Politics is boring, right? So Here’s a quick tube related diversion.
Every day, I get on the Jubilee line, and I think:
“If the door system on the Jubilee line saves lives, which I bet it does, and it isn’t being retrofitted on the rest of the network somehow, which I bet it isn’t, I wonder who did the cost benefit analysis, and how they felt about it.”
Well, I don’t know about Britain, or the emotions involved, but it turns out that in Hong Kong they did retrofit such a system on the Metro, and it did save lives, and someone has done the cost benefit analysis.
“Death and injuries due to suicides and accidental falls onto the track fell by 75% across the system and the service disruptions from such incidents fell by 69.4%”
The economic report, though I’ve only been able to read the abstract, seems to suggest that installing Platform Screen doors are worth it if the savings from lower disruption levels to the tube from accidents and suicides, are added to the ‘saving’ gained from the accident reduction rates (assuming a value of three times per capita GDP for each healthy additional life year, which is a depressing datapoint in itself frankly).
Anyway, I offer this policy, free, gratis and for nothing to the next Labour mayor of London candidate.
