This means while and where the speed limit is 50km/h, you will never get a ticket for less than 60km/h (except for public holidays where the grace is switched to 4km/h in an effort to curb the road toll). Part of the reason for the grace (apart from allowing for normal human error) is to account for possible errors that may occur in the measurement.

      Now that makes me think that if his average speed between the two points is estimated at 35mph and the areas speed limit is 50mph, with a similar grace that is one giant error in the system. (Since typing I've gone on to read that the grace is 12mph, which converts to 19km/h... in my opinion a huge leniency). The reason I feel it must be a glaring error is that the calibration of these devices, which I presume are radar would be far more precise than 19km/h. I would go on to guess that the 0.363 seconds between the photos is fairly accurate too, given that these devices are designed to be evidentially sound.

      So he's worked out he's going 35mph, he must have been going at least 62mph to activate the camera. 35mph is 15.6464m/s meaning that in 0.363 seconds he would have travelled 5.67m, 62mph is 27.71648m/s which would indicate he travelled 10.06m. There would also me a small amount of error in the reading due to the doppler shift going on in the radar that records his speed. The favour of the cosine coefficient from the doppler effect always goes to the advantage of the motorist. It seems to me that with all the possibilities to cause error, there is still one huge difference. So while I think that the error is actually in his use of photogrammetry, he must have done one big error and fooled the judge on it. He's worked it out too. As per the article "Mr. Foreman said he is awaiting trial on about 40 more tickets, all of which he called “bogus.”" He worked out he get off the tickets and now he speeds everywhere like a maniac no doubt. I just do not believe that there can be that large errors in the system so that leaves him behaving like an arrogant tosser who is a danger to all other drivers and especially pedestrians.

Regardless of how accurate or inaccurate the timestamps on the photos are, it's still a reasonable assumption that the camera will always take the two photos at roughly the same intervals.

      If not, slow down. And I don't mean "smash the brake pedal," but just decelerate some. If they persist, slow down more. Rinse and repeat as needed, while staying in the right-hand lane as much as possible.

      They will either get bored/pissed and pass you, or realize that they're not going to improve their rate of travel by persisting in following so closely and back off. (You can assist with them passing you by allowing a gap, and/or slowing down even more when they begin to pass to expedite the maneuver, and/or staying close to the berm so they can better see other traffic.)

      Either way, the tailgating situation is relieved, you can resume driving at a more normal speed quickly enough, and (perhaps most important) the actions of the cocksucker behind you won't result you getting a ticket.

So yes it makes sense to challenge the magnitude. If you get a ticket for 12 mph over the limit the fine is say $150 plus 2 points (numbers I'm pulling out of my ass but are fairly representative), now if the automated camera is adding 4 mph more on top that puts you at 16 mph over which would then put you at a $225 fine and 3 points.

      On a side note, as a designer of roads and bridges I can say that the speed limits are influenced by the geometry of the road and the location (i.e. while it may be geometrically possible it is a bad idea to have a residential street posted for 50 mph). There are some cases where unscrupulous towns/villages/cities will post a lower speed limit than the surrounding areas as a way to increase revenue. This is can be challenged court and is frequently overturned. Also in areas where there are lower posted speed limits for things like curves (black on yellow) and construction areas (black on orange) the lower limits per MUTCD are not enforceable as those signs particularly the black on yellow are just suggestions. To lower the posted limit the signs must be the standard regulatory black letters on white they can only jump 10 mph at a time (i.e. you can't go from a 45 to a 25 in one jump) and there must be advance warning signs "reduced speed ahead".

      Well just for fun, let's crunch some numbers.

      Ref: The Highway Code, HMSO. Sections 117 to 126, "Control of the Vehicle", subsection 126 "Stopping Distances".
      Disclaimer: some calculations done with WolframAlpha.

      Let's assume the posted limit is 40MPH. That means that in each second, the vehicle will travel 17.88 metres, or 58.67 feet.
      Now let's assume the vehicle is travelling at 60MPH. 26.82 metres per second, or 88ft/sec.
      In order to fool the GATSO, we have to be travelling at or below 40. That means we need to lose 20MPH.

      Thinking time at 60MPH is 18 metres, plus 55 metres for the vehicle to come to a complete stop.
      This means the assumed reaction time is about 0.67 seconds.

      The camera is 50ft down the road from the RADAR speed sensor (the GATSO itself).
      This means that in 50 feet (15.24 metres), we have to:
          * Realise the camera is there
          * Pull off what amounts to an all-out emergency stop (brakes hard down and fight against the Anti-Lock Braking system)
          * Lose 20MPH of speed
          * Release the brake before the camera goes off

      Let's say it actually takes 60 metres to stop the car. That means we lose 1MPH for every metre travelled. Thus, 20 metres travelled. 0.75 seconds.

