The CS9 proposal in its current form does nothing to pro-actively design or resolve walking issues and thereby does nothing to promote healthy activity on the footpath, a direct contradiction to the Healthy Streets directive.
A study from the International Journal of Hygiene and International Health proves walking is an extremely healthy life choice.
In fact, many think walking is healthier than cycling for cardiovascular health. Anyone with a Fitbit or other activity tracker will tell you more calories are burned walking vs cycling.
Regardless of what you may believe, reduction of pavement width is not urban design. It is a consequence of installing one amenity at the expense of another. And with pavements reduced, less people will walk and less will socialise per the evidence found in the study above.
This does not a community make.
