Merging may be one of this biggest stressors for drivers, especially
on busy roads. Merging into heavy traffic can be a headache because
sometimes other drivers won't let you in. And once you are in you have
to worry about other merging drivers swooping into your lane. Sometimes
drivers don't merge soon enough, or else there are those drivers that
just make it impossible for anyone else to merge because they refuse to
leave a space open.
But why does merging make us so
angry? And why can people never seem to figure it out? This article from
Edmunds.com explains the psychology of merging, and even tells you how
and when to merge without losing your cool.

Why Late Merging Ticks Us Off
Merging
is only one of a long list of driving situations that stir deep
emotions. Yet, when best-selling author Tom Vanderbilt began his
400-page book Traffic: Why We Drive the Way We Do (And What It Says
About Us), he zeroed in on merging as a universal measure of a driver's
personality. The prologue of his book is titled "Why I Became a Late
Merger (and Why You Should, Too)."
Vanderbilt suggests
that a driver's merging style reveals his personality. There's an old
cliché in driving studies," he says: "'A man drives as he lives.'" New
York Times columnist Cynthia Gorney boiled the debate down to two main
driving personalities: "lineuppers," who take their turn, and
"sidezoomers," who race to the head of the line and dart into an opening
at the last second. This is maddening to the well-behaved lineuppers.
In fact, a Minnesota Department of Transportation study revealed that 15
percent of drivers actually admitted to straddling lanes to block late
mergers in construction zones.
Gorney finds her
description of sidezoomers gets a spirited response from everyone she
questions. "When I raised [this] with my father, who is 83, he startled
me by suggesting a longer label that included more bad words than I
believe I have ever heard him use at one time." She even found a
University of Washington engineer who had his own name for the two main
merging personality types: cheaters and vigilantes.

James, a.k.a. "Dr. Driving," whose Web site has a string of articles
under the heading "The Great Merging Debate," says merging areas are
especially challenging because there are basically two styles of merging
that are often incompatible. When early mergers see the late mergers
zip by, "most drivers feel irritated, some angry and roadrageous," he
says. Trying to block them is "dangerous, illegal and begging for a
confrontation."
James sees a connection between the
different merging styles and a driver's personality. "Motorists who are
less aggressive and more accommodating tend to be early mergers," James
says. "They are more community-spirited drivers." On the other hand,
late mergers are "more aggressive and opportunistic." And they don't
necessarily think of themselves as an exclusive club, either.
"They feel that everybody can be a late merger, and if they choose not to be, it's their choice," James says.
The Case for Late Merging
When
you apply the term "sidezooming" to late merging, it conjures up all
kinds of negative images. But there is an argument for late merging:
It's a more efficient use of the road.
Highway lanes
offer a limited amount of space and, because of the volume of traffic,
that space is becoming increasingly restricted. So the question becomes
this: How can the maximum number of cars quickly move through a set
space as that space narrows? Traffic engineers sometimes equate this
situation to grains of rice flowing through a funnel. The analogy breaks
down, however, when you realize that the grains are touching and
sliding against each other as they move — we obviously don't want that
with cars. But the comparison is still relevant.
High
accident rates in construction zones triggered the Minnesota merger
study, says William Servatius, construction programs coordinator in the
Minnesota Department of Transportation's Office of Construction. He adds
that when drivers are instructed to merge at construction areas: "Many
times crashes occur due to aggressive driving, abrupt lane changes or
sudden stops."
Using speed-sensing devices that display
different messages depending on the speed of traffic, Minnesota DOT
engineers developed what they call a "zipper," which meshes cars
quickly. Signs advise drivers of the upcoming lane closure, tell them to
use both lanes up to a point and then direct them to take turns
merging. When traffic is flowing, drivers merge early to avoid unsafe
maneuvers. But when traffic is congested, motorists make full use of
both lanes. The data revealed that the change reduced traffic lines by
35 percent and also brought down "lane changing conflicts," says Craig
Mittelstadt, Minnesota DOT's work zone safety specialist.
But
most highways' merging zones don't display friendly signs that tell
drivers it's OK to merge late. And so the conflicts continue. And along
with the conflicts comes the inevitable finger-pointing (or
finger-giving, in many cases).
Kinder, Gentler Merging
The
morning after reading these merging studies, I decided to create a
third category of driver for myself. I would be neither a lineupper nor a
sidezoomer. Instead, I would be a "sidesignaler," politely cruising
along by about a quarter-mile of stopped traffic with my turn signal on,
requesting an opening. Sure enough, I reached the zipper and saw a gap
between cars. In fact, it was a huge gap. I slid into the opening and
held my breath. No blaring horns, flashing lights or angry shouts
followed my maneuver. I risked a look in the rearview mirror and saw
why. The driver was on a cell phone.
