Régie Autonome des Transports Parisiens (RATP), a Paris 2024 bid partner, will invite people travelling on its public transport network to get behind the bid in a project called "All Athletes of the City".

The initiative, which runs until April 7, is striving to build momentum in the city ahead of the International Olympic Committee (IOC) Evaluation Commission visit in May by mobilising the 12 million passengers who use the RATP network daily.

RATP will also have five metro and train stations dressed in Paris 2024 colours in March.

Paris 2024 co-chair Tony Estanguet joined RATP President and chief executive Elisabeth Borne to launch the project at Saint-Lazare station in central Paris.

Also present were Pierre-Yves Bournazel, in charge of the Olympic and Paralympic project for the Ile-de-France region, and Pierre Rabadan, sport adviser to Paris Mayor Anne Hidalgo.

As part of the campaign, stationary bicycles will be set up in stations across Paris and the Ile-de-France region in the hope that passengers can get active and start pedalling and accumulating kilometres to show their commitment to bringing the 2024 Games to Paris.

"Paris 2024 wants to promote the practice of sports, to put people on the move," Estanguet said.

"As we get closer to the IOC Evaluation visit we encourage all people using the RATP network to join in 'All Athletes of the City' and get behind the campaign to bring the 2024 Olympic and Paralympic Games to France.

"Paris has one of the best public transport systems in the world, allowing ease of movement around the city and the Ile-de-France region for millions of locals and visitors every day.

"With a metro station no more than 400 metres from any location in Paris, a fleet of clean buses and other green transport solutions in the planning, our partnership with RATP underpins our ambition to host the greenest Games ever in the heart of our iconic capital city."

In February, RATP started testing its first 100 per cent electric, driverless buses on the streets of Paris, a world first in terms of public transport.

The innovative buses, which will be made available to fans, athletes and the Olympic family in 2024, will initially run along the banks of the River Seine.

"The RATP Group and its 60,000 employees are proudly committed to Paris 2024," Borne said.

"RATP brings its expertise in the field of sustainable urban mobility to Paris 2024, helping to connect athletes and visitors to the city to Paris’ iconic venues and locations via our world-class transport network.

"A key pledge of the Paris 2024 Olympic and Paralympic bid is that in 2024 every single spectator journey will be made by public transport and we are working closely with Paris 2024 to achieve this goal."

Several online petitions have been launched in a bid to hold a referendum on Paris' bid to host the 2024 Games.

This comes after Budapest Government officials withdrew the Hungarian capital's bid last month, following a similar petition that gathered 266,151 signatures.

Only Los Angeles and Paris remain in a two-horse race for the Games with the vote scheduled to take place in Peru's capital Lima on September 13.
