In Alpharetta, Windward Parkway at Ga. 400 was the most active intersection in terms of accidents with a total of 62 in 2012, which is the most recent year for the city’s traffic data.
That year there were 52 accidents at Windward Parkway and Westside Parkway, 51 at Mansell Road and Westside Parkway, 49 at North Point Parkway and Old Milton Parkway and 40 at Windward Parkway and Ga. 9.
“When we analyze the data from 2012, we find that 78 percent of traffic accidents at our top locations for crashes were read-end collisions and that the cause of 73 percent of collisions at those locations was a driver following too closely,” said James Drinkard, Alpharetta’s assistant city administrator. “Interestingly, 65 percent of the collisions at those locations occurred during clear weather. The conclusion then is that too many drivers are being too aggressive and/or are in too big a hurry on area roads.”
Roswell’s intersections with the highest crash rates in 2012 — the most recent year for data — were Ga. 9 at Riverside Road/Azalea Drive with 60 accidents, Ga. 9 at Holcomb Bridge Road with 100 accidents and Ga. 92 at Hardscrabble Road with 76 accidents.
More than half the crashes were rear-end collisions, said Muhammad Rauf, city traffic engineer.
In Milton, the top three intersections by accidents in 2013 were Ga. 9 at Bethany Bend with 24 accidents, Birmingham Highway at Providence Road with 17 accidents and Arnold Mill Road at New Providence Road with 12 accidents.
Following too close was the leading factor contributing to crashes, said Jason Wright, the city’s communications manager.
All three cities and the state department of transportation have improvement projects at these intersections that are in planning, in construction or recently completed.
“The effects of those improvements will not be evident until the 2014 data is available and analyzed, but the primary thing that will reduce collisions at these locations is altering driver behavior — slow down and increase distance between vehicles,” Drinkard said.
