AM7 Consideration of Traffic Generated by Proposed Developments

The local planning authority will consider whether the traffic generated by proposed developments is acceptable in terms of the capacity and functions of existing and committed principal roads only, and will wholly discount any potential which local distributor and access roads may have for carrying through traffic. The local planning authority will not grant permission for developments whose traffic generation is likely to:

  1. Unacceptably increase demand along roads or through junctions which are already used to capacity, especially where such roads or junctions form part of the strategic london road network; or
  2. Prejudice the free flow of traffic or conditions of general highway or pedestrian safety; or
  3. Diminish materially the environmental benefits brought about by new or improved roads; or
  4. Infiltrate streets classed as local roads in the borough road hierarchy unless satisfactory traffic calming measures can be installed.

Traffic calming schemes should, where appropriate, include environmental improvements such as hard and soft landscaping, and should be completed before the development is first used or occupied.
