A fleet of driverless sweeper trucks, said to be the first of its kind in the world, has been put on a trial run at an industrial park in Shanghai.

　　世界首支無人駕駛清潔車隊亮相，現已在上海一工業園區投入試運行。

　　Designed and developed by Shanghai-based firm Autowise.ai, the fleet – it comprises 6-meter-long and 3-meter-long vehicles – was tested at the Tus-Caohejing Science Park in Shanghai.

　　由上海仙途智能公司(Autowise.ai)設計研發的清潔車隊，包括一輛6米長和一輛3米長的清潔車。此次測試在上海啟迪漕河涇科技園進行。

　　The unmanned vehicles self-activate every night at 2 am to clean the roads before dumping the trash and returning to the parking space.

　　無人駕駛清潔車每天凌晨2點自動啟動，清理道路，然后傾倒垃圾并返回相應的停車位。

　　The cleaning trucks, which can detect traffic lights, roadside barriers and deal with other traffic conditions, are operating at a reduced speed and only within the designated region during the test period.

　　這些清潔車輛可以檢測到交通信號燈，路障，并能處理其他交通狀況，測試期間只以低速在指定區域運行。

　　According to Ye Qing, the co-founder of the company, the fleet can be easily mass produced as the hi-tech sensors used cost just 300,000 yuan ($47,500).

　　公司聯合創始人葉青(音)表示，清潔車隊所用的高科技感應器成本僅為30萬元(約4.75萬美元)，因此很容易實現批量生產。

　　Ye added that driverless technology has huge potential in the street cleaning business because they would be able to perform under the same conditions as conventional sweeper trucks currently do – on fixed routes and in the wee hours of the morning when traffic is light.

　　葉補充道:無人駕駛科技在道路清潔方面有巨大潛能，是因為他們同樣可以像傳統的清潔車般，在固定路線和凌晨交通不繁忙的時候工作。
