ITEM:
Authorizationto purchase four additional traffic video detection systems.
BACKGROUND:
The City of Salina has 63 traffic controlled intersections. Twenty-five of these intersections have
video detection systems or the traffi c cameras installed. It was originally proposed that the
intersections of Ohio and Cloud and Ohio and Albert be upgraded to the traffic video detection system
this year.
However, funds budgeted in the 2011 Traffic Signals and Intersection Sub-CIP for traffic signage
reflectivity upgrades will not be spent this year. The Federal Highway Administration is considering
changes in the traffic sign retro reflectivity upgr ade requirements in the Uniform Traffic Control
Devices (MUTCD). The expected changes will eliminate, extend, or otherwise revise most of the
target compliance dates for upgrading existing traffic control devices that do not meet the MUTCD
standards. Also, the changes are anticipated to be less costly for most communities to come into
compliance. Therefore the City’s upgrade program has been placed on hold until a decision has
been reached. Staff is recommending the use of a portion of funds in the Sub-CIP for the purchase
and installation of two additional traffic cameras at the intersections of Ohio and Magnolia and Ohio
and North Street.
For many years, the City of Salina has used the loop detection system to trigger the traffic lights to
change the side street lights from red to green. This system uses a low voltage current in an
underground wire that loops at the intersection behind the stop bar. The electrical current passing
through the wire detects the presence of a metal vehicle at the intersection and sends a message to
the controller to change the light.
Since 1998, the loop detection systems have bee n replaced with the vi deo detection system.
Although the traffic video dete ction system cost about $4,400 more, the system has several
advantages. The video system does not require the installation of wires in the pavement, which must
be replaced every time street maintenance, such as mill and inlay work, takes place at that location.
Maintenance can be performed wit hout blocking off the street, and the video system is more
dependable. These systems are not used for traffic enforcement.
Prior to implementing the upgrade program, a number of different types of video detection systems
where investigated and tested. Gades Sales’ Vantage Plus System with the RZ4C cameras was
selected as the best for our traffic control system and has been the sole source of traffic video
equipment. The Vantage Plus System has proven to be dependable and the quality service provided
by Gades Sales to repair or to provide replacement parts has been excellent.
Gades Sales quoted $17,500 for equipment and installation per intersection. The equipment includes
four cameras, a control unit, mounting brackets, and wires. Delivery would be within 45 days. Staff
believes this to be a fair and reasonable price.

FISCAL NOTE:
Sufficient funds have been budgeted in the 2011 Sub-CIP Traffic Signals / Intersections to cover this
expense. Of the $70,000 required to equip four intersections with traffic cameras, $35,000 will come
from the previously budgeted funds for traffic cameras and the other $35,000 will come from
budgeted funds ($51,000) for traffic sign retro reflectivity upgrade, which will not be spent this year.
CONFORMANCE WITH STRATEGIC PLAN:
Goal 3: The City will provide the highest quality of services, consistent with governing body direction,
available resources and staff commitment to quality.
RECOMMENDED ACTION:
Staff recommends the City Commission approve the purchase of two traffic video detection systems
from Gades Sales Company, Inc. in the amount of $70,000.
