This analysis ignores people who use only the train and tube or just the tube. If you hinder the tube to try and improve traffic what will happen is traffic will eventually increase where you have made improvements (the bottlenecks referred to in the article) and the tube service has still been degraded.
The failure of the analysis is to assume that car drivers should be a consideration (perhaps that is due to the US bias toward car travel over public transport). Really we need to be improving public transport such as the tube so much that car driving is disincentivising as much as possible and public transport is incentivised as much as possible.
