Part 1 sets the 2015 vision for London and explains what TfL aims to achieve through its delivery. In this section, we address the issue of what is actually meant by 'a walking friendly city'. Part 2 highlights why we should be encouraging more walking and the potential benefits for health, the environment, the community and the economy. It also looks at the factors that have led to a decline in walking over the past decade. Survey data shows the issues that people rate as significant deterrents to making journeys on foot, illustrating the broad range of organisations and policies that have an impact on the walking environment. Part 3 sets out London-wide targets, suggests an approach to developing targets at a local level and identifies actions needed to improve conditions for pedestrians and encourage people to walk more.
