[2020·ÄϲýÊÐÖصãÖÐѧ¸ßÈýÄ꼶¶Î¿¼ÊÔÌâ]As life in cities worldwide becomes more expensive, urban designers are using modern technology to help citizens avoid traffic jams, and shorten the time needed for bus waiting and other things. Technology is also used to cut costly waste.

In Santander, a Spanish port city, parking is easy to find. As one car drives away, an underground sensor shows that a parking space is now free. 400 sensors send messages to signs on streets, and GPS devices direct drivers to the nearest available parking spaces, reducing traffic jams. Trash is collected only when the bins are full and bus stop signs show exactly when the next bus is coming. The public parks are watered only when the soil gets dry. All this is made possible by 20,000 sensors installed on buildings, street posts and even buses. They are part of the “smart city” project, launched by the University of Cantabria seven years ago.

University researchers like Luis Munoz regularly meet with locals to discuss how to make their city even smarter. “They propose their ideas and sometimes even develop them by themselves. Here, we give them the opportunity to see these ideas happen in real life£¬” said Munoz. For example, the university helped a woman create an app that outlines the easiest route for walking with a baby stroller. Another provides information to residents about their water consumption and sends an alarm to their phone if there is a leak.

The Santander smart project is attracting the attention of larger cities in Europe and elsewhere that are looking for smart solutions to urban problems.
