春節是中國最重要的傳統節日。每逢春節,中國人都會回家與家人團聚。近年來,由于越來越多的中國人離開家鄉到外地學習或工作,春節前后就會出現春運高峰(the Spring Festival travel rush)。每年此時,大量乘客涌入火車站、汽車站和機場,公共交通承受著巨大的壓力。為時40天的春運堪稱世界上最大規模的年度遷徙(migration)。為了確保每位乘客旅途順利,運輸部門(transportation authorities)就得提供更為優質的服務。
The Spring Festival is the most important traditional festival in China during which the Chinese return home to reunite with their family members. In recent years, as more and more people leave their hometowns to study or work elsewhere, the Spring Festival travel rush has appeared around the Spring Festival. During this period every year, volumes of passengers rush to railway stations, bus stations as well as airports. Hence public transportation is under great pressure. Faced with the 40-day Spring Festival travel rush known as the biggest annual human migration in the world, transportation authorities have to optimize their services to ensure a smooth journey for every passenger.
