At TSA we are piloting a variety of innovations at the checkpoint to
improve security by focusing on people, technology and process.
In the process arena, TSA launched a self-select lane pilot this week in
Salt Lake City, Utah. The self-select lane is aimed at enabling
travelers to select a lane customized to their pace. Because the pilot
is in a region of the country where skiing is a way of life, TSA modeled
the lanes after well-known ski icons: green for beginners, blue for
intermediate and black for expert.
In the TSA version, the green lane is for families traveling with
children or people who need special assistance. These folks may not
travel that often and need extra help with the procedures and assistance
navigating security. The blue lane is for casual travelers who are
somewhat familiar with the procedures and have multiple carry-ons. The
expert, or black diamond lane is for those who know the procedures well
and always arrive at the checkpoint with appropriate items removed and
limited carry-on luggage. The security standard is the same no matter
what lane you choose. However, efficiency is increased by allowing
passengers to proceed at their own pace.
