back to article London Tube tracking trial may make commuting less miserable

The people in charge of the London Underground transport have released a report [PDF] in their month-long tracking trial of Tube users – and the results are fascinating. Transport for London (TfL) used Wi-Fi access points in 54 stations in central London in December last year to track nearly six million mobile phones, and …

    Sounds promising

      Re: Sounds promising

      I can recommend the 3rd party "Tube Assistant" app - although not sure if it can take advantage of live arrival information (if that's in any feed from TfL).

      It's very good at telling you the different route options and how long each route *should* take, plus where to sit/stand to minimise your travel to the exits from he station.

    This is actually an amazing piece of work. Privacy protection sounds first rate. But please

    No apps.

    Do you really need a few million of the clueless looking head down inside some of those stations?

    People will think "Signage, how quaint." But changing signs could cut 2 mins off the journey time of 1 million commuters is basically 3.8 years of journey time each day. Signage also keeps the visitor looking up, not down, so they're less likely to trip over someone.

    Alternatively discouraging some of those 17 odd routes should stop squeezing some of the severely congested stations during the rush hour. I wonder if tfl realized just how massive a surge some of those stations were getting who were not entering or leaving, but just passing through?

    This (in principle) is a microcosm of the concept of the "smart city." Using the passengers not to track them but as probes within the system and hence identify ways to improve the system.

    I applaud the results, but I doubt many other trials will be conducted so scrupulously. :-( That's the problem. But for now thumbs up.

      "Do you really need a few million of the clueless looking head down inside some of those stations?"

      They're already looking at their phones, why not give them a nice easy sat-nav type app which tells them exactly where to walk. That way they can point different individuals in different directions, perhaps routing that tourist family on a slightly longer journey so they don't have to get mixed up with all the commuters.

    "It may even be possible for TfL to update commuters in real time about a faster or less crowded route to their destination,"

    I wonder whether that would suffer from oscillations. The less crowded route then becomes the most crowded one. That state being advertised then switches the load back to the first one.

    Any app or signage would have to be selective about how many passengers it told about an updated route.

      I have seen people take the tube from Warren Street to Goodge Street - I'm sure that the walking into/out of the stations is further than the distance between the stations.

      The other one that gets me (now that I arrive at Euston) is the convoluted route to get to Euston Square - it's a short walk along Euston Road, or multiple changes on the tube, so which does TfL recommend?

        "the convoluted route to get to Euston Square - it's a short walk along Euston Road"

        Presumably you mean Euston Square tube station - Euston Square itself is just in front of Euston railway station. Euston Square tube station used to be called Gower Street which was appropriate because that's where the entrance is. When it was renamed Euston Square it really should have been provided with entrances & exits at the Euston end of the platform.

        Back in the days when I commuted into Marylebone or Paddington to work very near Euston the route I'd take depended on the weather, something TfL should take into account. On wet days it would be the longer route via Oxford Circus on the Bakerloo & Northern lines to avoid as much walking outside as possible.

        And whilst we're about it, rather than the cavernous concourse at Euston, why not split the holding space for arrivals and departures on to two floors with ramps leading down to the platforms, so that arriving passengers aren't fighting their way through the massive crowds waiting for the 16:47 London Midland calling at all stops to pergatory and the queues for Burger King?

      Yes. The TFL route finder will flag when a connection can be walked, but the problem is many of these walking connections count as tapping out and then tapping back in, so if you don't have a travelcard or aren't hitting the daily cap that's two journeys you'll be charged for. There are a small number of connections where tapping out at one station and tapping in at another won't be charged, but frankly unless you work for Londonist remembering where this is permitted is nigh on impossible.

        MAC address randomisation does absolutely nothing to protect you from being tracked - The system looks at which SSID's your device is trying to connect to!

          > The system looks at which SSID's your device is trying to connect to

          No, no, no - RTFReport:

          "When a mobile device such as a smartphone or tablet has WiFi enabled, it will search for a WiFi network to connect to. This involves the device sending out a probing request that contains an identifier specific to that device, known as a Media Access Control (MAC) address. If a WiFi network is

          found that is known to the device, it will automatically connect. If the device finds unknown networks, it lists these in the device settings so the user can decide which, if any, to connect to.

          During the pilot, if a device was near one of the 1,070 WiFi access points in the designated area, and it had WiFi enabled, we would have collected the request(s) to connect, even if the device did not subsequently do so."

          Every mobile with WiFi enabled transiting through TfL's system will be probing their APs, even if they don't register. This leaves a MAC address record in the AP, which is harvested with a timestamp. This happens in shopping malls and airports (at least) for footfall analysis and is a fairly standard feature in the boxes. TfL have merely put the information together from their many APs in a useful way.

          Last year TfL held a hackathon and exposed a wide variety of data feeds to the entrants (traffic light timings, road status information, traffic queues, ...). For all their flaws, they're being quite good at attempting to find ways to embetter their service offering.

