Lessons from the London Olympics could help Rio "cope with the pressure of additional visitors, deliver athletes to events swiftly and allow residents to get to work" according to the letter.

The 'London 2012 and the Transport Legacy' report published by the Assembly's Transport Committee suggested that extensive testing of the transport network, willingness from commuters to adapt their travel plans and major investment were key factors in London coping with the huge influx of visitors.

A tota of 60 million visitors used the Tube during London 2012- a 30 per cent increase on regular figures- as the number of passengers doubled on the Dockland Light Railway (DLR) and rose by 47 per cent on the London Overground.

The report also identifies ways in which London can learn from the experience of hosting the Olympic and Paralympic Games.

London have offered advice to Rio 2016 on how to ensure that the city can cope with the influx of visitors during the Games

It targets six specific areas including ensuring the long-term improvements for the Tube system and encouraging changes in the way in which Londoners travel, promoting cycling and walking.

Caroline Pidgeon chair of the Transport Committee, said: "Major transport investment, good passenger information and operator collaboration all led to an effective, smooth-running transport network during summer 2012 – part of the package that made London 2012 such a success.

"Rio faces new - and different - challenges in the run up to the Games in 2016, but London's experiences can bring lessons to the table that are relevant to all cities planning to host the Olympics, World Cup or other major sporting events.

"We must now make sure the £7.2 billion ($10.8 billion/€8.3 billion) invested in transport allows London to gain its own Olympic legacy.

"Smooth-running, reliable public transport, better passenger information and accessibility for all, must be the  daily norm for passengers.

Pidgeon also spoke of the legacy of the transport infrastructure for the Games, and how it would improve public transport in London in the long run.

"Moving forward, lessons learnt could also potentially lead to the Tube running later at night and better transport co-ordination for future events held in the capital.

"The high-performing transport system of London 2012 must become an everyday experience for Londoners and not just an exceptional, one-off achievement only beneficial over the Olympic summer."
