Requires DOT to study use of zipper merge method on State roadways.

S 3555 requires New Jersey's Department of Transportation (DOT) to conduct a year-long study on the "zipper merge" method for use on state roadways during construction or infrastructure projects that close lanes. The study must examine how alternating lane usage at merge points (where two lanes combine into one) affects traffic congestion, safety, and accident rates, while reviewing existing research from other states and identifying necessary signage or infrastructure changes. If the study finds the method effective, the DOT would then develop an implementation plan. The bill mandates a final report to the Governor and Legislature within six months of the study's completion.
