I’m looking for good practice example(s) of social responsibility policies and practices of a transport system company, in a major city of a developing country. Ideally, a company that runs an extensive network of busses, trains, trams, etc in a major city that is polluted, dirty, hard to live in, and riddled with corruption. I’d like to find examples of such companies and read about how they deal with such issues and what good practices they implement. Could you please point me to any such examples?
