Using GPS to Hail Cabs

The Benefactor writes "The guys at The Register are running a story about using mobile phones to hail cabs in London. Using GPS technology to locate the nearest available cab and to direct it to where you call from this should make frantic arm waving to get their attention a thing of the past."

  1. Actually they aren't using GPS at all by Harald+Paulsen · · Score: 5, Informative

    They're using GSM-based location-services that many cellphone-providers across europe are starting to provide. GSM is the european standard for digital cellphones, and you can't get an exact position, only tell which base station the caller is connected to. Therefore you can find people in the same area by matching which base-station sees which users.

      You can get a more accurate fix on someone's location than just the base station they're using. The base station knows (to within 500m) the distance to your phone for setting time delays. Also, base stations are often in 3 segments.

      In addition, base stations can use multiple receiving antennas and triangulate based off the relative phase at each antenna. Positioning to within a few 10s of metres is feasible then. This is becoming compulsory in the US, for the E-911 service.

    It's been decades since the London fog was so bad that you would need GPS to flag down a cab. They can see you on the streets. You're the tourist dressed wearing the Princess Di T-shirt with an overpriced camera around your neck jumping and waving frantically.

    A GPS signal might help them find you when you can't tell them where you are, which, for most non-Londoners (and many residents), is quite common, but it ain't about to replace flagging down the cab that you can see driving down the street.

    Black Cabs (Taxis) are allowed to pick up passengers anywhere, i.e be flagged down. They have to pay a fair bit for the licence which allows them to do this. Mini Cabs (Private Hire) have to be booked and must pick you up from a pre-arranged location. AFAIK, there is no reason that you cannot book a Black Cab, though perhaps the hotel staff gets a better backhander from the mini cabs.

  10. Re:Black cabs and minicabs by Anonymous Coward · · Score: 5, Informative

    This is a result of a set of truely great rules about London Cabs that have evolved over centuries called the Hackney Carriage Rules.

    To be a Licensed London Black Cab the vehicle needs to be able to do some extreme things that a normal car can't do - such as do a U-turn in about a 20-foot circle. That is why all the 'Black' Cabs in London are not based on normal cars. Black Cab drivers also need to pass 'The Knowledge'

    Minicabs are a relatively recent invention (70's I think) which are NOT allowed to be hailed on the street, have much simpler vehicle rules and the drivers don't have to do 'the knowledge'. Minicabs (legal) can often be pretty grotty. Often you get unlicensed (illegal) minicabs hanging outside pubs and clubs - these can be even more dodgy.

    'The knowledge' is the about 2 years full-time work needed to know all the required addresses and routes in London. You cannot drive a London Black Cab without doing this. Becoming a Black Cab driver in London is therefore a pretty serious long term commitment.

    (Rampant half-cocked conspiracy theory)

    No it's the company's management trying to figure out a way to eliminate cabbies. Think about it, if they don't have to loiter waiting for a fare, and instead are directed from point to point by central dispatching, you can theoretically do the same work with fewer cabs.

    Not only that, but cabs are drawn to people of credit sufficient to be carrying mobile phones.

    Except of course:

    • They are already making money hand over fist
    • They DON'T pay the cabbies when they aren't collecting fares
    • From what I understand, the cabbies pay for fuel
    • Mobile phones are so cheap they are practically giving them away with breakfast cereal.
    So my theory doesn't make sense from a business standpoint. But what a great conspiracy though...

    Of course that's not the real problem. At least here in DC, I play a constant game of hopping in and out of cabs until I find a driver willing to take me to my neighborhood. It's not tough at all to hail a cab while you're downtown, the problem is finding a driver who is willing to take you to a neighborhood that he considers dangerous (or at least unlikely to result in a return fare). You can get that cab downtown/in the tourist areas real easy - but just watch how fast he'll work to get you out of his cab if it turns out he doesn't want to drive where you've asked him to take you. What we could really use is a system that not only tells a driver where you are but lets him know in advance where you'd like to go. Then I wouldn't have to spend a half-hour boucing in and out of cabs until I find a driver willing to take me home.

  15. Could be more appealing to the minicab operators? by scottme · · Score: 3, Informative

    In London, only the licensed black cabs are permitted to to pick up passengers who hail them on the street. But there are also armies of more-or-less-dodgy minicab operators who work on the basis that the car is pre-ordered, by the customer calling the minicab company's office, who dispatch a car to you by radio.

    This new system sounds like it would be ideal for the minicab operators, because a punter calling in and using this service is in effect ordering the car as opposed to hailing it on the street, yet the turnaround time should be a lot quicker.

    The black cab drivers are going to hate this...

    And I'm not kidding either. The streets of Manhattan are so thick with yellow cabs that it rarely takes more than a wink or a nod for them to pull over.

    It's gotten to the point where cabbies will see me walking out of my building a block away, honk their horn a few times to get my attention, and then I can respond with - literally - a tilt of the head or a slight shake and they're off.

    So in NYC, this isn't going to do much good most of the time.

    Is this really a problem? I've never been to London, but any city I have been to, the cabs were almost frantic to pull over and let you in. In New York, I've had cabbies pull over and ask if I wanted a ride when I was just standing there.

    You need to know about "cabs" in London. First there are two kinds, proper cabs, or "black cabs" as they are often called (actually hackney carriages but I digress). Currently these require a specifically authorised vehicle with disabled access, insurance, regular maintenance, etc, etc and above all else a licensed driver who has passed "The Knowledge" by which they should be able to know any street within a 6 mile radius of Charing Cross. Yes, and that is pretty much actually true, get in the back, give an address and they will be able to get you there without referring to a map (it's pretty incredible), for this you pay a premium price.

    Then there is mini-cab scum, which can basically be a bloke and a car, and that's about it, you negotiate price with varying rates of success based on time of day, distance, number of passengers, liklehood of one of the passengers despoiling the vehicle and blood alcohol level of both driver and passenger. There is virtually no regulation of this service. Very scary

    In between these two are more reputable mini-cab firms, not the knowledge of the black cabs but not quite so dodgy as the bloke on the street, but here to there is a lack of regulation and a sliding scale of reliability and competence from just above dodgy to as good as a black cab but without passing the knowledge (for a variety of reasons, some not so good).

    I have cabbed it all over the world from the grease covered toyota's of Jakarta, to hailing some guy with his groceries and wife and kids in a Lada in Moscow, to cabs of varying kinds in London. Black Cabs for all their faults offer the best service in the world (and much comedy value if one gets the right cabbie who would like to share with you his view on the current state of the world).
