GPS Log Analysis Uncovers Millions In NYC Taxi Overcharges

Hugh Pickens writes "The NY Times reports that New York City's Taxi and Limousine Commission is using GPS data collected in every cab to review millions of trips in New York City over the past 26 months and has discovered a huge number in which out-of-city rates, twice the rate charged for rides in the five boroughs, were improperly charged. The drivers' scheme, the commission says, involved 1.8 million rides and cost passengers an average of $4 to $5 extra per trip when drivers flipped switches on their meters that kicked in the higher rates, costing New York City riders a total of $8.3 million. Cab drivers are supposed to charge the higher rate only when they cross the border between New York City and Nassau or Westchester. 'We have not seen anything quite this pervasive,' said Matthew W. Daus, the taxi and limousine commissioner. 'It's very disturbing.' The taxi industry vigorously challenged the city's findings, saying it was unimaginable that such a pervasive problem could be the result of deliberate fraud. The commission says that 75% out of the city's 48,000 drivers had applied the higher rate at least once. Officials hope to roll out a short-term fix in two or three weeks in which an alert will appear on the backseat monitor when a cabbie activates the out-of-town rate."

      This is a tricky point for me.

      As our information collection gets better, hidden income sources get eliminated.
      Then the question becomes- does the "honest" rate really need to be raised?

      For example- truck drivers used to be expected to make 8 stops and were paid 8x dollars.

      Once GPS came in, suddenly they are being expected to make 11 stops (because the gps showed they were sitting around for 20 minutes) and work 100% while on. But the pay is still 8x dollars.

      I wonder if there is a correlation between how much the out of town rate was activated and how slow a day the driver was having?

      Our drivers in Houston are certainly not retiring wealthy (unlike some of our police sergeants). Cab driving should provide a decent living and with government intervention in rates, that can be tricky at times.

      There's an easy solution to that which involves neither GPS tracking nor micromanagement.

      Pay the drivers on a per-delivery basis, allowing for things like distance driven and amount or weight of cargo to be variables that determine this rate. Then the drivers can decide how they wish to use that 20 minutes. If a driver can make 11 deliveries in X time, then he gets paid about 28% more than a driver who makes 8 deliveries in X time. Now they have an incentive to be more productive that doesn't require tagging them like cattle and any expenses associated with that. The recipients of the deliveries have no incentive to help the drivers cheat this system, since that would mean failing to receive their items.

      The most robust solution to this is presented in the summary. Have some unambiguous indicator that allows the paying passenger to see whether the out-of-town rate is being applied. It could be as simple as a bright LED with a label saying "When light is on, out-of-town rates are being applied" that is tied to the driver's rate switch. This would guard against both deliberate deception and honest mistakes and would represent full disclosure to the customer.

      The idea of using GPS to monitor everyone's whereabouts and track their activities is both unnecessary and needlessly complex. Simpler, more robust solutions can be implemented that come with none of the privacy concerns. Not only is a centralized GPS database a tempting target for attackers who would compromise it, it's also a single point of failure if such a compromise does occur. That's undesirable in a system used to keep people honest. It'd be far more difficult to obtain physical access to every cab in NYC and disable the physical indicator of which rate is being applied.

      With that you get drivers rushing through their deliveries or trying to squeeze in an extra one or two runs per day. That's great and all and everyone wins, right? Until a driver that's taking drugs for alertness has a heart attack or one that doesn't falls asleep at the wheel. Cargo gets manhandled, customers get lousy service from cranky and rushed drivers, and the equipment takes a lot of abuse. The DEA starts sniffing around the employee lockers and trucks, insurance companies, workman's comp. adjusters, and lawsuit happy attorneys circle nearby.

      The other suggestions (the LED one) I'm in favor of. Let the customer know he's (possibly) being cheated, and they can work it out from there.

      "That's hardly fair to the driver, as being stuck in a traffic jam costs them more - and there are plenty of unforeseen events, such as detours for construction work or accidents."

      Unforeseen events tend to average out. So taxi company just adds a couple of percents to the price to compensate for it.

      Indeed, NYC created a taxi monopoly in 1937, partially as a response to poorly maintained vehicles and their attendant dangers. The problem is, that the law which did so hasn't been revised since, we've only had several hundred new medallions issued (as far as I know given for hybrid cabs) since 1937, and are stuck with the same ~13k cabs. Since this has made the medallions extremely valuable ($500k+), there is obviously a significant lobbying interest to prevent the sale of new medallions. While I'm not a huge fan of gypsy cabs (which, for example, often don't have functioning seat belts) the idea that the current population is served by the same number of cabs as was available in 1937 is absurd.

