Meege when the lane ends.  But don't think you can cut into an exit by driving down an open lane that isn't part of the exit lane and cut in at the last second.

Dunno, but they should get the fark out of my way when I drive up behind them in a parking lot. I waited a full 30 seconds for this idiot to move earlier tonight before honking. He then pulls up to the light and when it turns green he just sits there. I wait ten seconds then honk again. Then this inattentive dickbag has the nerve to flip ME off.

When traffic is backed up behind you because you stopped to try and get over early you are farking over the people trying to get into the collector-distributor lane behind you. Going from WA 520 to I-405 is a prime example in my area of poor merging on one highway leading to extra congestion on the one feeding it. Stop wasting everyone's time with your "I do what I want" bullshiat and learn to zipper merge.

Those apparently rude drivers are putting more of the roadway to use and thus helping speed things along.

No, they are not. They are creating a bigger bottleneck where the lane ends. They benefit at the expense of everyone behind them. If their explanation made sense, then the way you change from four lanes to one is shut all three lanes at once rather than one at a time gradually.

"People are afraid to merge on freeways in Los Angeles. This is the first thing I hear when I come back to the city. Blair picks me up from LAX and mutters this under her breath as she drives up the onramp. She says, "People are afraid to merge on freeways in Los Angeles." Though that sentence shouldn't bother me, it stays in my mind for an uncomfortably long time. Nothing else seems to matter. Not the fact that I'm eighteen and it's December and the ride on the plane had been rough and the couple from Santa Barbara, who were sitting across from me in first class, had gotten pretty drunk. Not the mud that had splattered on the legs of my jeans, which felt kind of cold and loose, earlier that day at an airport in New Hampshire. Not the stain on the arm of the wrinkled, damp shirt I wear, a shirt which looked fresh and clean this morning. Not the tear on the neck of my gray argyle vest, which seems vaguely more eastern than before, especially next to Blair's clean tight jeans and her pale-blue shirt. All of this seems irrelevant next to that one sentence. It seems easier to hear that people are afraid to merge than "I'm pretty sure Muriel is anorexic" or the singer on the radio crying out about magnetic waves. Nothing else seems to matter to me but those ten words. Not the warm winds, which seem to propel the car down the empty asphalt freeway, or the faded smell of marijuana which still faintly permeates Blaire's car. All it comes down to is the fact that I'm a boy coming home for a month and meeting someone whom I haven't seen for four months and people are afraid to merge."

That's the stupidest, most unbelievable thing I've ever read.  Nobody flies first class from Santa Barbara to LAX.  If you could afford that (if it existed) you could just fly a charter to Burbank or somewhere similar and avoid LAX all together.

FTFA: Those apparently rude drivers are putting more of the roadway to use and thus helping speed things along, in much the same way water flows faster through a funnel than through a straw.

Damn I hate it when people maul physics. Water flows faster through a funnel because there is increased pressure and the water has someplace it can go, so it does. We are not physically pushing cars through - the amount of traffic behind you doesn't increase your speed.

The fastest way to move things is with laminar (smooth) flow. The ONLY way that can happen with people merging at the last minute is if all of the cars have plenty of space between them. That doesn't happen because the cars behind are going faster than the cars in front, so they bunch up. People trying to get in at the last minute disturb the laminar flow of traffic. Someone has to slow further/stop for that dick-weed to get in, which slows the process more, making people bunch up more and around we go on the vicious cycle thing.
 
2017-10-06 02:27:19 AM  
Stupid question that should not be overthought. Think of yourselves as cogs in a gear or a zipper. If you space out and merge before the lane ends you can all ways keep the line moving. Wait till the end and then each lane has to stop moving to let the other lane turn in.

The worst for merging is in Georgia when I lived there it seemed nobody would speed up to merge, but would actually slow down while getting on the freeway..very annoying.
 
2017-10-06 03:54:08 AM  
We (Germany) needed a law that regulates merging. You have to stay in your lane until it ends and the drivers in the other lane have to let you merge (zipper style)

It actually works better IMHO based on the decades of driving experience and the few years that we now have this law.

I have always admired the French expressway merge as practiced/perfected by rural drivers in a 50's Citroen...
Step 1. Don't look - you may drop your cigar.
Step 2. Merge - the Lord will provide.
Step 3. What air horns?
Step 4. Never exceed 40 km/h...

The main issue from the US side seems to be twofold:

1. I'm in this lane ahead of you, aka: Fark you I got mine

2. Zippering and making allowances for the merging cars isn't generally mandated by law.

What the fark is that mess? Are they serious?

Zippers don't group then spread.

