My name is Yu, and I live in a smart city. On a school morning, I check the bus app before I leave home. It shows that Bus 12 will arrive in six minutes. I walk to the stop and do not need to wait for a long time.
On the bus, a small screen tells us the next stop. The bus driver also gets a message when the road is very busy. I can see the traffic information on my phone, so I tell my teacher that I may be a few minutes late. The information helps me plan my time.
After school, I walk through a park near my home. A smart trash bin has a light that tells workers when it is full. Because workers receive the message early, the park has fewer overflowing bins. People also find it easier to keep the park clean.
At home, smart lights turn off when no one is in a room. My family uses less electricity, and the lights turn on again when we enter. These small tools do not make life perfect, but they save time and energy. In my smart city, technology quietly helps people make better choices every day.
