交通運輸的發展帶來了巨大的變革, 包括全球經濟的擴張, 旅行時間的減少和舒適程度的提高。

Changes in infrastructure work too; recently LA became the first city to synchronize every street light, causing lights to make automatic adjustments based on flow, which has reduced travel time by 14%.

基础设施的变化也会起作用。最近，洛杉矶成为第一个实现交通灯同步的城市，使得交通灯根据流量自动调整，减少了14%的出行时间。
