Fuel Economy in traffic

[bobski1]

Recently changed work locations and my commute not has me sitting in quite a bit of traffic. Wondering if people also see a horrendous drop in fuel economy/miles remaining when in traffic or if there was a technique/method to inch the car along. I've tried just lifting off the brake and allowing it to roll forward slowly and also gently pressing the accelerator and neither seems to be any better than the other.

It did for about a month do really well but I think it meant not actually fully lifting on the brake but not sure if that is any good long term for the discs/pads.
