Accessibility Is Freedom เข้าถึงและเท่าเทียม | Accessible and Equal

In one of my recent fieldworks, I mentioned to the (city development) team the issues with crosswalk that tarnishes and wears out quickly. Most likely from all the pollutants such as dust and dirt. The amount of traffic and the multiple ongoing construction projects are the likely culprit. So I asked them if they could do something about it and keep the crosswalk clean.
