Zipper Merge Revisited … and Improved!

As some of you already know, I am a proponent of zipper merge. It is an easy solution to a common traffic problem based on the simple concept of taking turns — something we all learned as kids. Yet as adults, we seem to have an exceedingly difficult time adjusting to this change. A new report documents that Winnipeggers aren’t exactly embracing the idea.

Years of scrapping and clawing our way through an adulthood filled with greedy and selfish individuals has beaten the concept of taking turns from our Anterior Cingulate Cortexs. Yet I still believe it’s in all of us. Or most of us. Maybe we just need to help nudge it out of its hiding place.

Therefore I propose a minor adjustment to the design of the zipper merge. A normal zipper merge (figure A) is a standard construction merge where one lane is lost, and drivers from the open lane are expected to let drivers from the closed lane “zip” in because there is a sign telling them to do so. Sounds easy enough, but old habits die hard I guess, so let’s force the issue.

My new Version 2 of zipper merge (figure B) takes the dominant lane distinction away. Both sides lose half a lane and merge evenly into a single common lane. There is no reason for all the cars to stack into a single lane, nor is there a reason to block someone out when they try to merge. Everyone is equal!

Like any change that involves a minuscule adjustment to traffic norms, people will hyperventilate and predict chaos and carnage because “Winnipeggers are bad drivers” etc. That’s OK. We know it’s coming and we can prepare for it by plugging our ears and singing.

No conclusion can be reached based on the City of Winnipeg’s modest, half-hearted attempt at zipper merge last summer. It’s sensible and inexpensive to implement. There is no reason not to keep pushing forward with zipper merge. I can start a GoFundMe to order new signs if that helps.

Let’s ignore the naysayers and embrace innovation!

  2. Thank you!! Exactly the change I think needs to happen.

    The OLD sign indicates imminent loss of one lane, clearly indicates that the other lane is preferred. This sign is a contradiction to the signs urging drivers to ‘use both lanes’ and to ‘zipper merge’. There is no place for this sign when you are trying to encourage ( teach) zipper merging.

    Remove those old signs and put up NEW ones as shown, then use pylons to match the signs, making both lanes move to the center (figure b) as they merge.

  3. Not just a Winnipeg problem. Figure B is better than what we have now. The science behind the zipper merge assumes two (or more) cars will be going the same, constant speed. This never happens in reality.
