桃園公車動態系統10月初大升級,桃園市政府交通局表示,新版系統將導入AI演算法,並結合Google Maps即時路況資訊,提升公車預估到站時間的精準度,相較舊版主要依據歷史資料推估,新系統目前轉換進度約4成,預計10月初完成全面切換,到站資訊準確率可望由現行約80%提升至90%以上。

交通局說明,此次新舊系統轉換須由客運業者逐車進行車機設定及切換,目前整體轉換進度約41%,預計9月29日達95%、10月4日完成100%全面切換。

請繼續往下閱讀...

另,由於現仍有部分車輛透過舊系統回傳GPS資料,加上新舊系統資料轉換及同步作業,近期部分公車動態資訊可能出現短暫誤差,包括班次未顯示、車輛位置或預估到站時間異常等情形。

交通局表示,目前已針對異常路線逐一比對班表、車輛及GPS資料,並會同客運業者加速完成車機切換及資料修正,同時持續調整新系統預估到站模型,預計10月4日前完成相關處理;而隨著車機陸續切換、資料持續校正及系統運作穩定,公車到站資訊準確性已逐步提升,個別異常班次也將持續查核處理。

至於使用非官方公車APP查詢資訊,交通局補充,多數第三方APP是透過交通部TDX平台取得公車動態資料,9月新系統測試切換初期,新系統與TDX間的資料介接也同步調整,曾影響部分資訊傳遞,經確認及調整後,目前已可正常取得最新資料,使用TDX資料的第三方APP無須因此次桃園公車動態系統升級而改版。

交通局表示,將持續掌握各管道公車資訊,確保新系統完成切換後,提供民眾更即時、準確的公車動態資訊。

Open Questions

  • 新系統長期維護成本為何?
  • 是否所有客運業者車輛都能同步升級?
  • 升級後是否會整合其他智慧交通服務?

Harbin to Yichun high-speed railway officially opened for operation

The Harbin to Yichun high-speed railway was officially opened for operation on the 28th. It has a total length of 318 kilometers, a design speed of 250 kilometers per hour, and nine stations. The fastest journey from Harbin to Yichun is 1 hour and 46 minutes, which is a significantly shorter travel time than the past 7 hours by train and 4 hours by car. This line is the northernmost high-speed railway in my country and the first high-speed railway in China that passes through the alpine island-shaped permafrost area. It connects the ecological scenic spots in the hinterland of Xiaoxing'anling to the high-speed railway network and promotes the development of forest health care, study experience, ice and snow tourism and other industries.

Google Space Data Center’s first test reveals heat dissipation bottleneck: 4 TPUs can only run at full speed for 15 minutes

Google plans to launch an MVP satellite equipped with four AI chips on October 1 to test the feasibility of a space data center. However, the first test showed that the chips can only operate at full power for about 15 minutes before shutting down to cool down. The heat dissipation problem has become a key bottleneck in space computing, rather than the expected launch cost.

Smart economy has become a strategic variable to seize the initiative in future development

The article pointed out that artificial intelligence is affecting economic and social development at an unprecedented speed, promoting the transformation from "technological variables" to "economic increments". Developing an intelligent economy is an urgent need to seize the commanding heights of global artificial intelligence and promote high-quality development. The scale of my country's smart economy has expanded rapidly, its quality has jumped significantly, its structure has continued to be optimized, and smart industrialization and industrial intelligence have been coordinated. By the end of the "15th Five-Year Plan", the scale of artificial intelligence-related industries is expected to reach more than 10 trillion yuan, and the smart economy will become an important growth pole.
