內(nèi)容簡介

　　大數(shù)據(jù)時代已經(jīng)到來，隨著數(shù)據(jù)的逐步開放，交通領(lǐng)域的研究課題或多或少都要接觸、使用時空大數(shù)據(jù)。交通領(lǐng)域的從業(yè)者迫切需要強有力的工具和技術(shù)應對日益紛雜的交通數(shù)據(jù)。交通是一個交叉學科，交通數(shù)據(jù)分析人才的知識體系需要與數(shù)據(jù)處理、網(wǎng)絡(luò)爬蟲、數(shù)據(jù)可視化、地理信息、復雜網(wǎng)絡(luò)、數(shù)據(jù)挖掘、機器學習等多學科知識深度融合，這也為交通領(lǐng)域的人才培養(yǎng)帶來巨大挑戰(zhàn)。在此背景下，本書針對不同的學習階段與業(yè)務需求設(shè)計了三篇共15章內(nèi)容。基礎(chǔ)篇（第1～5章）梳理Python數(shù)據(jù)分析、網(wǎng)絡(luò)爬蟲、數(shù)據(jù)可視化、地理信息等基礎(chǔ)知識；應用篇（第6～10章）介紹出租車GPS數(shù)據(jù)、地鐵IC刷卡數(shù)據(jù)、共享單車訂單數(shù)據(jù)、公交GPS數(shù)據(jù)等各類時空大數(shù)據(jù)的實際案例應用；方法篇（第11～15章）融匯數(shù)據(jù)挖掘、空間統(tǒng)計、復雜網(wǎng)絡(luò)學科等交叉學科方法，與交通領(lǐng)域的大量實際案例分析結(jié)合，全面梳理總結(jié)交通時空大數(shù)據(jù)所需跨學科技能。本書由淺入深，學科交叉，強調(diào)實踐。對讀者不同的學習階段與業(yè)務需求設(shè)計相應內(nèi)容，全面梳理總結(jié)交通大數(shù)據(jù)科研所需技能，并與交通領(lǐng)域的大量實際案例分析結(jié)合。本書可作為教材也可作為參考工具書，基礎(chǔ)篇定位交通數(shù)據(jù)領(lǐng)域新手入門，應用篇定位有數(shù)據(jù)分析需求的高校學生或社會人士，方法篇定位高校學術(shù)科研人員。
