Are You a "Lineupper" or a "Sidezoomer?"

I'm usually a "sidezoomer."

I actually bought a four wheel drive car partly because I realized it would be better for taking onto shoulders and gravel during aggressive maneuvers in slow traffic.

It's times like these where we must remember the cardinal rule in race driving: "Use all the track."

I'm a sidezoomer stopper. If I see a sidezoomer coming up from behind, I try to position myself so that he has to wait and merge where he would have been if he had just lined up.

It's because of dopes like you that I got the four wheel drive car.

Zoomer stopper, if at all possible. Have seen too many accidents (and at one point was a first responder), one involving a small kid aged 5.

It's also the zoomers who make the line slower for everybody because they clog the merge point.

I'm also a sidezoomer stopper - I think that sidezoomers are out of control bastards who are going to kill somebody. The best sidezoomer stoppers are semitrailors and cops.

Ahh, but a lot of those zoomers exceed the speed limit, which is often reduced in those areas, which can then result in a reckless charge.

There are also laws forbidding passing on the right, or left/right shoulders if there is no traffic obstructions (e. g. an accident).

I did a classic zoomer stopper once, I literally did it for miles, with an 18-wheeler on my left, and the shoulders totally obstructed, due to road construction barriers on either side. In fact I made it into a FIFO queue, where I'd occasionally move up in the right hand lane but still leaving all that forward space available for forward left/right lane maneuvers, than shadow a right hand vehicle (usually a large 18-wheeler), or stop completely, making the left lane move slower or not at all relative to the right lane, and letting people who had queued (properly) in the right lane pass me in the right lane. Making sure that any zoomers that had tried their zooming trick did not pass me, that rearview mirror was most useful (in my elevated 4WD truck that I owned at the time) for maintaining queueing order. Those who did line up properly were allowed to pass, those that did not queue up properly were made to go slower than the entire queue (e. g. FILO) on average.

Learned this trick by watching two 18-wheelers do the exact same strategy once, bringing order to chaos, by forcing a FIFO queue, you can even leave a gap of several feet between two abreast vehicles, essentially blocking driving access to either shoulder, motorcycles or those willing to go off road (down steep embankments usually) could still get by, but these are few and far between for the majority of traffic goers.

And boy did I piss off that zoomer immediately behind me, gave him the two handed middle finger salute. once we passed the blockage point, and loved every minute of their frustration too. Also I got a wink and a nod from many of the truckers.

Teamwork. Wait your turn sucker.

How is someone going to know that somebody else is a stopper? The whole world knows who the zoomer is.

The Zoomer... at theaters everywhere.

I have seen people try to pass cops on the shoulder, and get pulled over and ticketed in NC. Google search indicates that it is illegal in California, probably in other states also.

I once got a ticket in high school for passing on the right. It was $125 bucks.

Sicne then, I really haven't done it again.

I'm following the same rulez as the zoomers are, traffic is virtually stopped in the right hand lane, I can match the speed of the ongoing traffic as long as I obey the posted maximum speed limit, and any other speed limits imposed in these areas. Once a single car is behind me I am not obstructing traffic, since the obstruction already exists to begin with. So that if someone else tries pass the slower moving right lane traffic, a vehicle in the left hand lane has every right to travel at the same speed as the rest of the obstructed traffic, as both lanes are progressing at the exact same speed.

I stay in my designated lane as outlined by the lane markers, I don't drift into oncoming traffic, now if they don't want to obey the rulez of the road and off road it more power to them. Like i already stated though there wasn't enough room to physically pass as barriers were in place. Now who's the aggressive driver? Someone who sees the signs, and sees the slower moving traffic in all lanes, and still decides to attempt to drive over another vehicles? I don't think so.

Another thing I do all the time in these situations, I never let anyone cut into my lane, I'm basically bumper to bumper, when the traffic is progressing at let's say less than 10 MPH. They basically have to hit me in an attempt to cut in. Sorry Charlie, you didn't wait your turn. I would hope that most law abiding citizens would adopt the same strategies, this would figuratively and literally stop the zoomers. Get in line and wait your turn, it's called a single queue. Go figure.

Also note that if everyone did obey the traffic signs the flow of traffic past the obstruction would be at it's most efficient, as no one is switching lanes, cutting in, or moving out of the designated lane(s) which has been proven over and over again. I did take a Highway Engineering course long ago, the traffic has to squirts past the obstruction, and then in front of them lies an almost unoccupied road. In a word, queue throughput is dramatically diminished due to zooming cutters, that's overly aggressive driving, and unsafe to boot, someone else has to stop while they let you in. An interleaved queue is grossly inefficient, as the exercise of interleaving, reduces the queue's throughput due to slower navigation through the interleaving section(s).

