Why Maintain Traffic Signals?
To preserve the benefits that the original installation provided
To give motorists a consistent driving environment
To avoid liability claims Extend life of installation and
reduce life cycle costs

Unpredictable, As-Needed Work Diagnose and Repair
Unexpected flashing operationCommunications failuresPole knockdownsBurned out lampsWire theft

Asset Management Relatively New National Guideline Input and Response Tracking
Good general conceptWhat types of calls are consuming
staff timeFeedback to design standards
Inventory TrackingBuild a database
Keep track of parts or suppliers that are most reliable
Feedback to technical specificationsSource ITE/IMSA

Typical Current Practice
Basis for statements:Republic ITS/Siemens provides
contract maintenance to over 200 public agencies in CA and 300 nationally
Most of our clients have under 100,000 population
Many of our clients do not have dedicated traffic engineering staff
![Page 9: Traffic Signal Maintenance – Best Practices Presented to: ITE Western District Annual Meeting Santa Barbara June 25, 2012 With: Mike Kato Beza Kedida Cedric](https://reader038.vdocument.in/reader038/viewer/2022102722/5518a025550346881f8b4834/html5/thumbnails/9.jpg)
Typical Exclusions Preventative Maintenance
Keep inventory of part installation dates or manufacturing source
Signal timing in officeTrim vegetationCheck conductor condition‘Meg’ or reseal loops wiresAnnual load test of BBS batteriesCompare timing settings to current
recommendations Any kind of Asset Management

Why are there exclusions?
Cost No traffic engineering staff so
what would they do with the asset data anyway?
Reliance on judgment of maintenance crews

“New Tech” Equipment
Traffic signal equipment has evolved considerably in the last 10-20 yearsLED signal headsVideo detection systemsFiber optic or wireless interconnectBattery backup systemsComponents with Ethernet
connections
![Page 12: Traffic Signal Maintenance – Best Practices Presented to: ITE Western District Annual Meeting Santa Barbara June 25, 2012 With: Mike Kato Beza Kedida Cedric](https://reader038.vdocument.in/reader038/viewer/2022102722/5518a025550346881f8b4834/html5/thumbnails/12.jpg)
“New Tech” Recommendations
LED Signal HeadsRe-lamp every 5-10 years
Video Detection Systems (VIDS)Annually test aiming and accuracy
of detection zone shapes Fiber Optic Interconnect
Monthly vacuum dust off components

“New Tech” Recommendations
Wireless InterconnectAnnually check comm error reports
Battery Backup SystemsAnnually perform battery load tests
Modern equipment with Ethernet portsBuy diagnosis software and
connection cables
