In my personal opinion, better that than trawling slowly through traffic jams. If their train system is over capacity, more people moving through cars would be even more of a nightmare. The feeling of independence (or not feeling like “cattle“) is substantially reduced in big cities, where you are subjected to a lot of traffic rules, overcrowding of cars, jaywalkers, accidents, potholes, diversions, expensive parking space... I could go on.

> In my personal opinion, better that than trawling slowly through traffic jams. I think the best way to describe it is that it sucks either way to commute in Tokyo no matter what means of transports you end up using, except if you can live very close to your office, which is not the experience of 99% of people.

  It sucks less on a nice heated/cooled chair, with fresh air and nice music and no ------- one around - even in a 10 times less populated city

  As mentioned in my previous comment, it really does sound like you don't know what you're talking about. Commuting in Tokyo is not without problem, but consistently better than commuting anywhere else I've been. Also, you seem to completely ignore the point that the alternative "everyone commutes by car" (or you have other alternatives?) would result in a constant gridlock given Tokyo's scale - so it would be orders of magnitude worse.

I've always wondered why they don't do 'assigned seating' in a metro train. It is feasible to know everyone's destination station at the time of boarding. And it is feasible to know current occupancy of each car in the train. So potentially, people can be assigned to a specific car (need not be a specific seat), such that crowding in each car can be capped and more cars per train can be added without having to increase the platform length. Also, even when platform length isn't a constraint, I have seen metros running with less cars and preferring to keep it crowded. Why is that?

I challenge you to find a mechanism that works for this and is quick enough to keep up at rush hour in the average Tokyo train station. Additionally, people move at different speeds through the station due to factors like age, familiarity with the network, disability, bladder capacity etc. It’s a non-trivial problem to solve, and likely only marginally improves user experience.

    Put an electronic sign up on each station platform indicating where the cars with most space will be on the next train. Some people will rush to those cars, some will just stay where they were. By varying the amount of notice given or the threshold where you consider a car "less full", you can distribute the travellers more evenly. I suspect the reason this isn't valuable is that the feedback loop is already pretty good at high occupancy rates: when one car is at capacity, every other car is too.

    You can indicate your destination at the entry turnstile to the platform and it will tell you two things: (a) the car you should board, and (b) the car you should exit from at the destination station. Most times, (a) and (b) are same. Some times, (a) and (b) can be different – say when you have more cars than then length of the platform supports, then some cars will hang off the platform length and hence their doors won't open. If you were assigned to board such a car, you have to make way to another nearby assigned car whose door can open, which is assigned to you so that everyone won't crowd the same last car aligned to the platform.

  Have you never been in a metro train before? There's not actually that much seating, if you only had people sitting down that'd be like a tenth of the train's capacity. Not to mention the trains stop every minute or two, and people don't, like, book that stuff ahead of time.
