And the Olympics are set to cause chaos(混乱) on the roads too with the creation of special‘games lanes’ likely to bring many main routes to gridlock. The controversial lanes will be reserved purely for the use of competitors and VIPs.Even buses and taxis will be barred(禁止) from using them.①Around 5.3 million people are expected to turn up for the 16 days of the London Olympics．August 3 is expected to be the busiest day with around 800，000 people using public transport. Organizers fear a repetition of the 1996 Atlanta Olympics which became known as the ‘Glitch(差错，缺点) Games’ after transport chaos caused many competitors to miss their events.