Match speeds, make gaps, then offset and flow at speed.

Negative speed changes accumulate and grow as multiples in heavy traffic. The bigger the change, the slower the traffic.
 
2017-10-06 06:21:22 AM  
Zipper Merge is fine, IF both lanes are moving at the same speed and drivers in the lane to be merged into allow people to insert.

Unfortunately, those "rude drivers" speed much faster, and attempt to jam themselves in between cars too tightly packed, forcing traffic to halt while they cut people off.

It is the very same "rude drivers" who continue to use these idiotic "zipper merge" studies as justification for jamming up traffic, ignoring the part where they must not speed past the stop and got lane at 80mph and disrupt the flow at the merge point. In slowing down the merge into lane, more congestion is created, and the situation gets worse.

In theory, zipper merge works, in practice, it fails spectacularly.

Note that when a trucker or other driver pops back out into the merge-from lane, and maintains the same speed as the merge-into lane, traffic always speeds up in the merge-into lane. Assholes may not like it, but they are assholes. Fark them. Everybody on the highway just wants to get to their destination in a reasonable time.

Bad highway behavior that I see daily, and drives me nuts:

1. Idiots who brake at everything. Someone slowing down in the lane to the right? That's a brake stomp. Someone merge into your lane 20 cars ahead? That's a brake stomp. Getting within 40 car lengths of the car ahead of you in the fast lane, while 10 cars are stuck behind you? That's a brake stomp.
2. Tailgaters, who have to brake constantly then speed up, thus beginning the accordion effect.
3. Delayers. Stopped in traffic, they wait until the car ahead of them advances way too far before starting back themselves, then race ahead, thus making the accordion effect even worse.
4. Rubberneckers. If you need to look at the two cars on the side of the road, pull over and take pics, it will last longer; just get the fark out of our way.
5. Cell Phone Lane users. No, Charlene, the people behind you, bobbing and weaving and flipping you off are not the ones who are wrong. Put the damn phone away. If you aren't passing somebody (and at more than a 2mph difference), get the fark out of the fast lane.
6. Lane shifters. The morning drive isn't about how you can advance three car lengths by changing lanes ten times every mile. "Threading the needle" isn't a driving skill, it's just being an asshole and making things worse for everybody by causing Driver #1 to hit his breaks, and driver #2s to start the stop-and-go traffic.
7. Fast Lane Procrastinators, who travel the fast lane until their exit. And by that, I mean they wait until the last possible moment and shift across 3 or 4 lanes of traffic within a hundred feet of their exit, jamming up everybody in the process. Stop that. You drive the route every day, and fark things up for everybody else every day. Fark you. (I've personally seen this cause a massive pileup)
 
2017-10-06 06:40:10 AM  
Just don't drive to affect other drivers, drive to have the minimum effect on other drivers. It really is that simple.

Don't straddle two lanes to stop other drivers passing, don't sit in the overtaking lane to slow down the road, don't pull out just as a car is about to overtake to stop them getting past.

Those are on one hand illegal (in the UK at least) but also the actions of a dick, don't be a dick.

The thing with merging is that you can only do it when someone else makes a space to let you merge.  If someone makes a space early enough, take it.  But if you pass several opportunities to merge and wait until the end, then someone has to slow down THERE to let you in and that slows down everything.

We keep reading stories about the proper way for the merger to merge, and not how existing traffic should treat people that are TRYING to merge.  It's a dance, you can't get in until someone lets you in and sometimes people are assholes about it, and sometimes it's the merger who's the asshole about it.

MnDOT | Zipper Merge Traffic Camera Instructional
Youtube ZcPby71TNC0



The cars seem to be moving at the same speed, but since there are TWO lanes, and not just ONE, twice as many cars are getting through the merge: overall traffic delays are reduced. In a standard selfish American merge, that backup would be way longer and potentially impact other traffic (say, those who aren't heading to the merge point and are planning to exit before that).

There's a spot on my morning commute where two lanes merge immediately after a traffic light, and the merge lane is about 100 feet long.  The regulars know it and all line up in the left lane at the light.  So traffic in the left lane, at a red light, will be 40 cars long.  And there will be NOBODY in the right lane.

What do you do in that scenario?  Drive past the backed up traffic to the light and hope that someone lets you in immediately once the light turns green?  Or line up as car 41 and hope you make in through before the light cycles and you sit through another round of red?

