伴随城市蔓延、轨道交通成网、用地开发等发展条件,大城市综合交通环境日益复杂。如何拓展评估边界、深化评估技术、提升评估频率和延伸评估视角成为传统城市交通评估技术体系面临的四个关键问题。首先介绍交通领域大数据的组成、特征及应用情况。通过深度挖掘交通运行产生的多源异构数据,建立集统计、关联、预测于一体的交通大数据分析平台和专题评估子系统,形成面向多层次、多领域应用需求的一体化综合交通模型体系。最后,基于深圳市的应用实践情况,阐述城市交通综合评估技术从城市到区域、从宏观到微观、从静态到动态、从土地到环境的转变。
伴隨城市蔓延、軌道交通成網、用地開髮等髮展條件,大城市綜閤交通環境日益複雜。如何拓展評估邊界、深化評估技術、提升評估頻率和延伸評估視角成為傳統城市交通評估技術體繫麵臨的四箇關鍵問題。首先介紹交通領域大數據的組成、特徵及應用情況。通過深度挖掘交通運行產生的多源異構數據,建立集統計、關聯、預測于一體的交通大數據分析平檯和專題評估子繫統,形成麵嚮多層次、多領域應用需求的一體化綜閤交通模型體繫。最後,基于深圳市的應用實踐情況,闡述城市交通綜閤評估技術從城市到區域、從宏觀到微觀、從靜態到動態、從土地到環境的轉變。

The comprehensive transportation in large cities has become increasingly complicated under de-velopment conditions of urban sprawl, rail transit network and land-use. Thus, how to expand assessment area, improve assessment technology, increase assessment frequency and extend assessment perspective have become four critical issues for the traditional assessment system of urban transportation. This paper first introduces the components, characteristics and application of big data in transportation field. Consider-ing transportation data coming from a variety of sources in different format, the paper establishes a trans-portation big data analysis platform that can integrate data and identify correlation, and the various special assessment subsystems. The developed platform and subsystems can function as a comprehensive transpor-tation model system to accommodate multi-level and multi-field application demands. Finally, the paper elaborates the transition of comprehensive assessment on urban transportation in Shenzhen practice in sev-eral aspects:from urban to regional level, from macroscopic to microscopic views, from static to dynamic states, and from land to environment.
