Traffic signal detection equipment is replaced occasionally and most frequently during maintenance activities in conjunction with a CIP project when new pavement impacts the induction loops with the pavement or at the end of a detection systems useful life (approximately 10 years). It has been best practice to replace loops in the pavement with non-invasive detection such as video detection systems, when feasible.
There are currently multiple signalized intersections that have aged intersection detection that cause frequent maintenance activity and the traffic signal system to function sub-optimally, impacting daily travel of motorists.
MS and IPL staff have coordinated on a specific type of video detection unit to be used throughout the City for equipment standardization and ease of maintenance. Staff obtained a limited source quote for 4 video detection systems to be purchased- from ITERIS by MS and installed by IPL at 4 signalized intersections to address problems with signal operations, broken loops, and frequent customer complaints.
The following locations are currently the top priority for replacement:
- 35th & Phelps Rd
- Sterling Ave & 39th St
- Sterling Ave & 35th St
- Noland Rd & Partridge/Osage Ave
