The Michigan Department of Transportation will be the latest to try out the zipper merge system. MDOT hopes the system will help traffic move through construction areas at a faster pace.
With the current system, the delays caused by traffic jams has become almost unbearable for drivers. The zipper system is supposed to encourage drivers take turns merging, which should get everyone to their destination much quicker.
In Minnesota the zipper system is used and has made a big impact on traffic. MnDOT has released the following video showing off the zipper system and its effectiveness.
In addition to finding ways to keep traffic flowing through construction zones, states also need to make sure signage is clear and up to date.
