The British capital has launched an action plan to become the world's most walkable city. The 'Walking Action Plan', released by the Mayor of London Sadiq Khan's team earlier this week, aims to encourage a million additional walking trips each day by 2024. Under the new plan, streets will be designed, built and managed to encourage walking, with better signposting and maps, as well as new, wider pedestrian crossings.

"By making it easier for Londoners to leave their cars at home and walk instead, it will tackle the air pollution crisis and reduce congestion as London's population continues to grow. It will have a truly transformational impact on our city," said Will Norman, London's walking and cycling commissioner in the mayor's office.