      That was my first thought too on reading the article. It's no wonder so many get "battery anxiety". Since it's a phone with a data connection, I fail to see why having WiFi on would make a user think they might be missing out on something unless they have such a poor data plan they are prepared to sacrifice a level of security by allowing their phone to connect to any old WiFi WAP they happen to be near, It does seem to be the vast majority of people too.

      It's easier to leave WiFi on and have it autoconnect to known networks, than be constatly turning it off.

      Perhaps the bigger problem is the high cost of data meaning WiFi is the preferred way to connect - would you like a 1GB tariff for £20 and use WiFi, or a 5GB tariff for £40 and save a few minutes of battery?

      I charge my phone each night, I haven't turned WiFi off since I bought it in May, only when I've been doing really daft things like playing games or watching video all day does it not last until I climb the wooden hill to Bedfordshire. What you're saying may have been true 7 years ago, but I think the way idle WiFi is handled now seems much more battery-friendly.

    Smartest route?

    "27 per cent used a completely different line and went through Green Park (to our mind the smartest route)."

    Oxford Circus is one of the few Underground stations that has different tube lines on adjacent platforms. To change from the southbound Victoria line to the southbound Bakerloo, you just get off the train and walk 20 yards from one platform to the other. No steps, no escalators and little congestion. Takes about 20 seconds

    To do the same at Green Park you have to go up stairs, through tunnels and down an escalator - takes about 5 mins and does congest the station.

    Seems unsurprising that the wisdom of crowds over hundreds of thousands of journeys, correctly selects the 'smartest route'.

    What is odd how many people actually do go via Green Park. The speed of the trains and the number of stops between start and end stations is usually far outweighed by the interchange time or how long it takes to get up and down from the platforms. Changing at Oxford Circus is therefore 5-10 mins quicker.

    However the tube map makes it look like they ought to be about the same distance only with fewer stops via Green Park, so going on the map alone, Green Park perhaps feels like it ought to be faster.

    1. Ivan Headache

      Re: Smartest route?

      If I can I avoid changing lines at Green Park. There is far too much walking to do.

      Oxford Circus is an interchange I use a lot (B to V lines generally) but I find that the signage in the station absolutely awful when using the Central line (or trying to get out).

      For me (I don't go into the city very much so I'm not counting those stations) the worst pinch point is the tunnel from the Paddington station side ticket hall to the D&C platforms - particularly the westbound platform. When the Heathrow Express was planned they should have given some thought to the plight of foreign visitors with all their luggage struggling up a (invariably blocked) narrow staircase and then down another.

      It will only get worse once Crossrail is runnung.

      1. anothercynic Silver badge

        Re: Smartest route?

        Actually Crossrail could make it *easier*, certainly for those who have to use the Jubilee, Bakerloo, Central, Northern and the southern half of the Circle and District lines, mostly because you can get to those lines by staying on the Liz Line to Bond Street (Jubilee, Central), Tottenham Court Road (Northen, Central), Farringdon and Liverpool Street stations. The speed on the Liz should make transfers easier than sitting on the Tube.

    2. yuleblucky

      Re: Smartest route?

      If you have to change at Green Park it's quicker to go up to the booking hall and back down again than to follow the signs through the labyrinth.

      If you need to change from the Northern line southbound at Euston to Victoria Line do it on the City branch as it's only 50 metres at most - no stairs or anything.

      They're not looking at the journey as a whole, but station transits within a journey. Oyster and ticket data already tell them exactly how many people do each journey in terms of stop-to-stop.

    NB: tracking Oyster cards means tracking regular commuters, not occasional visitors, tourists, and such, so that is also biased.

    Actually, I wonder if the "WiFi-on" populations has a disproportionally large fraction of foreigners who do not have mobile data plans and are happy for any free WiFi between sights? [Not a Londoner and my WiFi is usually off, so I don't even know if you can register on the TfL WiFi with a foreign mobile number.]

      Re: So the study tracks...

      The proportion of commuters that don't have a smartphone and don't have wifi turned on is practically zero, as anyone who uses the tube will be able to tell you. Most travellers at peak times are connected to the free wifi and those that aren't almost certainly haven't bothered to turn their wifi off.

      And no, tracking Oysters doesn't exclude occasional tourists, visitors and such. Tourists use Oyster too. If they don't they use paper tickets. The only people who cant be tracked across multiple journeys are people buying and discarding paper-based single tickets. Given that's anywhere up to six times the cost of Oyster that is, again, going to be insignificant.

      Well, duh.

        Re: So the study tracks...

        The main group of people using paper tickets are people who live outside London who buy an all zones travel card as part of their rail ticket. There's been some work on integrating with the ITSO systems used outside of London, but I'm not sure how that is progressing.

