British Village Requests Removal From GPS Maps 539

longacre writes "The tiny village of Barrow Gurney, England, has asked GPS map publisher Tele Atlas to remove them from the company's maps. The reason: truck drivers using GPS navigation devices are being directed to drive through the town despite the roads being too narrow for sidewalks, which has led to numerous accidents. At the root of the problem lies the fact that the navigation maps used by trucks are the same as those used by passenger cars, and they don't contain data on road width or no-truck zones. Tele Atlas says they will release truck-appropriate databases at some point, but until then they advise local governments to make use of a technology dating back to the Romans: road signs."

        To me, it sounds like a rare instance of authorities caring more about safety than money. Unfortunately, your attitude seems to be more common - to the point that some communities (*cough*Union City, CA [thenewspaper.com]*cough) have been caught deliberately and illegally causing unsafe situations in order to increase revenue from traffic violations.

        Just to clarify things a little...
        I've lived most of my life in the village next door to Barrow Gurney. It's barely a village, approximately 400 people... As for law enforcement, it's the local Women's Institute, frowning upon any anti-social behaviour and gossiping people to death.

        I used to visit the abbattoir there regularly for fresh meat (braaaiinnns....) but since it shut down, there's no longer and point to visit. Should it disappear off the map, I'm not sure anyone else would mind (apparently including those who live there). :)

        In regard to the actual situation in hand, I can confirm that it's a great shortcut for getting round the area "off-piste". The road section in the main part of Barrow Gurney is very, very wide and would fit several lorries in no problem. The only difficulty is that the rest of the village and all access to it is via narrow lanes (for you Americans read: tarmac'd footpaths) and can get a little hairy even in a car.

          It doesn't matter if you design the thing to block and be hit by a truck reasonably safely and not serve any other function.

          At the entry roads to the village put up barriers that will block vehicles above a certain height. Most trucks are taller than normal vehicles that would fit.

          Or set up a chicane designed to block vehicles which won't make it through the village.

          Then put up a big traffic sign with red circle and a red slash across it with a symbol of a truck inside the circle - "No trucks". This is so you can justify the fines etc to drivers that ignore it and hit the barriers/chicane.

          It's better to have the trucks stuck outside the village than inside the village - damage to stuff that's designed to take the damage, easier to clean up the mess, doesn't affect village as much, etc.

          If you're lucky you might be able to place the barriers where it's much easier to tow the trucks away.

        Hmm, not always... reminds me of a story. A truck driver underestimated the height of his trailer and promptly got stuck under a bridge. As a huge traffic jam swelled up behind, the truck driver and sheriff walked around the truck, rubbing their chins. The driver tried reversing, but got only tyre spin and fould smelling smoke. It was really stuck.

        A motorist walked up and introduced himself as; "John Cooper, I helped design this bridge, maybe I can help".

        Much walking around, chin rubbing and head scratching ensued, amidst the spiraling honking and abuse.

        "I think we're going to have to bring in hydraulic lifts and raise the bridge slightly" Said John Cooper.

        "Ungh, my boss ain't gonna like that" Said the truck driver.

        Just then, a kid, riding by on his bike stopped, dismounted, took of his cap (this was before compulsory bicycle helmets), looked up and down and said...

They pay no attention to street lights, they simply blow their horn and if your lucky you get out of the way. My father wasn't so lucky a few years back.

        There once was a time when most trucks had TWO people in the cabin, the driver and the "bijrijder" (no idea what the english word his, but his job is to lend a hand). There also used to be "relaxed" schedules. Upon arrival the trucker would be directed to the kantine and be given real coffee and perhaps something to eat while his truck was loaded/unloaded.

        Nowadays even trucks with frequent stops and for innercity work do NOT have a "bijrijder", an extra set of eyes, a person who can go out of the cabin and direct traffic, a person who keeps the driver awake and alert. The schedules are intense while the number of delays has only increased. Unless the loading/unloading is at a wharehouse the trucker now often has to help with the loading/unloading.

        This all makes for drivers who are tired, overworked and in constant fear of their jobs being taken by whatever is the next low wage country where none of the rules apply.

