Nowadays, for the sake of the environment and self-health, more and more people are encouraged to use bikes. However, with bikes prospering, some problems appeared, such as the lack of infrastructures and regulations of speeding. According to NYPD reports, bike crashes have caused 23 death. To improve riding safety and make it more enjoyable, government and commercial corporations are trying to utilize technology to build bike lanes.

In riding safety. Copenhagen has reached significant progress. Green Wave, designed by Albert Street project group, is a series of traffic light sequences coordinated to give road users a smooth passage along a stretch of road. By traveling at a certain speed, users can “ride” the wave of green lights, moving along without being stopped at each intersection. The secret is that sensors are hidden in each light, which can look into average rider power and traffic light timings. Thus, if the light is green, it means the rider’s speed is between optimal speed range and the rider can exactly make it through this intersection. Otherwise, you’d better speed up.

Green waves can also act as an alert to warn right-turning truck drivers of cyclists in the bike lane, thereby preventing right-turn accidents (where truck drivers have low visibility). “Ooh, hang on a minute — there could be a bike.” The light activated by cyclists crossing on green improves awareness of the lorry drivers.
Imaging all light turns green stretching in the ground with you riding, I guess it is enjoyable and gives people a good mood. Meanwhile, the green wave makes riding safer and more appealing for citizens to get on their bikes.
