2019 PEP Fellow, Mike Knodler, featured in NEPR story on the use of “zipper merge” technique to relieve highway congestion

Drivers who confront lane closures or other merging situations should use the “zipper merge” technique says Mike Knodler, 2019 PEP Fellow, in a NEPR news story.  With the zipper merge, drivers use all open lanes as long as possible and then take turns at the merge point. Knodler and other traffic engineers say the zipper merge is safer and keeps traffic flowing. Story also featured in Maine Public.
