They will then prepare a signal timing phasing and progression plan based on the current traffic volumes, and will implement this programming and verify performance with a "before and after" analysis to quantify the cost-benefit analysis for the new timings.
Kimley Horn was the only responsive response we received. Other firms we have contacted to request proposals from cited lack of resources available to perform the exercise or a conflict of interest because of existing commitments with Georgia DOT as part of the SigOps program.

SigOps is performing the software conversion for 22 of the signals in the city from TACTICS to MaxView/MaxTime at no cost to the City.
