Thanks for that, all

how will they reduce braking dust? I thought they were primarily only going to use the brake power for energy.

About half of pollutants come from brakes and tyres - http://publications.jrc.ec.europa.eu/repository/bitstream/JR...

Bringing in electric buses will not decrease these pollutants. They will also not remove enough of the other half of the pollutants. The change needs to be far wider and harsher.

VSTS + Slack

Of course it will affect them - they will have to ensure their drivers are fit to drive at all times. Drivers will not be able to work extended periods of times and Uber may be forced through this to pay for holidays + sick leave.

What problems you will be solving

What tech stack you use

1. Not necessarily - 4 short people behind 4 tall people will do the job. But I would argue London platforms ARE overcrowded already, rather often. Mostly because you can only control where people go a certain amount. If everyone gets off many trains at the same stop, but don't leave, there isn't much TfL can do short of asking people to leave for their own safety. Maybe if TfL actually got any decent amount of funding (Like Southern and SouthEastern got due to being rubbish) from the government, they could work on creating further lines and spaces that would decrease Underground congestion. Instead, the government has cut funds and the Mayor has frozen fares. And yet people still want infrastructure to improve.

2. 1 Person != 1 Wifi, but if 1W = 0.2P, you can still get a good estimate.

3. TfL is a large bargaining chip for the mayor - no mayor would even consider risking a PR disaster like the one that could come from this.

TfL IS not-for-profit. I.E. any profit it gets is reinvested in London's transport infrastructure.

Sky News hasn't really done any investigative reporting here, the information is publicly available and most interested people knew about this project years ago.

Without recognising single persons, it would be much harder. You would have to consider that a person twice as close to the camera takes up 2x as much room as someone 2x further away. Generally, it can also be very hard to see people on a crowded platform and you can almost double the amount of people on the platform and see as little of the platform after as you did before. Wifi will probably generate better customers in that case. Add in the fact that you are still processing visual data and that you will get a lot of media attention and Londoners will lose trust in your services and you have a definite no-go for your project.

I believe that some more modern trains allow TfL to measure the weight change of carriages under passenger load, which can be used to estimate numbers, but imagine the cost of trying to roll that out on all trains and platforms... The fares would have to double for a year at least.

LU is pseudo-private. It falls under TfL, which falls under the London Mayor.

This has been suggested before, but the media exploded - people don't want to have visual recognition systems looking at them.

When TfL have previously suggested visual recognition software, the media exploded. So they took a step back.

Only access point connection time, hashed MAC address and time are logged.

The only thing that can be found out about anyone, is where they were, at what time, possibly who they were (all of which can be obtained from CCTV footage), and (additionally) how many web requests were made.

No browsing data is stored.

This doesn't particularly change the state of existing LU monitoring.

This is currently the only method available to get good estimates of # of people on a platform - unless you would prefer visual recognition software.

TfL needs this information to be able to stop overcrowding on platforms.

for the ambience. The pictures were taken on a mobile phone. They may also be particularly small if you are viewing them on a small device.

well, it looks like they're similar

is it not the same as this? https://www.youtube.com/watch?v=5RnuIiaLxCs

Nice find! I know what I'll be watching when I get home

That min file could easily be minimised further....

done

How are the topics assigned? Two Show HN posts I have posted recently (that are Open-Source and Javascript) don't have the relevant tags attached and I can't see a way of attaching them.

This sounds like an awful distraction
