LAFAYETTE, Ind. (WLFI) — New state of the art technology will help the city with traffic.

The first signal was installed at Wallace and Main streets. 

Sensors were taken out and replaced with a camera system that collects real-time data for the city.

That data is then processed for engineers to analyze.

"What this data gives us is the ability to look at our signal timings to determine if our signal timing is appropriate," said City Engineer Jeromy Grenard. "If there are times of day when we have backups, we'll understand it through this data." 

Grenard said it allows them to see the needs of that particular intersection and would also alleviate the need for someone to do physical traffic counts.

"This is processing in real-time," Grenard. "So, to be able to have 365 days worth of data is almost unheard of until this particular technology." 

The cameras do not record the video and while it can see a vehicle's type and size, but it cannot see license plates.

The city plans to phase this technology into other new intersections.
