10、w,especially at rush hour.At 9:30am,the full red/yellow/green signal cycle might be 140 seconds.By 9:33am,a burst of additional traffic might push it to 145 seconds.Less traffic at 9:37am could push it down to 135.Just like the traffic itself,the timing of the signals changes.That is by design.Belle

11、vue,a fast-growing city just east of Seattle,uses a system that is gaining popularity around the US:intersection(十字路口)signals that can adjust in real time to traffic conditions.These lights,known as adaptive signals,have led to significant declines in both the trouble and cost of travels between wor

12、k and home.“Adaptive signals can make sure that the traffic demand that is there is being addressed,”says Alex Stevanovic,a researcher at Florida Atlantic University.For all of Bellevues success,adaptive signals are not a cure-all for jammed roadways.Kevin Balke,a research engineer at the Texas A&M

13、University Transportation Institute,says that while smart lights can be particularly beneficial for some cities,others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference.“Its not going to fix everything,but adaptive signals have some benefit
