City Currents articles are prepared by
the city of Dunwoody and published
each month by the Dunwoody
Reporter as a community service.
They are intended to offer insight
into the workings of Dunwoody city
government. This installment focuses on the city's Public Works Department.

Infrastructure insights - congestion relief
From the beginning of Dunwoody’s
incorporation more than four years ago,
the city’s roads, traffic signals and inter
sections have remained top concerns for
the community.
Over the last six months the city’s
public works department has been in
volved in a number of important initia
tives to improve traffic flow throughout
the area. The maintenance and upkeep
of these roads, signals and sidewalks is
essential in addressing traffic congestion
relief as well as for the safety and quali
ty of life of those who live, work or pass
through the city of Dunwoody.
Most recently, the city has been hard
at work examining traffic flow and opti
mization of the city’s 57 traffic signals.
To get the ball (or cars) moving forward,
the city, along with the Perimeter CID
and adjacent local governments, helped
create the Perimeter Traffic Operations
Program (PTOP) which
provides active manage
ment of 26 Dunwoody
signals in the Perimeter
business district.
In less than a year, the
program has had a real ef
fect on safety and signal
timing improvements at
multiple intersections. For example, the
program has improved the percentage of
functioning vehicle detection devices at
signals from 84 percent at the start of
the program to 95 percent today. That
translates to more efficient cycling of the
traffic signal and less driver frustration.
In addition to improvements in the
Perimeter area, Dunwoody also recent
ly received assistance from another state
signal timing program to retime sig
nals on Mount Vernon Road, Cham-
blee Dunwoody Road, North Peachtree
Road and Tilly Mill Road.
Travel times and traffic delay were
measured prior to and after the new
timing was implemented and notable
improvements were realized. Primarily,
there’s been an overall reduction in trav
el time and delay at intersections. We’ve

been able to deliver a 30 percent reduc
tions in mid-day travel time on North
Shallowford, Chamblee Dunwoody and
North Peachtree roads; a 30 percent re
duction in evening rush-hour travel
time on North Shallowford Road, re
sulting in reduction of
more than 1 minute in
travel time on the cor
ridor; a 10 percent re
duction in travel time
for morning and after
noon rush-hour traf
fic on Chamblee Dun
woody Road; and a 20
percent decrease in travel time on Tilly
Mill Road throughout the day.
These results demonstrate the success
of the retiming efforts in providing sig
nificant improvements at very little cost
to the city.
The city is also hard at work to best
address common roadway and infra
structure improvements. This is where
residents can help the city efficiently
identify and resolve issues.
We ask residents for help in identi
fying and reporting potholes or traffic
safety issues through our automated on
line web application and reporting sys
tem: SeeClickFix.com. These free tools
are also available in a mobile applica
