In the interests of road safety and to reduce environmental impacts, commercial and employment developments that generate larger goods vehicles should be segregated from residential areas. Layouts should be designed so that commercial and employment traffic does not need to use residential roads.
To support sustainability, the council may accept mixed-use developments that include small commercial premises that generate limited goods vehicles, such as offices or a shop, particularly in or close to town centres.
The materials and construction methods used for a road must be based on the largest vehicle expected to use it.
