Throughout the week, Emory provides shuttles to a number of different routes on and off campus, making it fairly convenient to get to and from class in a relatively short time. The shuttles run constantly during the week and are very convenient, especially for off-campus housing, such as Clairmont. However, on the weekends, the shuttles are incredibly slow and inconsistent. Emory provides an online application from which you can see where the shuttles are, as well as their expected departure/arrival times, but these times are rarely accurate and can be off by 10 to 20 minutes at times. If you are trying to get to main campus or other stops on the shuttle routes during the weekend, taking your own car or finding a ride with a friend is your best bet.
Rush hour in Atlanta is brutal and one of the worst traffic cities in America. Public transportation off campus is rather convenient and generally inexpensive compared to a cab. The MARTA shuttle services the airport and most of the major concert and/or sporting event venues in the city. You can hop on a MARTA shuttle and make the trip downtown for just a few bucks, compared to dropping $20 to $30 for cab fare. However, during peak weekday and weekend hours, traffic is terrible, and the MARTA shuttles can become extremely crowded and uncomfortable. Always plan ahead when you are making a trip downtown to figure out the best way to get there, and you will save yourself a lot of time, some major headaches, and also some cash.
