阅读短文并回答下列问题
Every driver loves sailing through a ries of green lights without having to stop and wait at a traffic light. Now, thanks to artificial intelligence, German rearchers have found a way to reduce time spent at interctions （十字路 口 ）.
Called the KI4LSA project and funded by the Ministry of Transport and Digital Infrastructure, the innovation is being tested. Scientists first studied algorithms （算法）taken from a busy interction to learn about traffic patterns and where improvements were most needed. There is a great necessity to speed up waiting times at interctions as conventional methods are inflexible, according to the Fraunhofer Institute.
The new AI method us radar nsors and high-resolution cameras to interpret traffic patterns in real-time. They can determine the speed of traffic as well as waiting times and combine this with lf-learning algorithms. Scientists are currently trying this out at a busy interction in Lemgo, Germany, with encouraging results.
The intelligent lights are said to improve traffic flow by 1（） to 15 percent, which results in money saved; the EU estimates that traffic jams create economic damage that adds up to 100 billion euros a year. Aside from reducing commuting time, the traffic lights will reduce noi and CO2 emissions from cars idling at interctions.减肥运动快速燃脂
Another exciting development in this rearch is the K14PED project, which studies pedestrians crossing interctions. Using AI, rearchers can identify how many people are waiting at a pedestrian crossing and whether some of the people will need extra time to cross the street. Using a 3D points cloud, they can tell if someone has disabilities or is elderly without identifying the individual. Since pedestrian buttons that are prently at interctions cannot determine if some people have special needs or are elderly, this i
s a real win. Such a needs-bad system could reduce pedestrian waiting time by 30 percent, which could then decrea jaywalking （舌L穿马路）by 25 percent.
Testing will be done until the summer of 2022 in the German towns of Lemgo and Bielefeld, with rearchers optimistic that it will be adopted by many countries. This technology is exciting news for pedestrians and drivers alike. It encourages safety, protects the environment, and may even give you more time to enjoy your morning coffee before heading off to work!
