By 2030, congestion is projected to cost London GBP 9.3 billion a year. To counter this, the city is rolling out an extensive transport plan, which includes a dedicated walking action plan aimed at adding 1 million additional walking trips a day. The city will invest GBP 2.2 billion to redesign streets, install better signposting and maps, add more pedestrian crossings, as well as improve public transport. Analysis shows that a walkable London is significantly more land-use efficient, can save up to GBP 1.6 billion in public healthcare costs, increase retail sales, reduce emissions, and increase social cohesion and living conditions.