Case closed on that one. \

In closing I obey all the rulez of the road. \

So you can try to screw up traffic even when conditions are slippery?

Oh snap!

Ok, so I just now read the article you posted, and it says pretty much exactly what I said about an interleaving queue. Note that humans are not ants, note also that humans are not geese, but more on that one later.

I'm a perfectionist, and I'm quite sure that all drivers are not equally aware of the same things and behaviors as ants or geese, human nature dictates that not all will be equally adept at using proper queueing strategies, e. g. sparse interleaving at the rate of throughput of the choke point. Also note that the queue isn't static in length, but varies according to the differences between the mean speed of the inbound and outbound vehicles, it shrinks and grows, based on the outgoing queue speed and volume of incoming traffic.

The basic principle is to maintain an orderly and efficient queue, ants understand this instinctually, humans of much larger brain capacity mostly do not.

Now the geese example, geese fly and turn by observing the leader of the vee formation, not the goose immediately in front of them, for if they did react to the goose in front of then the vee would spiral out of control an the trailers must account for the number of lags caused by all the geese in the formation in front of them, The speed and centripetal force of the turn, means that a following the goose in front of you stratagy will not maintain the formation.

How does this apply to humans, you ask?

Well think of a red light, I'm twenty cars back, but we all see the light turn green at the same time. Now I know that if all the drivers in front of me were geese we would all move forward immediately accelerating at the same exact ramping speed. Thus, if we were geese, which for obvious reasons we're not, then the throughput through that traffic light would be maximized.

But since we are not guess, and none of you are well trained drivers, with excellent spatial skillz like I have, this perfect throughput never happens. That's because of human behavioral patterns and a lack of adequate reaction, spatial skillz, and rigorous training. We wait for the vehicle immediately in front of us to move first before we attempt to move, because we don't know how skilled and trained those drivers are, it's called a chain reaction, and is never as efficient as say cyclists drafting, it's a innate learned skill, which other species develop to a much higher level than almost all humans, because the innate skill benefits the whole.

Humans are self centered and never think in coordinated group behaviors, they do not innately trust that all others in the group will exhibit the exact, or very similar behaviors. They are not schooled properly in group behaviors, and there is always a social or mentally retarded individual that the society tolerates through artificial means, they will always be the one to slow down the entire process, they will always screw up the whole thing to begin with.

I think of geese, every time I'm at a red light, behind several cars, and think what a bunch of stupid and uncoordinated individuals, can't you see the light just turned green. Yup, but they don't have the sense or skillz, to navigate the red light properly. D'oh!

Sidezoomer to a reasonable opening in traffic. There's no reason not to use as much road as is available before merging since at most traffic densities this comes up in the speed at the merge point is low anyway. I also always let one car in at the merge point if I happened to have lined up earlier.

Blocking folks from using the available road seems childish. Regardless of queing theory, traffic engineers disagree to the point where they post signs that say "Use all available lanes until merge" in some states.

Efficient queing is all very well but when traffic density increases too much you can't zipper merge at speed anyway. Roads are clogged and you get slowdowns even without bottlenecks, construction or accidents.

I only use the shoulder if I'm within very close visual range of my exit. Mostly because it's a tad too tantilizing not to do so if there's no danger to anyone else and I'll be one less car clogging up the road.

Eh, super aggressive vigilantes are as big a problem as super agressive sidezoomers.

I suggested a strategy employed by truckers, it does establish higher throughput, as there are no longer as many lane changes as the number of vehicles is fixed and ever diminishing in front of the zoomer speed bump. Heck are you old enough to remember the 55 MPH speed limit? Cop cars use to drive abreast to enforce the speed limit.

No one is getting in the way of an orderly and more efficient choke point, in fact just the opposite. I don't obstruct traffic, I go at the speed of the slowest moving lane, whichever lane I happen to be in, and I stay in that lane, it's 12 feet wide, I have a right to use it just as anyone else does, as long as I'm not moving laterally to purposefully stop an oncoming vehicle, which I have never have done.

I'd even consider it altruistic, since I've given up my ability to jump to the front of the line.

Yes. So?

Given that truckers are not traffic engineers and there ARE signs that DO say use all lanes until the merge point I think that you'd have to address that first before you can assert that blocking the empty lane establishes a higher throughput in all traffic situations.

