TOKYO, Japan (AFP) — Less than a year before the opening of the Tokyo 2020 Olympics, organizers tested shuttling thousands of athletes around the megacity in a bid to gauge the effect of the Games on traffic.

Over 11,000 athletes are due to participate the Summer Games next year, and almost all of are due to attend the opening ceremony on 24 July.

With the athletes village some 20 kilometers from the opening ceremony venue, officials estimate it will take around 40 minutes by bus — even if the current transport plan works.

“Balancing vibrant urban activities and management of the Games is an important subject for us,” said Katsuhisa Saito, senior official in charge of the Tokyo 2020’s transport strategy.

On Sunday the journey took about 10 minutes less than expected with no conspicuous traffic jams.

“The overall result looks good,” Saito said.

Some roads surrounding the two venues were closed off to regular vehicles with exception of residents while a partial ban on accessing the expressways was also introduced to avert congestion.
