After our information sharing platform has been built, you can download our app, which includes a map of the sidewalk. You can use it both to assist you in your travels and to help keep the system up to date and accurate. Your contribution is crucial, not only to help everyone get around, but also to keep them safe. You can see some sidewalk safety markings on the map, and if a piece of the map is orange or even red, please tell government officials immediately that it may be troublesome or even dangerous for non-professionals, and if you see one that meets the orange or red criteria but is not marked, you can take a picture and upload the time-stamped information in a timely manner, and the reviewed information will be milked by the system and updated immediately, it’s that simple!
