RRFN light functioning normally.
Problem is with RRFB light.

To person who called the Engineering Department regarding this issue:

We are sorry we were unable to call you back as you did not leave a number. Hopefully you may see this response here.

We did contact Transportation Traffic and Parking directly first, and spoke to one of their traffic engineers. They directed us to add a seeclickfix ticket after speaking with them.

We apologize for using the acronym RRFB (rectangular rapid flashing beacon), as it is a relatively common one in the traffic world and we work with them often.

We are acutely aware that SeeClickFix is not the venue for safety emergencies, and even though this issue was not an immediate safety hazard we did contact Transportation Traffic and Parking directly.

Thank you for keeping an eye out for potential safety issues on SeeClickFix, and if you have any further questions please feel free to call back and we will be happy to discuss them with you.

Thank you for your response.

Good Afternoon, I am with TT&P. We are aware of the sporadic operation of the Rectangular Rapid Flashing Beacons (RRFB) on Clinton. It seems that the radio signals between the signs is where the problem lies. It is my intention to schedule our crew out there during the week of 26 March to troubleshoot. Thank you for your patience. I will update as we progress with the troubleshooting. Scott Westervelt - Traffic Signal Superintendent

While you are there please check out the light on Clinton and Lombard because the green light on Clinton changes after about 10 seconds,

Good Morning, I have visited this location and also reviewed the database for its operation and found that it is operating within the correct parameters. This intersection is part of a coordinated system and the timings for the corridor are being reviewed. I will take a look again while we are out for the RRFBs.

Thank you for your post. We are currently investigating this concern.

Repaired under separate work order.

Thanks for fixing this request!
