ODOT: The Cars Zooming to the Orange Barrels Before Merging Are Doing It Right

Author/Presenter: Murphy, Chad
Abstract:

The Ohio Department of Transportation (ODOT) endorses the zipper merge technique to reduce traffic congestion and delays during lane closures on interstates. Despite common frustration among drivers who merge early, ODOT explains that the zipper merge, where drivers stay in their lanes until the merge point and then alternate merging, can decrease congestion by 40% and shorten backups by one-third of a mile. This method, likened to the interlocking of a zipper, maximizes road space and keeps traffic flowing more efficiently. While some drivers remain skeptical or resistant, others recognize the potential benefits and suggest broader education and signage to promote its adoption. Reactions from the public highlight varying degrees of acceptance and emphasize the need for better driver awareness and cooperation.
