PLANO, Texas, Sept. 1, 2020 – The North Texas Tollway Authority (NTTA) has initiated a thermal camera
pilot program to detect and deter wrong-way drivers. Signs pictured below are located on the south end
of the Dallas North Tollway.
Video of flashing signs, thermal cameras and generic thermal camera imagery, can be found here.
Using heat emitted from a vehicle, thermal cameras monitor the regular flow of traffic. When a vehicle
drives in the incorrect direction, signs flash “Wrong Way” – warning a driver to correct their error.
NTTA’s Safety Operation Center receives an alert, staffers notify DPS Highway Patrol and overhead
message signs warn drivers of a wrong-way driver on the road ahead.
“Safety is NTTA’s number one priority,” said Assistant Executive Director of Infrastructure Elizabeth
Mow. “We will monitor this pilot program, assess results, make improvements and determine if it can be
used on other NTTA roads.”
