Find out where you want to go and what time you want to get there and then determine which bus routes serve your destination point and starting point. Check the route schedules online or pick up a schedule at a convenient location (please see above).
Look at the schedule serving your destination first, and find the time point on that schedule nearest your destination. Time-points are landmarks or intersections that show estimated arrival times of the bus. Each schedule shows a map of the route, and time points. In most cases, you can get on and off the bus at bus stops between these time-points (there are hundreds of bus stops located along METRO routes).
Then check the schedule for where you want to begin your trip to determine when you need to catch the bus.
