The US Transportation Security Administration (TSA) and the Los Angeles County Metropolitan Transportation Authority (Metro) have partnered to roll out a new advanced portable passenger screening across the transit system.

The new Thruvision TAC-TS4 portable terahertz millimetre wave passenger screening technology is effective to detect the presence of person-borne, improvised explosive devices and other security threats.

Following the completion of a series of testing at the stations, Metro purchased several such devices, which will now be placed across various locations.

TSA administrator David Pekoske said: “TSA applauds the leadership of LA Metro for its proactive efforts to evaluate, procure and use state-of-the-art technology designed to detect potential threats to the transit system.

“This new technology will augment our already aggressive safety and security measures and help us proactively deter potential attacks to our system.”

“TSA is pleased to have been a partner during the evaluation and testing process, which ultimately led to the purchase of a recommended system to help detect and deter potential acts of terrorism while keeping the travelling public safe.”

Thruvision is equipped with software that screens passengers without disrupting normal foot traffic movement.

The device identifies any concealed object by detecting any disruption or blockage in the flow of natural waves produced by the human body.

It subsequently generates generic avatars and creates a black spot on the particular area of the body or marks it with a colour indicator.

Accordingly, Thruvision enables the security personnel to track the concerned person and take future action when such suspicious events occur.

TSA noted that the device, which is capable of detecting metallic and non-metallic objects, does not emit radiation during the screening.

LA County supervisor and Metro Board chair Sheila Kuehl said: “This new technology will augment our already aggressive safety and security measures and help us proactively deter potential attacks to our system.”

Over the last year, Metro tested the Thruvision technology at its 7th Street/Metro Center Station.