        All in pursuit of the almighty buck. Notice how especially trucks from companies like DHL and other delivery firms that are always pushing the limits drive incredibly unsafely. I know how the routine goes, deliver 100 packages and next day they give you 110. Deliver them, and you get 120. Traffic jam? Just work overtime, that is increasinly hard to get overtime PAY for. The odd thing is that if you look at maintenance records this practive is very bad as the trucks are pushed way too hard and this actually costs a lot of money. Plus the invevitable accidents really start to affect business.

        But hey, the package has to be delivered NOW and for as little money as possible.

        That is the reason many truckers are a danger on the road.

        It is the same reason tech support (who are on orders to handle as many calls as possible) often just says "reboot/reinstall" and tries to hangup.

        Want good service/behaviour? Stop squeezing the margins, introduce strict laws and make sure people ain't forced to push the limits just to make a living, because they won't always get it right and a rude tech support guy is bad enough but an asleep driver of a truck is another thing altogether.

    This being slashdot, I'm expecting lots of people to post either agreeing that a few road signs are all that's needed, or some sort of opposite position, like hide the signs behind bushes and then ticket the hell out of the truckers.
            The real problem is, for every trucker that actually is clueless and 'innocently' relies totally on the GPS info, there's another one who has heard the road is too narrow and difficult for trucks, but will try it anyway, and then claim he never heard any other driver say differently. The ones that will lie like hell about having foreknowledge are also the ones who will claim they made the decision to go that way based only on GPS info, and they assumed the GPS wouldn't mislead them. They may well claim that their dispatcher didn't say anything either, to shield their firm from potential liability, and try to make it look like the gadjet is the real source of the whole problem.
          Now what happens if the truck didn't just clip a historic building or two (Which are pence a dozen in the UK), but, e.g., ran over a kid?
          This is really about the difference in UK and US law. In the US, there are plenty of precedents that let the child's parents sue the trucker's firm, the GPS maker, or whomever has the deepest pockets. In the UK, there's much less ability to extend liability to someone only peripherally involved. A tangled mess of a case, with lots of arguments about just who is responsible for what percentage of total damages, tends to result in much more modest settlements there. One thing both locations share is that all too often average people tend to assume a computer based system doesn't make mistakes.
            This means the town may be playing it smart - take away the GPS info, and the driver has to justify his decision based on paper maps, talking with the corporate dispatcher, or some other source of info, and if that's not a computer, the driver can't weasel out of much by claiming he assumed the source of info was infallible.

The government is considering allowing them in the UK, and according to BBC this morning they are currently on test at some small airport. The haulage companies say if approved they will only operate on motorways, but groups are already concerted about these trucks going through small towns,

    Make a bypass! Problem solved!

    What? There's a house in the way? You say it's owned by Arthur Dent?

    I'll get the byzantine paper trail started, go tell Prosser to fire up the bulldozer.
  • US truck routing programs like PC*Miler and IntelliRoute DO know about truck restrictions. Which means that on the Main Line in Pennsylvania, which has many train bridges less than 13" 6' above the roadway (one has under 9 feet clearance!), it's usually rental trucks which hit them rather than the big commercial ones...
  • I wholeheartedly sympathize with the residents of Barrow Gurney, because ever since the introduction of sat nav we've seen a large increase in the number of delivery lorries (mostly from builders yards) going past our house, and half the time scraping or banging into the drystone wall attached to our house because the road is so narrow. We've asked them why they travel down past our house instead of coming from the other end of our road to get where they were going, their answer almost every time: sat nav

    The put up physical barriers. At first I was rather confused when I saw these pillars and other barriers on different roads. And when I asked various people who live there, they often didn't know. But I guess it only takes one person to know to stop asking as I eventually got the answer. Roads that are too narrow in places for vehicles of larger sizes (those little 2/3s cars were usually okay everywhere) would likely cause problems if they were permitted.

    No one reads road signs... well some people do, but the risk and frequency of that happening is too high.

    The barrier method is both obvious and effective. The only reason it never occurred to me naturally is that we don't have those here in the US. The nearest thing similar in effect in my area are those pipe-grated things that are often found along country roads. Don't know what they are called, but they are used to keep live stock from walking out into the street. We also have various barrier devices similar to those of the Japanese, but they are used to protect buildings or obvious devices and structures, not block access to roads or weak bridges.

For God's sake, stop researching for a while and begin to think!
