The ramp meters are part of an extensive GDOT project to create smoother traffic flow on I-285 by managing traffic entering the system. Because traffic on an on-ramp tends to arrive in large groups of vehicles, it creates shockwaves in traffic flow during congested periods on the highway from many vehicles attempting to merge in a short period of time. The ramp meters cause the merging vehicles to spread out arrivals over a longer period of time, which ultimately reduces stop-start conditions. Basically, you spend a little more time on the on-ramp so that you can spend less total time on I-285.

We will forward your comment to the team of engineers employed by GDOT to manage the system to make sure that this particular signal is operating properly.

Thank you for taking the time to bring this to our attention, and thank you for using SeeClickFix!

I'm not really seeing how this helps. The problem, inherent with the cloverleaf exit from 285E to PIB north is that every vehicle larger than an SUV takes the cloverleaf turn really slowly, backing up everyone behind them and bringing everyone to a stop or crawl. Not sure how to fix this (except for an expensive ramp type of exit).

Work has been completed in coordination with this issue. Thank you for using SeeClickFix!
