The Commission for a Sustainable London 2012 found that the transport system during the Games delivered an excellent service and said London 2012 should be praised for being the first Games to offer a fully comprehensive mobility service.
It also found that comprehensive public transport options and effective planning meant that the logistical operation for the Games was delivered with minimal disruption to Londoners.
It came to the conclusion that another Games success story was the food, with a wide variety of healthy, sustainably sourced, affordable meals available at most London 2012 venues, driven by the development of the London 2012 Food Vision - a first for major event catering.
