Title
Staff Report for Resolution Establishing Standard Components for the City’s Traffic Signal System to Ensure Compatibility
Staffreport
RECOMMENDATIONS
Staff recommends that the City Council adopt a resolution standardizing the components to ensure compatibility with the City’s existing traffic signal system.
BACKGROUND
During the Pre-Bid meeting on December 13, 2011 for the Bancroft Avenue and 136th Avenue Signal project, the issue of which components could be used for the project was raised. Staff investigated the issue and determined that the City’s traffic signal system requires that certain components be used to ensure compatibility and functionality. Standardizing the components will ensure compatibility, functionality, and will reduce costs.
Analysis
The City’s new Advanced Traffic Management System (ATMS) was completed in spring 2011. To allow the traffic signal system to function at its full potential, we must ensure the compatibility and performance of its major components. Staff recommends that the following components be established as the City’s standard traffic signal system devices:
• Naztec Traffic Controller
• Naztec Controller Cabinet Assemblies
• EtherWan Ethernet Switch
• COYOTE Dome Closure
• Aldis Video Detection System
• Econolite Video Detection System
• Polara Navigator Accessible Pedestrian System (APS)
• 3M Opticom Emergency Vehicle Preemption (EVP)
The above listed items were initially selected by competitive bid or on a performance basis. These items are either integral components or accessory components compatible with the existing equipment. Economy and efficiency support selecting these components through a competitively awarded contract. In addition, standardizing these traffic signal system components will allow the City and/or contractors to purchase these components directly from vendors when it is advantageous to the City. It will also reduce routine maintenance expenses, avoid extra training on new components, and decrease the inventory of replacement parts.
