There is no ordinance that mandates the length of a yellow light and that length is determined by traffic engineers, not police officers.
I never stated that yellow light intervals were determined by police officers, that was your inference.
However, I would be somewhat shocked if any effort to either reduce yellow light intervals for the purpose of increasing citations, modify red-light intervals or synchronizing lights for better traffic flow was done without consultation with the department that ultimately has to deal with the outcome (being the PD).
Consider yourself shocked!
Tulsa has traffic engineers who go to school for years and years to be trained in traffic engineering issues and traffic flow. I'm confident Tulsa follows federal ANSI guidelines for signage, speed limits, road markings, ......... I'm also confident yellow and red lights are part of those standards.
As for synchronizing traffic signals, that is a luxury Tulsa would love to have, but is also extremely expensive. It requires all of the signals be able to talk with each other, which they currently can not do. Except for downtown, and a few intersections where traffic signals are close to each other, say on either side of I-44, and the one experimental synching happening on 71st Street around Memorial (paid for with a grant?), no other lights are currently synched, nor do they have the ability to without upgrades.
