I want to design a app for finding nearby public services such as public restrooms, hospitals, parks and police stations. Government organizations can get access to the searching history(which should be anonymous) and the ratings/comments/feedbacks people gave after finding their destinations.(Was the intrustion clear? Was the service good? Did they have to walk too long a distance?) Thus it can help city designers to better locate where certain types of public service should be available or of better quality in order to satisfy the specific needs of the local people.
