National transport model results, regarding traffic growth, vehicle tailpipe emissions, congestion and journey times.
Road transport forecasts 2013 presents results from the Department for Transport’s ‘National transport model’, which produces future forecasts of road traffic growth, vehicle tailpipe emissions, congestion and journey times.
‘Road transport forecasts 2013, extended version’ is an amended version of the document published on 29 July, 2013 and includes the changes of:
- an incorrect title on figure 16 (car miles per person on England’s strategic road network, whilst actually showing total traffic per person on all England roads)
- ensuring consistency between section 3.6, box 1 and figure 16, these have been amended to refer to car miles per person on all England roads
Departmental forecasts of total road traffic, road congestion, carbon dioxide, NOx, and PM10, remain unchanged.
