rolling vs full stop

Years ago, I read that a vehicle with any momentum will use 90% less fuel to get going.
Are there any studies showing how much fuel is consumed from sitting at a light vs having some momentum when it changes?
One the intersections on my commute has a slight downhill grade, and I can row the shifter between neutral and drive to barely close the gap twixt me and the vehicle in front of me until our turn to go. How slow until this is not helping?
