Stay with other people. Stand away from the curb. If possible, sit close to the driver in an aisle seat. Notify the driver immediately if anyone bothers you or even acts suspiciously. Don't accept a ride to your destination from a stranger.
Subways Be alert.
Wait near the ticket booth, away from the platform edge. Don't exit at your stop if it's not well lit. Stay on until you reach a better stop. If you think you're being followed, get off only at a busy stop. Go directly to the ticket booth and ask the cashier to call the police.
