Other data from GLA tells us that Lewisham has the longest average journey to work (46 mins compared to a London average of 36 mins), probably because nobody works in Lewisham. We also have the highest use of rail (9%, that's 2% above any other borough except City of London - apparently).

On buses, Lewisham is the 5th highest use of buses after Hackney, Haringey, Southwark, Lambeth, and Islington. On car use Lewisham fits the London average, but Bexley and Bromley are highest users of cars for travel to work.

In terms of serious accidents on the roads the worst boroughs are Westminister, Southwark, and Lambeth (182, 157, 154 casualties per year). The next level down are Barnet, Lewisham, Camden (123, 105, 105). Five of these boroughs contain key transport corridors to central London, Lewisham doesn't.

I'm not sure that this proves too much. I think it hints that transport is not better in South East London - resulting in our long journeys to work from Lewisham and more chance of being seriously injured on the roads than most other boroughs.

My conclusion is that we don't already have better transport, nor do we have less demand, but we do have roads that are less safe. But I think I arrived at that conclusion before I looked at any stats, none of which justify a lack of investment in major road schemes in South East London.
