SINCE the start of the Olympics, Ndieme Lame has been commuting every day to the Stade de France where she works as a volunteer helping visitors find their way. The 57-year-old wheelchair-user is in awe at how easy it’s been to cross the city on public transit to reach the Olympic stadium.

“I never would have believed I could make it here almost on my own,” she said Wednesday after her one-and-a-half hour commute from her home in southern Paris.

Her daily journey highlights the city’s efforts to improve accessibility for people with disabilities ahead of the Olympics and Paralympics. Lame said an online system that lets her book assistance at commuter train stations has been particularly helpful.