    TFL do some things well.

    They are one of the very few organisations I allow to send me emails on a regular basis.

    They don't spam, I get one email a week with weekend disruption due to engineering works and the very occasional email for an extraordinary disruption.

    The emails are informative and useful to me and they don't take the piss by spamming me with crap.

    The website for bus arrivals could be a bit quicker IMHO but it does work well.

    That in effect makes it impossible to know what the original MAC address was

    sure, and the "relevant" law enforcement agencies were like, TOTALLY uninsterested. No sir, OF COURSE we don't care how we can get our fingers on such data if and WHEN...

      Re: That in effect makes it impossible to know what the original MAC address was

      I tend to agree, even though you've attracted downvotes. Everyone seems happy to congratulate TFL. I don't see how collecting personal information (MAC address and location) without consent is legal. The law says you can't do it, not that you can do it as long as you anonymise it eventually.

      Would you all feel the same way if this were Google collecting information without consent from all Android devices?

        Is it personal data?

        Surely it only identifies you as a person if your MAC address has been tied to your identity, otherwise it's just a (hopefully) unique key.

        I'm not aware of any mass-collection of this data, I don't believe there's a way of knowing that if I'm carrying DE:AD:BE:EF:12:34 in my pocket, then I'm Bob Smith, of 55 The High Street in Lower Peover. Certainly I work for a mobile network and it's not captured at point of sale.

        (Obviously I'm ruling out services like TheCloud where you might have signed up, with your MAC and personal details, to access the service. However TfL haven't said that they're using external data and for once, given they seem to have a pretty good idea about what they can and can't do, can't we just believe them?)

    Since Waterloo - Kings Cross is the only tube journey I do anything like regularly:

    - Via Oxford Circus is undoubtedly the best option. The Victoria Line was specifically routed to allow quick step-free connections to the Bakerloo line there.

    - The slowest bit of the journey is due to the signage at Kings Cross, which directs you down a newish feels-like-half-a-mile tunnel to the "Northern Ticket Hall". If instead you get off the Victoria Line train and follow the signs for the circle line you'll end up in the old ticket hall, and and you'll be out much faster.

    I don't often travel at rush hour, so best options may be different then due to congestion.

    Delay by design

    My experiences of the tube was that there seemed very deliberate efforts, via signs and general herd movement, to get people to walk the slightly longer route. The quick route is there for those that know it, and if 20-30% of the rush hour uses it, things don't get congested. But if 40% or more of the rush hour traffic uses it, then congestion problems occur.

    Learning each station's quick route and which end of the train you're aiming for is part of the charm :)

    Asking a pair of city dwellers "what's the fastest way A to B?" is always good for a laugh. Parisians and Romans are great, but for getting a couple of Londoners arguing, ideally when others start chipping in, is great for an icebreaker.

    My vote is on Oxford Circus, cross tube platforms are just grand.

      Re: Delay by design

      Oh yes. Walk into Monument and follow the signs to the Northern line (and proibably DLR) and you'll end up going all over the place through a warren of tunnels and it will take you a good few minutes. However a more direct route is to walk down to the Eastbound Disctrict/Circle platform then proceed to the Northern line.

      Obviously they don't want the corridor that links the N and D/C lines to become completly clogged, but the official route is somewhat round the houses.

    Do you seriously make sure you switch wifi off every time you leave the house / office / girlfriends house....
    No. I only have it on when I want to use it (same for mobile data). That means when I am looking at it...

I bet you don't ever watch TV except for the odd documentary about Gregorian Chant, and you believe central heating should be controlled by an on-off switch, not a thermostat.

    Non-Londoner (Or Indeed British) Question

    "TfL already tracks its passengers using the electronic Oyster card, which a huge percentage of Londoners use out of convenience and cost on their daily commute. But that data only tells the transport folk where people go into stations, where they exit, and any transfers they make to other lines."

    The card tracks the exits? I'm trying to picture the method, and failing. In my city's system, all an exit has is a one-way turnstile -- it doesn't track or require a card to exit. What am I missing?

      Re: Non-Londoner (Or Indeed British) Question

      Your city obviously doesn't use point-to-point billing. With an oyster card you either 'tap out' of a turnstile in exactly the same way you 'tap in', or the system assumes you took the most expensive possible journey and are trying to dodge paying for it. Then bills your card accordingly. So you very rarely get journeys of the form [In at Turnstile x]->[Out at 'unknown']

    2. David Nash Silver badge

      Re: Non-Londoner (Or Indeed British) Question

      Presumably in your city the length of the journey does not affect the price charged.

      In London it does, so you touch in and touch out and the system knows where you entered and where you exited and consequently the length of the journey (zone-based) for which it has to charge you.

      Same applies when using contactless payment cards on London underground. You have to touch your payment card again when you leave and it figures out how much to charge.
