A few days ago (29th June) I blogged Rodcorp's idea of a map illustrating which tube lines got the most passenger traffic. His map wasn't based on any real data, but thanks to Stephen Knight, we've found out that a map like this was produced for Sheriff Ken's Transport Strategy in 2001. The whole document is a lightweight 458 pages, but Chapter 4C focusses on the London Underground and we find three maps. The first shows underground crowding in the morning from 2001
The report says: "Overcrowding is now experienced across the Underground network, particularly at peak times, and most noticeably on sections of the Central, Piccadilly, Victoria and Northern Lines. Large parts of the network carry more passengers than the �planning standard� (broadly a maximum of one person standing for each sitting across the whole peak hour) allows � in some cases more than 25 per cent above"
The next map projects what the crowding would be like in 2011 without Ken's Transport strategy. Notice how the black lines have increased and thickened.
The final map predicts the system with hardly any nasty black bold lines after Ken's proposals have been introduced:
"To address overcrowding, there is an urgent need to expand capacity. In the first instance, this will be achieved by the rehabilitation and modernisation of the existing system. In the longer term, this requires a substantial programme of investment in new lines and hence additional capacity. Major new rail proposals are discussed in more detail in chapter 4Q � expanding London�s transport system: major projects."
