Bus Stops

I live in an area where one of the bus routes passes directly by my apartment complex. This route begins at the Ingram Mall five minutes from my apartment and ends at the Northstar Mall five minutes from the SA Airport. At times I will ride the bus to the larger mall (Northstar) and leave my car parked at home. I noticed that the bus stops are numbered. I called the public transportation department about this, and was told the reason is to give a person clearer directions. When asking for directions, someone would be state where they're coming from and their destination. Then he/she would be to directed to a specific numbered bus stop. Not a bad idea at all ! It worked for me.
