The Department for Transport has made no specific analysis of this effect on the London borough of Bexley. Before the launch of Oyster Pay As You Go, some high level analysis was carried out on the likely effects of Pay As You Go fares changes across London as a whole. Within that analysis there were both positive and negative effects, but overwhelmingly those who had been disadvantaged can switch to Pay As You Go and get the best value fares available for their time of travel.