      So if it takes a human 0.67 seconds to realise "Aargh, that's a GATSO" and slam the anchors on, plus a further 0.75 seconds to slow down sufficiently, the vehicle needs to be at least (0.67 + 0.75) = 1.42 seconds away. Working backwards, we get 124.96 feet, or 38.08 metres. Add a bit for the guy to release the brake before the camera flashes and this just doesn't hold water... we're talking about 45 or 50 metres total.

      So based on our previous assumptions:
          * The vehicle is travelling at 60MPH
          * The speed limit is 40MPH
          * The driver has an average reaction time per the Highway Code baseline standard

      There is no way an average person, in an average car, could slow down sufficiently in 50 feet to get a positive hit on the RADAR, but get a negative on the photo. An F1 or WRC rally driver with a full Advanced Driving license, experience and lightning-fast reactions, driving a shiny new sports car *might* be able to pull it off, but not your average Joe Q.

      The car looks like an Explorer, and the published specs for a Ford Explorer are 60-0 in 125 ft (-0.96 g's for 2.8 seconds), so definitely plausible that the car decelerated from 50mph to 35mph in 50 feet by pulling -0.85g's for 0.8 seconds, since the car is capable of pulled -0.96 g's for 0.71 seconds in 44 feet. This would give him more time to take his foot off the brake pedal.

      However, the camera trigger is probably based on time rather than distance, so "approximately 50 feet" is about 0.7s at 50 mph or 1.0s at 35 mph. The police could still prove their case by overlaying several photos of different cars that were *actually* traveling 35mph and 50mph. Regardless of the delay used (in the range of 0.7s to 1.0s), the 50mph car would be about a car length ahead of the 35mph car, and car that decelerated 50-to-35 would be about half-way between the 35 and 50mph cars, so it would be very easy to show that the guy slammed on the brakes.

      p.s. * = There's a foreground bush in the first image not present in the second image, and the gammas differ by about 20%, but aligning the tree shadows on the road makes it pretty clear that the car only moved slightly more than one car length (15 ft) in 0.363 seconds between the images = approximately 28-32 mph by my guess, as opposed to the 35mph quoted in the article.

      Yes. A fine "proof", except for one thing. Well, maybe several that all point to one big problem.

      1. For the sensor to measure speed in a specific speed zone, the sensor has to be IN the zone.
      2. For the speed zone to be valid, it has to be marked.
      3. The marking has to be visible prior to entering the zone.
      4. Thus, the driver is aware of the change of speed limit prior to the entrance to the speed zone, and well before he reaches the sensor.
      5. He has plenty of time to react to the new speed zone prior to realizing there is a speed camera in operation.

      The correct point to begin measuring the reaction time/distance is not when he passes the sensor, but when he first realizes that there is a speed zone which requires him to slow down. That may be quite a distance before the sensor.

      Further, the devices are installed only in school zones, according to TFA. School zones are usually well known, especially by local drivers. In other words, they know about them and where they are in advance of seeing the speed limit posting.

      Is it possible for someone to start slowing from, say, 60 MPH before reaching the speed zone, cross the sensor at 50MPH, and then be going 35 MPH fifty feet later? I would think so.

      A great deal has been made about the lack of taillights, but TFA says that they "typically" aren't on. That means they sometimes are on.

      And finally, the problem of slowing down a truck has been raised. Most diesel trucks I know of can make use of engine-assisted braking. I.e., you don't have to step on the brakes to slow down, you let the diesel engine compression do it for you.

      For those who would argue that the timestamps make the system defective, just how accurate must a timestamp be before you'll accept the system as valid? Millisecond? Microsecond? Tenth of second? Does a picture that is intended only to show the presence of a vehicle in the target zone at a particular time have to be more accurate than one second? How many people have been arguing about how short a time there is between sensor and camera as proof that the vehicle couldn't have been going 50, and yet demand microsecond resolution for determining which vehicle was being measured?

      The government intentionally posts low speed limits so everyone is guilty. Once everyone is guilty, they are free to pull over anyone, at any time, for any reason, and cite "speeding" as the reason.

Similarly, I lost control and totaled my last car when I was going 25 mph under the limit on an interstate.

    However, it does become a problem if certain traffic flows are expected to pass a certain stretches of the road in a certain amount of time. Traffic light timing might depend on traffic making it from A to B in 30 seconds, for example, so that by the time the last of that traffic hits point B, it opens traffic at point A up again.
    But if for that 30 seconds the cars should be going around 70mph, and the speed limit is actually 55mph.. well then the traffic will take 42 seconds to get from A to B. But at 30 seconds the traffic is opened at point A again, while point B gets closed - so some traffic doesn't make it through. Slowly but surely, traffic on that stretch of road builds up, until it's completely gridlocked.

