Today I will talk about the topic of sustainable cities and communities. We need to build modern, sustainable cities. We need new smart city planning that creates safe, affordable, and resilient cities. with environmentally friendly and culturally inspiring living conditions I am interested in Target 11.2, Affordable and sustainable transport system. It addresses providing access to a safe, affordable, accessible and sustainable transportation system for all. improve road safety. I will mention the zebra crossing. When talking about a zebra crossing, which is an area where pedestrians are allowed to cross the road. At the same time, every car When reaching the area, the vehicle must slow down and stop to give way to pedestrians crossing the road. But it's still not safe. Because nowadays there are still news stories about accidents that happen to people crossing a zebra crossing that can often be heard. Most of them are caused by the negligence of cars or motorcycles that do not slow down to give way to pedestrians crossing. causing injuries. It made me think of building a zebra crossing signal. That will send a warning signal to cars that have a warning system that warns that someone is about to cross the road. Also included are gas and temperature sensors. In order to reach the pollution conditions in that area as well Make people in the area have protection from pollution such as wearing masks. or help reduce pollution in the community in that area.
