The Guardian reports on research that looked at three London boroughs to value overall health benefits of active travel over 20 years at up to £4,800 per head.

Policies to help people walk and cycle such as low-traffic neighbourhoods can create public health benefits as much as 100 times greater than the cost of the schemes, a long-term study of active travel measures has concluded.

The research, based on six years of surveys among thousands of people living in three outer London boroughs that introduced LTNs or similar schemes, found they tended to prompt people to switch some trips from cars to active travel, although the effects were varied.

The cumulative public health benefit of people being more active was estimated at as much as £4,800 per local adult over a 20-year period, the authors found, as against a cost per person to build LTNs of about £28-£35, or £112, depending on the type of scheme built.

Significantly, the study found that the positive impacts, particularly for walking and cycling rates, tended to be more noticeable after schemes had been in place for a year or two, rather than immediately, indicating that councils should not determine an LTN’s success or otherwise too early.
