中文摘要 | 適當的軌道運輸統計資料標為政府、一般大眾、以及鐵路機構所需要之重要資訊。目前在我國及在其他國家,軌道運輸系統在運轉過 程中產生的資料,大部份經由統計資料或指標等資訊濃縮形態流向外 界使用者。在此作法下,鐵路機構各自產生之資料不易融合,而鐵路 機構亦不易控制資訊之流向。因此,即便指數之計算方式與實際需求 僅有小幅之差異,資料使用者仍需請求鐵路機構重新提供依需求客製 化之指數,而鐵路機構則常採取保守態度以保護掌控資料流向之能 力。此外,相似指數間微小的定義差異又常成為資料比較之重大困難。 為此本研究提出建立關聯式資料平台作為所有軌道運輸系統共 同資料中心之構想。鐵路機構上載詳細的運轉資料,如所有車次之表 訂與實際到、離站時分紀錄、所有乘客在系統中旅行過程之紀錄、及 其他項目。資料平台則對授權之使用者及一般大眾提供客製化之統計 與指標,而所提供之資料內容與解析度則視授權程度而異。本系統亦 可自動定期產生並傳送報表。此一系統可望消除因為指標定義分岐而 產生之應用障礙、為鐵路機構節省可觀的資料處理相關經費及其他資 源、為所有資料使用者提供單一窗口、成為重要而可靠之檔案庫、使 珍貴資料發揮最大效用、並有機會在未來支持不計其數的資料加值應 用。 |
英文摘要 | Appropriate statistics and indexes of railway systems are vital to the government, general public, and even to railway agencies themselves. Currently in Taiwan and in many other countries, most basic data are generated within the railway system during operation, and information flows to outside users through the condensed form of statistics and indicators. Information treated in this process is hard to fuse with each other, and the railway agencies lack the means to control their usage once released, resulting in their reluctance in releasing information. As such, data users have to go back to the railway operators when they need customized statistics, even when their need is already close to those already provided. Moreover, slight differences in the definition of similar indexes frequently make comparison among different railway systems very difficult. In light of these drawbacks, this work proposes the establishment of a relational data platform as a common source of all railway statistics. Under this scheme, railway operators upload detailed records, including the scheduled and actual departing and arrival time of every train service,the travel record of every passenger within the system, environment monitoring data, and others. The system provides customized statistics to authorized users and the general public, where the content and data resolution provided depends on the level of authorization. The system is also able to regularly generate reports and deliver them automatically. We expect that the creation of such a system will eliminate the obstacles resulting from index definition variances, save considerable information-processing related funding and other valuable resources for railway agencies, provide a unified statistic source for all the users, serve as an accurate and reliable data archive, effectively enhance the usability of precious real data, and will be able to support numerous value-adding applications in the future. |