I've had a 60 mile daily work commute since 1980 (30 there + 30 back), on the perpetually-under-construction Detroit highways, so I know a thing or two about lane closures and merging. Someone touched on it upthread, but the biggest issue with the zipper-type of merge is the people who are supposed to let the closing lane in hit their brakes if they see a car on their left or right trying to merge in. Once one person hits their brakes, everyone down the line does as well. Also, 50% of the people trying to merge in don't look for an insertion point until it's too late, they get to the point where the lane is closed and hit their brakes, then so does everyone in back of them. I noticed it getting way worse as manual transmissions in personal cars went away, as people use their brakes instead of downshifting to try and match speeds.
 
2017-10-06 07:43:19 AM  
There's a spot near my house that has two lanes at a stop light.  Not far on the other side of the stop light it drops down to one lane.

Even though all the signs at the light say to use two lanes to go straight, most people line up in the left lane.  I pull up in the right lane and usually get 1-2 cars in front of me rather than the 10-15 on a busy day in the left lane.

Unless the person in the left lane is being a dick, there's always a gap that I can use to merge.

Not that it ever ever happens, of course.

Chances are it will be a "white blocker" (tm) .

Test it yourself the next time you see a cortege of cars,

Chances are better than even it's white (full disclosure: I have twowhite vehicles) and better than the 23% +/- white vehicles in the total population.

That's what I do, and most mornings I wind up racing the front 2 or 3 cars who don't want to give up their position at the head of the line.

Nothing like seeing a Camry and a minivan laying patches of rubber at an intersection, jockeying for position to drive a couple of miles on a one lane, 35mph road.

Have one of those by me. Never understood the huge line that forms.

Thankfully, I've got great pickup in first gear, so I usually hop into the empty lane then floor it and jump into the other.

I still feel like kind of a dick when I do, but fark it: I'm not going to get stuck at the same damned light three times in one go just because everyone is a dolt.

This shouldn't matter really   You have x number of cars to get through a 1 lane scenario.   How quickly they merge isn't what's slowing things down... the pace of the cars already IN the single lane scenario dictate how slow everyone behind goes.   And the science is ignoring the fact that plenty of people in the left lane won't let last minute guy in, and that sort of stuff slows the process rather than speeding it up.

enry: Meege when the lane ends.  But don't think you can cut into an exit by driving down an open lane that isn't part of the exit lane and cut in at the last second.


I used to do it all the time. If I look ahead and there are heavy trucks in the exit lane, I know there is going to be a gap in front of them. About once a month I had to take the long way home because there wasn't a space to pull in

Fortunately I don't have to take that damn exit anymore. It was literally 20 to 30 minute wait if you pulled into the exit lane immediately. The long way was actually quicker.

If you want to see how the zipper merge works, just go to The Lincoln Tunnel at rush hour.

5 lanes merge into 1 at full speed. Drivers leave a car length open, plus an extra 3 inches for good measure.

Even though New Yorkers are generally aggressive assholes on the road, the zipper merge works perfectly. It's like watching ballet.

If you want to see it fail, drive down the 405 into LA. 6 lanes goes down to 5 and there's a 9 mile backup.

Many people have pointed out that this only works if everyone is following the rules.  Like that is ever going to happen.  Many studies have shown that one driver can disrupt traffic flow.

I can see how it works better but it requires everyone being on the same page.  Not going to happen in certain areas where congestion is unkown.  My area, ya no one is going to be practiced up.  Congestion is 5 minutes added to a 20 mile drive maybe happening twice ayear.  Areas where it is congested, learn it.

Then factor in all the assholes on the roads.

CSB: Driving on highway when I saw the construction notice that the left lane was closed in 2 miles and everyone would have to merge right. Sure enough, people started getting in the right lane, creating a one lane backup of almost 2 miles. Meanwhile the left lane was completely empty. I got in the left lane and drove almost all the way to the merge point. As I got closer a trucker saw me coming so slid his semi over so it straddled the lanes and wouldn't let me go further, at one point making me go on the shoulder. I merged in behind him and, when the lanes split again I went to pass him. He kept jockeying to block me. Finally I was able to get past him and as I did he flipped me off.

Got revenge though by calling the highway patrol to report a truck driver that was driving recklessly and endangering other vehicles.

lucksi: We (Germany) needed a law that regulates merging. You have to stay in your lane until it ends and the drivers in the other lane have to let you merge (zipper style)

It actually works better IMHO based on the decades of driving experience and the few years that we now have this law.


I have no doubt that zipper merging is more efficient, but the lack of law makes it shiatty here. On one side you have the people that won't let anyone in. In the other side you have the people that will use a lane that's about to close to literally get out of the lane they were already in and get in further up.

Speed limit signs need to be posted at the top of the on ramp for those drivers who think merging into 80 mph traffic is optimal when you're slogging along at 40 mph.

