Urbanism and road design

Public spaces often include traffic.

The National Design Guide draws attention to the wide range of topologies and street types appropriate to suburban and town centre, etc. locations.

Increasing the kerb radius from 1 metre to 6 metres with 15 metre visibility splays widens the space between buildings from 6 metres to 16 and creates the characteristics of a suburb.

The human scale of many city, town and village centre roads relies upon tight kerb radii of 300mm (left) or less than one metre (right). Applying a Design Manual for Roads and Bridges (BMRB) six metre radius and 15 metre sight lines effectively precludes development of this scale.
