The Los Angeles County Metropolitan Transportation Authority (LACMTA) has announced the LA subway will soon be using body scanners to screen passengers for weapons and explosives.
The transport authority will be the first mass transport system in the US to adopt the technology.
The scanning equipment made by Thruvision will be placed at the bottom of escalators; scanning more than 2,000 passengers an hour and detecting suspicious items from up to 32ft (10m) away.
The cameras can detect items that have been hidden by observing a person’s body heat through their clothing. Concealing an item under clothes blocks body heat from being emitted.
Human operators can examine the captured images and decide if further investigation is required.
Passengers are not obliged to go through the screening but will be banned from travelling if they refuse to do so.
Furthermore, Thruvision’s technology is going to be used on a pop-up basis instead of being installed permanently.
