    I was wondering could you help me out.

    I'm doing a report for college and I was wondering does any one know the impact of being stuck in traffic has on fuel efficiency?

    IS there any charts or tables that I could compare to see what the reduction efficiency compared to free flowing traffic?

    It has a dramtic effect. Look at the urban mpg figures vs. 56km/hr.

    Look at the same figures for Hybrids (Civic IMA & Toyota Prius)

    Cars travelling in traffic at 5 mph use twice as much fuel as those travelling at 80 mph apparantly.

    In traffic and in the urban situation you do a lot of slowing down, stopping and then accelerating back up to speed. Thats that consumes fuel. Sitting at a constant speed is usually the most efficient. But theres a point where going faster is less efficient. That will vary from car to car.

    The AA must have stats.

    You could get stats on the number of cars , the average milage by an irish driver and work out the fuel economy based on that - don't forget that you'd need figures for the north too since they use up a good bit of our fuel.
