Agreed but it appears to be a closely guarded secret.
It's not really, Alot of efficient driving is common sense. You have already outlined a few things yourself.
Anticipating the situation ahead and in good time to prevent yourself having to come to a halt at traffic lights saves alot of fuel and wear and tear on the vehicle. Most fuel around town is used getting the vehicle from a standing start to driving speed.
If you ever watch cars approaching traffic lights it is amazing how many people accelerate all the way upto the red light instead of just letting the vehicle roll up to it.
Again, on the approach if you were going a little slower it might be green by the time you get there saving you from stopping at all. I have a saying for traffic lights "Be prepared to stop and ready to go"
