a rapid development period. In the process of development to arise out of the various management problems are also real before the taxi industry management of the government and enterprises39。 GPS 與 GIS 的結(jié)合，主要是應(yīng)用于 GPS 導(dǎo)航方面；而 GPS、 GIS 和 GPRS 三者的結(jié)合，則往往應(yīng)用于集成系統(tǒng)，車(chē)輛防盜與監(jiān)控、車(chē)輛調(diào)度等項(xiàng)目中。出租車(chē)行業(yè)作為直接面向廣大人民群眾的一個(gè)服務(wù)性行業(yè)，由于其運(yùn)營(yíng)的車(chē)輛分布在城市道路的各個(gè)地方，因此所涉及到的范圍比較廣，對(duì)社會(huì)的影響也比較大。對(duì)本論文所涉及的研究工作做出貢獻(xiàn)的其他個(gè)人和集體，均已在文中以明確方式標(biāo)明。. .. 工程碩士學(xué)位論文 二○一二年十月 基于 GPS 的城市出租車(chē)智 能管理系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn) 姓 名： 學(xué) 號(hào)： 所在院系：軟件學(xué)院 職業(yè)類(lèi)型：工程碩士 專(zhuān)業(yè)領(lǐng)域：軟件工程 指導(dǎo)教師： 校外導(dǎo)師： . ..
