LITTLE ROCK, AR- A joint effort with the Highway Department and the City of Little Rock that could decrease your travel time through that intersection by as much as 50%.
New cameras added at the interchange have motion detectors and keep track of how many cars are at each traffic signal.
They then adjust the time of the lights accordingly, for example during rush hour when the majority of traffic is running east and west on 630.
Those signals might stay green more than 80 seconds longer than usual.
"You go up there you're sitting on the side street," said Bill Henry with the city. " You ask 'why am I sitting here with no traffic?' What this does is it see there's no traffic so it goes back to side street and moves that and reduces overall delay and intersections. "
Henry said this is some of the most advanced technology available to handle traffic.
