Although the "fine print" says "
Updated Jan 10, 2019; Posted Dec 02, 2014", I can't see that anything new has been added in the last 5 years.
Updates from my listed article:
"The Institute of Transportation Engineers (ITE), which makes the traffic control policies for the United States and other countries, notified Järlström that he’s right: drivers often get caught in a no man’s land when trying to make a turn and they end up running red lights."
The following is pretty funny:
"Järlström forged ahead and got a big victory several years ago when Professor Alexei Maradudin — one of the engineers who wrote the original formula used to determine the duration of yellow lights — told ITE his 1959 equation was never meant to regulate vehicles making turns."
So, it took someone
born in Sweden, now living half way around the world, to fix a 60 year old engineering problem.

ps. Professor Alexei Maradudin was born on Dec 11, 1931, and would have been about 28, when this "yellow light" formula, was formulated.
He's currently @ University of California, Irvine
Research Professor, Physics & Astronomy