NotARocketScientist: FTFA: Those apparently rude drivers are putting more of the roadway to use and thus helping speed things along, in much the same way water flows faster through a funnel than through a straw.

Damn I hate it when people maul physics. Water flows faster through a funnel because there is increased pressure and the water has someplace it can go, so it does. We are not physically pushing cars through - the amount of traffic behind you doesn't increase your speed.

The fastest way to move things is with laminar (smooth) flow. The ONLY way that can happen with people merging at the last minute is if all of the cars have plenty of space between them. That doesn't happen because the cars behind are going faster than the cars in front, so they bunch up. People trying to get in at the last minute disturb the laminar flow of traffic. Someone has to slow further/stop for that dick-weed to get in, which slows the process more, making people bunch up more and around we go on the vicious cycle thing.


The zipper works fine in the extreme situations, but confusion arises in intermediate states.

Merging causes the cars behind to slow down, so a traveling wave of slowness ripples back upstream. If there are gaps between groups of cars, the gaps absorb the ripple. If people aren't zippering and are merging early, the traveling wave simply begins further upstream than at the end of the lane, but anger develops when people pass those who merged early.

When congestion reaches a point where both lanes are moving slowly, the zipper flows smoothly although continually emitting traveling waves upstream. But people upstream will be moving at the maximum (slow) speed in two lanes, so the overall traffic as measured before the zipper is faster than the true flow rate at the zipper.

What the zipper actually does is stop people from jumping ahead of others who already merged.
 
2017-10-06 11:09:31 AM  
If you're in the lane which is ending, and everyone in your lane ahead of you is easily merging over because traffic is moving at a steady clip, and you decide you're going to pass as many cars as you can before you merge, you're an asshole.
 
2017-10-06 11:12:17 AM  
I'll always extol the virtues of the zipper merge since it's the most efficient way, but people are assholes so it doesn't always work.

What frequently gets lost in this discussion are the situations where the merge happens on non highway/freeway roads, where it usually becomes a congested bumper to bumper crawl during peak travel times.  In those situations just drive to the front of the line and take turns at the front.  It's quite simple.

I've had one of these in my daily commute for over a decade and for the most part people make it work.  However, all I ask is don't be this guy...

2017-10-06 11:15:54 AM  
It doesn't really matter if they merge as soon as possible or use the whole lane. What farks up traffic is when people totter onto the freeway at 35 miles per hour and then only after they are in traffic, decide to accelerate to freeway speed. The ramp advisory speed of 35 does not pertain to the on-ramp, it is designed to accelerate to freeway speed before you merge and cause a 2 mile long wave of stopped cars and rear end accidents.
 
2017-10-06 11:30:11 AM  
In an ideal world there is only ONE merge point - and it really doesn't matter much where that occurs, as long as it only occurs ONCE.  The problem most people run into is when folks merge early, and then another batch of cars zooms up the open lane and jams into another merge point at the end, and that repeats itself over and over again.  Articles like this don't help - road signage might.  Fer instance, if you actually want people to only merge right at the lane closure, why are you putting up signs 1/2 mile out telling people the lane is closed?  Shouldn't the signs telling folks to merge be placed closer to the actual merge point?  Traffic will naturally slow down as it backs up so you wouldn't need to worry about cars slamming into the lane closure at 85mph.

So, did you not read the article or did you just decide that you know more about traffic patterns than the people who did the studies?


The issue is that there's two parts to the merging late thing that must be taken together for it to work better:

1) Merge late.
2) Zipper together.

That's undoubtedly the best, quickest way to improve traffic flow. What happens in the real world, though, is that people merge late and then refuse to zipper together, instead jumping ahead of the merge point so they can shove in at an even later spot.

"My gods.  The chaos.  Stop."


Then the signs need to say "Merge", not "Yield", and both (all) lanes need to operate with the same rights legally.   When the signs are saying something like "Left Lane Yield" or "Right Lane Yield" the understanding is that courtesy is optional for on lane.

Drivers that speed through an empty merging lane so they can shove themselves into traffic at the last farking second just so they can be a few car lengths ahead can EABOD. Stop rationalizing it as "maximizing the efficiency of the traffic flow" because everyone has to slow down to let you in.

Zipper merge traffic theory ignores basic human behavior. Many people go flying up the closing lane as quickly as possible, to pass as many cars as possible, then a split second turn signal, cut right in front of someone, and hit the brakes so they don't rear-end the car now in front of them, and cause a sea of brake lights because everyone now has slow down quickly because they're an arse, resulting in a pretty good traffic jam. Because it's so slow in the one lane, more impatient people keep flying up the closing lane, and cutting people off while merging, in a vicious feedback loop, causing more slowness.

