SUBJECT: HALL JOHNSON CORRIDOR TRAFFIC SIGNAL TIMING
COORDINATION PLAN & SIGNAL DESIGN CONTRACT
City Council to consider approving an Engineering Services Contract with Kimley Horn
Engineering in an amount of $33,000.00, for Traffic Engineering Services:
to design a new traffic signal at the intersection of Hall Johnson Road and
Countryside Drive, and
prepare signal timing plans for the five traffic signals in the Hall Johnson Road
corridor from Pool Road to SH 121, including the new signal at Countryside Drive,
authorize staff to execute said contract and take any necessary action.
FUNDING SOURCE:
Funds have been programmed in an amount of $150,000 from 2000 GO Bonds, Account#
178-78101-011 and 2003 GO Bonds, Account #178-78125-015 for engineering services
and construction.
BACKGROUND:
With the new Master Traffic Controller and the new signal controllers being deployed to
signals within the City, we now have the capability to implement traffic coordination timing
plans for the traffic signals in the Hall Johnson Road corridor that should improve the traffic
flow. The new Master Traffic Controller provides direct communication between the master
unit and each new traffic signal controller as we deploy them in the field this year.
This direct communication enables us to implement time based coordination between the
signals to address predominant flow patterns during the day including the AM and PM
peaks, mid-day and weekends.
Time based coordination between signals is dependent upon each traffic signal's clock
maintaining synchronization with neighboring signals. Typically, individual clocks in the
signal controllers tend to drift over time. With our new system, the Master Controller resets
the time with all of the individual controllers on a daily basis at midnight so the impact of
drift is greatly reduced.

The intersection of Countryside Drive and Hall Johnson Road meets traffic signal warrants
in two areas, four hour vehicular volume and peak hour vehicular volume.
Staff recommends approval.
