Subject

Approval to Purchase a Spare Traffic Signal Control Cabinet with Controller and MMU.

Background

Staff seeks City Commission approval to purchase a spare traffic signal control cabinet which will include a signal controller and MMU (Malfunction Management Unit) installed within this spare cabinet. The City maintains 49 signalized intersections with additional signals planned along Franklin Road. With the increased concern regarding traffic management throughout the middle Tennessee region, we believe it is critical to gain the redundancy of a spare cabinet. The control cabinet works as the heart and brain of the signal and in the unfortunate event of a traffic accident or catastrophe where a cabinet is damaged, the cabinet could be swapped out with operation restored in about four hours. The alternative would require an emergency acquisition of equipment and services to make the signal functional again. In some instances, other area agencies have gone as long as one week treating a signalized intersection as a four-way stop until parts could be obtained and repairs made.

On May 29, 2019, staff opened sealed bids for various equipment purchases related to the Traffic Division of Public Works. Two equipment vendors bid on the traffic signal cabinet with controller and MMU included and the two bids were within $95 of each other. However, the less expensive bid for equipment from OB Traffic in Houston, Texas was deemed unresponsive as the bid did not meet the required specifications for the controller. An Econolite controller was specified as that is what the City uses system-wide. OB Traffic quoted a Peek controller which is incompatible with our software.

Therefore, staff is seeking approval to purchase the traffic signal control cabinet along with the controller and MMU for $14,895.00 from Southern Lighting & Traffic Systems in Cumming, Georgia. It is staff's opinion the price quoted is fair and reasonable.

Please direct any questions to the Public Works Director.
