Every vehicle is equipped with a “help” button which instantly puts the passenger in audio and visual contact with a network operator, who can provide assistance in an emergency. If necessary, the operators can redirect a vehicle to a different station or to waiting security personnel. This helps to ensure passenger safety. Additionally, all elements of the system — vehicles, guideway, and stations — are covered by CCTV.