    Which, of course, is exactly how too-low speed limits should be combated. Driving fast anyway and getting a ticket just means you're feeding somebody's revenue. Driving the speed limit and getting traffic locked up, requiring the local government to go send out cops to figure out why traffic is locked up, direct traffic, and listen to the talking heads on the local channels complaining of all the time and money lost by businesses due to the locked up traffic... that will get them to re-think those speed limits.

Something like that is not going to be subtle either, so don't expect to drive around for long without the cops noticing it. Same thing with those license plate covers that I sometimes see people put on their cars.

  45. Re: complaining about the extent of the speeding by Canonical+Coward · · Score: 1

    As well as the other replies you've already gotten, there's another factor here. When you're accused of a crime in a court of law, it has to be SPECIFIC. You're never issued a citation simply for "speeding", right? The officer puts down a specific speed. So the issue is; are you or aren't you guilty of the specific crime you're being accused of (which is driving X number of miles per hour in a Y speed limit zone).

    No. In all the jurisdictions of the US I'm familiar with, the crimes are not exclusive, they are inclusive. If you are charged with 60 is a 35, for example, that also includes 50 in a 35 and even 40 in a 35. You can't get off by claiming that you were "only going 55" in that 35 zone, because that's an admission of guilt to a violation and your charge can be modified to "55 in a 35" on the spot and you'll pay that fine. They won't charge you with "speeding", but they will charge you with "excessive speed: X in a Y", and the fact that X might be too high or too low isn't a remedy.

    They'd never charge you with "Theft of a car stereo valued at $239.95." They'd charge you with "Theft of a car stereo valued at under $500.")

    You're mistaking charges with specifications. The charge would be "misdemeanor larceny from a vehicle". The specifics would be "theft of a car stereo valued at less than X$ from ..."

  47. revenue for municipalities in Maryland by oneiros27 · · Score: 1

    First off, I'm an elected official in PG County, Maryland, and if I hadn't had a long day at work, I'd be at the PGCMA (Prince George's County Municipal Association) tonight, instead of reading slashdot.

    I haven't seen Forest Height's budget, so I don't know exactly how they have it in their budget; honestly, if they use the same auditors we do, we'd likely have to show 100% of the tickets as revenue, and 40% of the tickets as expense (to pay the company, assuming the rate in the article was accurate, which I don't know that it is, as it's my understanding that the practice isn't allowed under Maryland law), so the percentage might actually be effectively more than 50%, if you don't count the expenses because of the ticket systems. ($4.64M, so 62.5%) Also, you often break your budget down to operational vs. capital expense, so if you just look at it in terms of operational, it could be construed as even worse.

    That being said, municipalities in Maryland and PG County have been screwed over in recent years. We're required to pass our budgets so they'll take effect by July 1st ... and as you need enough time for an ordinance to take effect, it means we're passing budgets in early June ... so when the state decides to cut state police aid and highway user fees in August, after we've passed our budgets, we got screwed. It was too late to raise real estate or property taxes, and we have limited ways to raise revenue other than that ... it's basically tickets, parking meters, and whatever fees we might charge for services (in my town, parking permits for the lot we own, and that's it; oh ... and speeding tickets on county or state roads? most of the money goes to who owns the road, not to who writes the ticket)

    So, as we had no way to make up the shortfall, the state legislature last year gave municipalities the right to put up speed cameras near schools ... which didn't help my town, as we don't have any schools in our limits, but it's looking like some towns have gone hog-wild with the program. It would've been their first year, and so they had would've had to make a guess as to how much money they'd make (likely based on 'estimates' from the 'vendor'). And notice it said 'expected $2.9 million' ... it doesn't say how much they've actually made over 3/4 of the way through the fiscal year, which I'm guessing is *much* lower.

    Also, specifically regarding Forest Heights -- they've just elected what I believe was a complete replacement of their board; they've been having problems for years. Any traffic cameras would've been installed under the previous commission.

Well, let's "call a cat a cat" : it downright incitates fraud from the device provider in reporting false speed tickets, cause let's be honest, this is in all likelyhood what just happened there that was exposed.

    I just don't get how this was not set as a "pay for the device and maintenance" contract. I mean, the fishy smell is just so obvious, really. How can people let this pass ?

    Cameras are good, but under these terms are just bound to be abused.

    Actually, you are. You are accused of "exceeding the posted speed limit" or a violation of such and such law number. The speed written is simply part of the evidence that the prosecution believes suggests you are guilty of the violation. Evidence doesn't need to be exact to be considered valid. Beyond a reasonable doubt, or preponderance of the evidence, depending. If an officer paced or clocked you at 100 in a 55, and you smugly announce that you were only doing 60, you just admitted guilt of exceeding the posted speed limit.
