Figures are based on information known to date. Jobs and homes are based on economic modelling techniques which attribute a proportion of the growth potential of the land released e.g. the land released by the Postwick Hub Junction can accommodate around 5,000 jobs and 600 homes. BCRs are calculated using the average cost of recent HA schemes and include both traffic flow and accident benefits data. While every effort has been to make information consistent along the route, evidence has been sourced from several different studies so some methodological inconsistencies may exist.
