HS2 and economic output
In a report commissioned by the Department for Transport in 2013, KPMG estimated that HS2 would create £15 billion annually in increased economic output, with phase one accounting for 40 per cent of that benefit (£6 billion per annum).
However, a ‘new mathematical model of human interactions’ predicts that HS2 phase one would create only £3.6 billion annually in increased economic output; less than one per cent of the current output of Birmingham and London.

[…] Dr [Aaron] Sim carried out the study with Professor Michael Stumpf, also from the Department of Life Sciences, Professor Mauricio Barahona, from the Department of Mathematics, and Professor Sophia Yaliraki, from the Department of Chemistry at Imperial.
They say the findings should be used to help politicians and civic planers to put in place the most efficient, widely beneficial and fairest infrastructure.
