Variable Speed Limits Implementation and Speed Limit Increase I285 Top End Perimeter Georgia DOT continues to look for cost-effective, innovative ways to address traffic in the metro Atlanta region. One of the most congested roads in metro Atlanta is the northern half (called the “Top End”) of I-285. The “Top End” is the 36 miles on I-285 within Fulton, Cobb and DeKalb counties, north of the I-20 interchanges. To help relieve congestion and improve safety on that corridor, the Department will implement Variable Speed Limits (VSL) on the Top End of I-285 beginning September 2014. What is VSL? Variable Speed Limits are limits that change based on road, traffic and weather conditions. VSL electronic signs slow down traffic ahead of congestion or bad weather to smooth out flow, diminish stop-and-go conditions and reduce crashes. Overhead changeable message signs will warn motorist of upcoming congestion, giving them ample time to slow down. More consistent speeds improve safety by helping to prevent rear end and lane changing collisions due to sudden stops. The speed limit will increase from 55mph to 65 mph. This new limit will be more consistent with a similar increase implemented on Southside I 285 last fall. Additionally, the new limit is more consistent with driver expectations and behavior on I285. Schedule Through July: instillation of overhead changeable message signas and electronic VSL signs on shoulder August: Testing End of September: Roll out
