Scope and Detail of Transport Assessment
The Transport Assessment should be scaled to the development's size and transport implications, and may require a travel plan for significant traffic-generating uses.
The coverage and detail of a TA should reflect the scale of development and the extent of the transport implications of the proposal. In applications for significant traffic generating uses, a TA may need to be accompanied by a travel plan. The Draft guidelines to Transport Assessment in Northern Ireland (2004) issued jointly by DRD and DOE provides detailed information on this process and should be referred to directly.