Zipper merging is one of those things that works great in theory, but it doesn't take many drivers being jerks for it to turn into a monumental clusterf*ck traffic jam and cause accidents.

Once you've merged early, the people still in that lane might not have seen you so they don't know where they should merge. We're being taught to just go up to the sign and merge there. Or add a new indicator light that you flip on to tell everyone "I've merged, so don't pass me".

The first and best (and only) rule is to match the speed of the lane you are merging into as soon as feasible, so that you can claim a spot without anyone having to hit the brakes too much.  Ziping to the end of the land and trying to slam over isn't a farking "zipper merge", it's getting the beans and the frank stuck in the zipper!

LesserEvil: Zipper Merge is fine, IF both lanes are moving at the same speed and drivers in the lane to be merged into allow people to insert.

Unfortunately, those "rude drivers" speed much faster, and attempt to jam themselves in between cars too tightly packed, forcing traffic to halt while they cut people off.

It is the very same "rude drivers" who continue to use these idiotic "zipper merge" studies as justification for jamming up traffic, ignoring the part where they must not speed past the stop and got lane at 80mph and disrupt the flow at the merge point. In slowing down the merge into lane, more congestion is created, and the situation gets worse.

In theory, zipper merge works, in practice, it fails spectacularly.

Note that when a trucker or other driver pops back out into the merge-from lane, and maintains the same speed as the merge-into lane, traffic always speeds up in the merge-into lane. Assholes may not like it, but they are assholes. Fark them. Everybody on the highway just wants to get to their destination in a reasonable time.


That's what I have noticed, by me there is a zipper merge and if traffic is going at a nice speed they it works fine, one from the left, one from the right, etc. But then you get that turd in the punchbowl that has to get two cars ahead and throw off the rhythm.

Any method that has a success rate dependent on everyone using the method properly is doomed to fail.

I promise you, even with that being the rule you'll still have plenty of people waiting till the last second.

2017-10-06 10:43:36 PM  

PoweredByIrony: There's a spot on my morning commute where two lanes merge immediately after a traffic light, and the merge lane is about 100 feet long.  The regulars know it and all line up in the left lane at the light.  So traffic in the left lane, at a red light, will be 40 cars long.  And there will be NOBODY in the right lane.

What do you do in that scenario?  Drive past the backed up traffic to the light and hope that someone lets you in immediately once the light turns green?  Or line up as car 41 and hope you make in through before the light cycles and you sit through another round of red?


If there's a clear lane ahead of me and no legal reason why I have to move over, I'm staying in the lane all the way to the light. The nature of the road after the light is something I'll deal with after I pass the light. If there is merging going on right after the light, that's when I'll merge. If there was a sign before the light saying I have to merge then, that's when I'd merge before reaching the light.

Zipper merges use more available roadspace AND everyone knows exactly when to expect the next car to move in so traffic maintains a higher flow rate

The only reason there is a discrepancy in speed is because so many people merge early.  This causes one lane to slow down as it takes on more cars.  If people maintained their lanes than both lanes would move more or less at the same speed.  The assholes wouldn't be able to cut in.

This is the most ridiculous thing about people who complain about assholes (in this situation): by being "polite" and merging early, not only are they enabling the assholes, but also their collective action causes far worse trouble than the assholes themselves do.

The Charter Oak Bridge backup, the I-91S/I-691/15 ramp mess, I-84/I-91 through Hartford and Waterbury, the 95/91/34 mess in New Haven, unfinished highways (11, 9, 384, the piece of 6 in Columbia/Willimantic that was supposed to be part of 384), on ramps that become the next exit in a quarter mile, STOP SIGNS on the 200ft on ramps further south on 15 (where people tend to go 75 in a 55 zone), the traffic light in the middle of Middletown on 9... Then factor in all the assholes on the roads.


Having just moved to Stamford in the last 3 years, I second all of this. CT might have the worst drivers I've ever seen. Just last night it took me 63 minutes to go 9 miles down 95. Mostly because of lane shifting assholes who constantly jump lanes to try and find an extra second of savings. No construction, no lane closures, just incompetence leads to long backups.

WelldeadLink: Norfolking Chance:Zipper merges are fine and work in lots of places around the world. The problem is the inherent selfishness and me first attitude of Americans.

No problem. Just teach everyone that if they see an empty lane which is ending at a merge, if traffic starts to slow down then hop in that empty lane to fill it up and the zipper will set up faster. The first people in the empty lane get to jump the line.


Interesting, using the selfishness of people to enforce driving which benefits the whole road.

Maybe this tactic could be used in other areas of life.
