A series of trials conducted in London boroughs that will be affected by the games has highlighted measures suppliers to shops, pubs and hotels, for example, can take to minimise noise from deliveries.

The draft code was developed in partnership with the Freight Transport Association (FTA) and Noise Abatement Society (NAS).

Advice includes making sure all equipment is maintained to be as quiet as possible, ensuring all staff and drivers are aware of the code and trying to avoid more than one vehicle turning up at the same time.

Drivers should know the appropriate access point, avoid sounding their horn, avoid waiting outside residential properties, switch off engines when not manoeuvring but minimise start ups and over revving. Care should also be taken to switch off radios, avoid metal on metal contact and to use sidelights when off road and safe to do so.

TfL is asking for feedback on the code, which is available at www.tfl.gov.uk/2012outofhoursdeliveries, from the freight industry, the boroughs and other interested parties before publishing a final version in the new year.

Peter Hendy, London’s transport commissioner, said companies need to be well prepared to cope with busier roads at peak times and restrictions on some routes.

He said many firms intend to stock up on non-perishable goods ahead of the games and to share delivery vehicles with neighbouring businesses but stressed that revising delivery times is also viable.

TfL said deliveries and collections make up 17% of all London traffic – rising to 25% in central London, with 281,000 freight journeys made in the capital from Monday to Friday each week.

The boroughs involved in the first round of trials were the Royal Borough of Kensington and Chelsea, Southwark, Redbridge and Westminster City Council. Five more trials will take place in the new year.
