Zippity Doo Dah

 

In a perfect world where people are always well-behaved and courteous and the bluebird of happiness accompanies them throughout their day, the zipper merge would work as harmoniously as traffic engineers envision it working. In practice, the zipper merge rarely works well, and instead it becomes a place where jerks can take advantage of the polite behavior of others in order to cut in line. Everyone who drives is familiar with the traffic setup, but not everyone may be acquainted with the term “zipper merge”.

 

A zipper merge refers to the area of road where one or more lanes end, and all traffic must move into the remaining open lane or lanes, such as in a construction zone. A similar situation presents itself where one lane of a road becomes an exit, with warning signs posted that the lane is for exiting only. Traffic engineers refer to these areas as zipper merges because ideally that is how they want drivers to conduct themselves where a lane closes down or where an exit lane is about to leave the main roadway. Like a closing zipper, cars in adjacent lanes should politely alternate merging together into the one open lane, making use of the closing lane as much as possible.

Construction Barrels (14173532670)
Every driver recognizes these orange barrels as the lane markers in road construction zones, but not every driver reacts to them the same way, much as traffic engineers would like them to.

It’s a neat theory, and when it works as proposed it is a fine thing. “After you, sir.” “No, I insist, madam, you go first.” “Ah, very well, I shall do so then, and a fine day to you, sir.” “My pleasure, madam.” And a tip of the hat to you, too. Usually, however, most drivers who see the warning signs about a lane closure will move over to the through lane early, queuing up. The zipper merge happens in a sense, but farther back from the closure than engineers envisioned it. This polite behavior by most drivers is admirable because it invokes the manners ingrained in many people from early in life, but it has the effect of leaving a stretch of open road in the closing lane, and that is a temptation for jerks.

Not all drivers who take advantage of the open lane are jerks in their own eyes, because it is as hard for a jerk to recognize his own jerky behavior as it is for a fish to understand it is swimming in water. There are many rationalizations available to jerks, after all, the most prominent one provided by the traffic engineers who designed this scenario. The jerk reasons as he zips past everyone waiting patiently in line and then cuts in at the front “We’re supposed to use all of the closing lane up until the very end, but the idiot sheep lined up over there don’t understand that!” he would be more hesitant to try the same maneuver in a long store checkout line, but here in this situation traffic engineers have by default endorsed predatory driving, and therefore the jerk sees it as okay.

The exit lane situation is designed into the roadway, rather than being an ad hoc situation due to construction, but it promotes the same kind of selfish behavior. A multiple lane road in town loses one lane to an exit, and at times when the traffic is heavy there may be a long line of slowly moving cars in the lane which will eventually veer off the main road. The opportunistic jerk assesses the situation and, instead of dropping into line at the back, where cars are moving slowly and obviously intend to exit, continues at speed in the lane adjacent to the exit lane until he sees his opening near the front, shortly before the exit lane leaves the road, and swoops in, as often as not using his turn signal, as if that made his shark move alright. “Hey, I’m signaling! Let me in!”

There’s not much that can safely be done about zipper merge jerk behavior other than rage against it or hope that traffic engineers get their heads out of the clouds and figure out a better way to design merge zones, one that takes into account actual human behavior in the real world. Tom and Ray Magliozzi, the auto mechanic brothers who conducted the Car Talk call-in radio program on NPR until 2012, when elder brother Tom’s failing health forced them to discontinue the show, had a caller on one show that they reran in 2015 who had a question for them about using the open lane in a zipper merge. The show was Episode 1538: “Aberrant Behavior Syndrome”, and the caller was Brian, from Kentucky, who called in at about the 11:30 mark of the show. Brian wasn’t absolutely a jerk, even if he did rationalize using the open portion of a closing lane at the expense of his fellow drivers, but Tom and Ray – especially Tom – set him straight in a most definitive and entertaining manner, and their reasoning goes beyond the misconceptions of traffic engineers and the pushiness of jerks who look out only for themselves.

What’s the Rush?

 

When a pedestrian comes to an intersection and presses the “walk” button, the pedestrian may feel frustrated that the button doesn’t seem to do anything. The pedestrian is correct. Usually, pressing the button accomplishes nothing, at least not at an intersection busy with vehicular traffic. Very early or very late in the day, when hardly anyone is around, pressing the button may interrupt the regular signal cycle. Some pedestrians know this and yet can’t resist pressing the button at all times of day. They can’t give up feeling in control. Most others aren’t aware of how the button works, or rather doesn’t work, and press it innocently expecting a favorable result. Depending on that person’s patience, or lack of it, they may feel pressing the button has some effect. Whatever the behavior of the person pressing the button, the button’s behavior doesn’t change.

 

Impatience is the modern disease. Oddly, some of the people exhibiting impatience by using their phone while walking or driving on busy city streets are impediments to other people who are in a hurry to get to their destination. Not waiting for a better moment to use their phone than being in traffic on the road, or walking on a crowded sidewalk, causes a phone user to slow down and speed up unpredictably and meander from side to side, acting not unlike a drunk. Such behavior is exasperating to others and dangerous for everyone, including the zombie phone user. The pedestrians hurrying past and around the zombie may not understand proper sidewalk etiquette themselves, often being brusque with people they feel are in their way, when sometimes those slower folks are only minding their own business at their own pace. The clashes can be especially testy at airports as people rush to make connecting flights or get through the security bottleneck.

Stay to the right when standing or walking slowly, and keep the left side clear for those wanting to pass. Pedestrian etiquette on sidewalks, the moving type or otherwise, is the same as the rules for motorists on the road. Groups of people out for a walk should not clog the sidewalk from side to side, but travel in single or double file. Teenagers and young adults, particularly males, may not understand there is such an unspoken rule, though more likely they do understand it, and they enjoy playing chicken with other pedestrians and intimidating them. That’s another subject for another day. For most reasonable people who want to do the right thing, it’s enough to politely point out the error of their ways.

In this early scene from the 1980 parody film Airplane!, the announcements over an airport public address system go from maintaining order to getting emotional. Warning: foul language.
Realizing there are other people in the world and acting according to their interests as well as your own is a big step toward curing yourself of impatient behavior if that’s something you want to improve upon. People who act with impatience are often considering only their own interests, and some are incapable of seeing beyond that. So be it. They will always be impatient, forever cutting other people off in traffic, cutting in lines either in a car or in person, pushing everyone else out of the way on public transportation or elevators, stopping unexpectedly in the middle of a busy sidewalk to take a phone call or send a text message, and mashing the “walk” button multiple times at intersections, as if their imperious command should make any difference to a senseless button. On a particularly harried day, it would be tempting to give in and be like that yourself, even if behaving like an impatient jerk is not as satisfying a release as it might seem. Being aware and looking out for the other person is a good way to stay safe, besides being good manners.