Blocking access to exits is one negative effect of vigilantes like yourself. It's one thing when traffic is slow and you can't get off the road. It's another when it's because some pompous asshat is blocking the way.


Yes, it's not illegal to block a lane any more than it is illegal to side zoom. But it is no more polite or moral to do so and hardly altruistic. It's simply imposing your worldview on others. Saying that's altruisitic simply indicates you're an arrogant jerk.

Do you drive at the speed limit in the fast lane as well? Push every button on an elevator because it would be healthier to take the stairs?

Please. Do what you want but don't claim altruism for self serving behavior.

Actually, you screw up traffic by getting in the way. Not only is this common sense, but the research Shawn cites seems to agree. Water flowing through a pipe doesn't line up. It's optimal for drivers to distribute their cars in as much road as possible. You prevent that. You are a control freak. Let go.

It's called the Golden Rule. I'll keep on doing as I please because I know more than you do in this matter. Sorry for the reality check. Now bug off.

Human nature being what it is a single queue is the most efficient strategy in terms of throughput.

Oh and I'm a Research Hydraulic Engineer, water is not an animate creature. Water does not brake in and of itself. Water losses energy in a confined abrupt constriction, water flowing in a single sized pipe or open channel flow has the minimal head loss. Thus a single lane of evenly and unchanging traffic is the de facto most efficient means of moving water, err traffic. So there. It's called the Bernoulli Energy Equation. Therefore, in mathematical terms this can be easily proven, since the least energy lost (or in this case net flow loss) results in the greatest amount of flow.
. No getting around the basic laws of physics, that's for sure.

But perhaps you would like to discuss RANS modeling? Or the shallow to intermediate depth Boussinesq Equation. 1D, 2D, or 3D, take your pick, I'm game.

I think your job got in the way of clear thinking this time; too much time spend thinking one way, and it's easy to overlook the simple answer. What I'm saying is that these traffic problem are not straight flow. No, they are episodes of mergers, lane endings, blocked lanes, etc. At some point the cars need to merge, but it's not going to speed up traffic if everyone did this earlier. It will slow it down, in fact, because the unused part of the road could have accommodated cars. No amount of hydraulic modeling will give you this answer because water doesn't leave gaps.

Wrongo bucko. Ever hear of circulation cells? Or reverse circulation? Think about not moving forward at all or at a very slow net rate of forward movement in these virtually trapped areas. This happens all the time in real flow fields such as for instance river flows which are modeled as 1D flow fields which is the exact same situation we are dealing with here.

My point exactly. Merging or interleaved traffic will never "flow" as efficiently as a fully coordinated flow field as occurs in nature. The flow inherently stagnates or backs up when the players are not a highly coordinated set of choreographed players. Then we get into what are conventionally called flow training structures. Something traffic engineers have yet to consider seriously. They're called flow straighteners and are sets of structures perpendicular to the flow field, and we know they work, otherwise we wouldn't use them in the first place. D'oh! Hydraulic engineers have been using them for hundreds of years to keep entrance channels clear for navigation purposes to maintain channel orientation and to insure that the channel does not become blocked due to trapped sedimentary buildup. In essence the trained flow moves through the coordinated set of obstructions much more efficiently than would otherwise occur if left to Mother Nature. The Mississippi River South & Southwest Pass into the GOM are excellent examples, from a purely hydraulic perspective.

But at this point I don't really care what happens, so go ahead fill up all all lanes with stagnant traffic, human nature being what it is, I'll always be able to cut in on others, but others will never be able to cut in on me. I have a perfect track record in that regard.

Oh, and I'm actually starting to cotton to the whole vigilante schtick. Creating artificial flow constrictions elsewhere behind the most forward point of blockage is a Good Thing™ simply because these artificial boundary conditions constrain the forward flow field to a fixed but ever decreasing mass of vehicles, via the continuity equation. Kind of like Tetris but with a lid on top and a hole on the bottom. Neat. Now I know which individual blocks will get out first, those being the ones more inline with the exit hole in keeping with the dictum of cutting in yourself, but not allowing others to cut in on you. It's actually an excellent gaming strategy, since all gaming players or blocks are not equally aware a priori.

Side zoomers are selfish. Everyone else has to wait in line, but you don't? What makes you special? You're racing ahead to cut in front of people that are already waiting. Do you do that at the movies or when grocery shopping?

I don't block the lane to stop them from zooming, but I sure as heck will go out of my way to make sure they have no space to merge.
