This bill mandates the New Jersey Department of Transportation (DOT) to initiate a year-long study on the effectiveness of the "zipper merge method" on State roadways, particularly in areas where construction or infrastructure projects result in lane closures. The study must begin within 30 days of the bill's effective date and will assess various aspects of the zipper merge method, including a review of existing research, feasibility and potential benefits, impact on traffic safety, and necessary infrastructure modifications or signage.

If the study's findings support the implementation of the zipper merge method, the DOT is required to develop a plan for its application on affected roadways. Additionally, the department must submit a report to the Governor and the Legislature within six months of completing the study, detailing the findings and any proposed implementation plan. The bill also provides definitions for key terms, such as "zipper merge method" and "merge point," to clarify the scope of the study.
