OAC used to calculate Transport Needs Index (TNI)
The Transport Needs Index (TNI) has been developed by Steer Davies Gleave using the Output Area Classification (OAC) to help develop transport policies and assess the social impacts of transport schemes. It is a method of quantifying the relative need for affordable public transport across the country, and via the Transport SuperSegment profiling system, providing some guidance as to the nature of the requirement and measures appropriate to satisfying it.
This following paper summarises the results of an evaluation of OAC, how the TNI was created, and the segmentation system based on it. It also uses the Cross River Tram as the basis for an example of how it can be applied to assess the social benefit of a new transport scheme.
