The Department conducted a thorough traffic study of I-285 before deciding to increase the speed limit and implement VSL. Georgia DOT believes I-285 can safely accommodate the increased speed. Experience to-date on the southern section of I-285 supports decision to increase base speed limit on Top End.
Why Implement VSL on Top End?
I-285 Top End carries an average of 50,000 more vehicles (100,000 more in some corridors) than SouthSide I-285 and also has almost twice as many interchanges, there is more traffic, more merging, more weaving, more congestion and a greater risk of crashes.
