Look at the map above and locate the time point at or before the stop where you will end your trip. Turn to the schedule and locate the column for your destination time pint and read down the table to the scheduled time at or before the time you want to arrive. Now read backwards across the table from your destination column to the column under your starting point. This gives you the time your should start your trip. Sometimes buses from more than one route stop at the same bus stop.
Some routes also travel vie alternate streets and have different final destinations.
When you board the bus, check that you are on the right route with the destination you want. Above the windshield of each bus is a sign showing its route number and final destination. Be at your stop 3-5 minutes early to be sure to catch the bus you need.
