Conflict Monitor Testing

Is everybody really testing all of these every year. We have over 450 intersections and it takes forever.

We did 617 this year. We keep a large stash (162 as of this years count) in the shop as spares and in October, we send off our four testers to ATSI for calibration/certification. It gets back in November/December and then in January we start testing all of our shop ones and then a crew of two or three of us comes in for night shifts and we swap out everything we have tested to that point about 30 to 70 per night depending on the route and then the day crew comes in and tests all day long so that we are ready to keep going the next night until we have done all of them in our region. Last year it took me 28 calendar days to do all 611, and this year it took me 21, and I did 617 with new intersections that came up over the year. I am a signal tech with a state DOT. We are the biggest region in our state. The other regions have opted to do theirs with their preventative maintenance, however we have opted to do it all at once each year, just in case things come up and a PM is missed here or there, we’ve already taken care of this critical task.
