One Arizona city plans to use GPS-based technology to move emergency vehicles more efficiently through traffic.

In an upcoming pilot, Tempe, part of the Phoenix metro region, will partner with digital transportation technology company LYT to add GPS-based signal technology at 12 intersections. The new system will give emergency vehicles green lights as they approach the signal, Tempe Senior Civil Engineer Ellie Volosin said via email.