      Where do you get the baseline data? How do you control for delivery complexity? How do you determine pay? What do you 'expect' your drivers to handle? How do you handle owner-ops vs. leased trucks? Accidents? Training? Maintenance? What about drivers that perform significantly below the norm -- you're paying them fairly by your own standards, but you're incurring the overhead of maintaining their paperwork. How do you handle long deliveries vs. short deliveries? Hazardous cargo? Insurance? Benefits?

      They're already subjected to so much tracking, Cops ticket them first and only, they can't talk on cell phones now you want to automate them pushing one single button because you feel you can't trust them just that much?

      I think you fail to appreciate the sequence of events here. There's every reason to trust them, up until you find hard data showing that they have been overcharging. That is what happened. At this point, it's quite reasonable to want some verification. Automation isn't necessary either. All you need is a clear, unambiguous on/off indicator to let the customer know whether the out-of-town rate in question is being applied. Why wouldn't you want that to be done openly?

      Hell all the cabs now have a computer with screen that shows you exactly what your being charged for with instructions the second you sit in the seat detailing all the fairs. You get cheated I say it's your own fault.

      As long as this system makes it easy to unambiguously determine, at a glance, whether or not the out-of-town rate is being applied, then yeah that's rather silly of the passenger not to take notice. It'd be your standard failure to perform due diligence. If such systems are already in place and are already a standard feature, then the next step would be to determine why so many customers have been unaware of the information they are intended to provide.

  7. 1.8 million incidents out of 360 million trips by j1m+5n0w · · Score: 4, Insightful

    The 1.8 million fares represent a tiny fraction of a total 360 million trips over the 26-month period in question.

    Taxi drivers are people. People make mistakes. One mistake per two hundred trips does not seem unreasonable, especially considering that the frequency of incidents per driver probably follows a power-law distribution and the median number of mistakes per driver is likely much lower. Another way of looking at it is that 25% of drivers didn't make a single mistake in more than two years of driving.

    Which isn't to say that these were all honest mistakes. However, I don't see this as the massive systematic fraud the article seems to be suggestion. A 0.5% chance of being overcharged just doesn't seem like something to get excited about (even if I lived in New York, which I don't).

  8. The Taxicab Story in Washington, DC by GTarrant · · Score: 5, Insightful

    In Washington, DC, taxicabs used to charge via a "zone" system - it didn't matter how far you went (necessarily) - the city was divided into multiple "zones", and the rate was charged based on how many zones you had to travel through to get to your destination.

    People (particularly tourists) complained about this system because it didn't make complete sense and a tourist, or even just someone not familiar with the zone map, wasn't going to be able to look at the map and see where the zone boundaries were. As an example, if I was in a hurry, I could take a taxi from my home, to work. The total was 3 zones (with a minimum, of course, of 1). However, if I walked 1 block south from home, hailed a taxi, and had it drop me off 1 block north of work, it would be 1 zone. That would save a good percentage of the cab fare.

    However, a tourist getting in the car would have no idea - furthermore, if a tourist was being dropped off, say, right near a border, if the cabbie says "Hey, traffic is bad here, mind if I drop you off across the street?" most people would say "OK", figuring that in most cities, that's probably nothing, or maybe an extra quarter or so. In DC, it could be an extra $2.

    A little over a year ago DC switched to a metered taxi system, as mandated by Congress. Prior to the switchover, taxi drivers in DC went on strike, saying they'd lose significant money in a switch, despite the fact that the rates were set such that the average metered trip would actually net more for the driver than the old zone system would - but only under the assumption (which the people setting the rates were using) that the zone system was being used fairly and customers were not being diverted, sometimes only short distances, in order to add zones (sometimes, near zone borders, moving a few blocks could be two extra zones!).

    You'd get a constant circle:

    Taxi Driver Committee Representative: "We'll lose tons of money switching to meters!"

    Taxicab Commission: "But under this new system, a driver would actually be getting more money on an average trip than before, unless they were routinely cheating customers in a way the new system would prevent. Look, we'll open the books to you, examine the whole thing."

    Taxi Driver Committee Representative: "Ah. I see. We, of course, have never cheated anyone. But notwithstanding that, we'll lose tons of money!"

    The change took place anyway, and the world hasn't ended, although the data does seem to reflect that cabdrivers are making less than before, yet somehow the data also shows that they're making more per trip than before. How? Because before they were manipulating the system to charge more.

    I doubt this is any different. Most people in the cab in NYC aren't going to notice if the fare is $X or $X+4, unless they're a native. Just like I could tell my cabdriver in DC "No, drop me off here" whenever they tried to move an extra block near a zone boundary, a native might catch it. But someone unfamiliar? No. Thus, I'm going to side with the GPS on this one.
