CS9: Management of Roads
All new development will be directed to the appropriate category of road in the road hierarchy based on its scale, traffic generation, safety impact, and environmental effect.
The traffic generated from new development must be compatible with the location, design and capacity of the current and future operation of the road hierarchy, taking into account any planned improvements and cumulative effects of incremental developments.
Improvements to the network and all traffic management measures will be designed to channel long distance through traffic onto the motorway and primary roads (i.e. M1, M25, A5 and A41).
In Hemel Hempstead road improvements will focus on relieving congestion in and around the Maylands Business Park, including the delivery of a new north-eastern relief route, and improving the capacity and safety of the Plough Roundabout. Elsewhere, small-scale improvements will be undertaken to tackle local environmental and safety problems.
Other new road capacity will only be justified for local environmental, air quality (including any declared Air Quality Management Areas), safety reasons, or for accommodating local access requirements.
Local road space will be shared and designed to allow the safe movement of all users.
In villages and the countryside, special regard will be paid to the effect of new development and traffic on the safety and environmental character of country lanes.
