The worst of Edgartown’s traffic problems is still months away, but a group of Northeastern University students are spending the off-season looking for a solution.

For the second year in a row, transportation students participating in professor Daniel Dulaski’s senior capstone project are facing off against a worthy opponent: Edgartown’s seasonally-congested streets and traffic patterns. Their solutions include narrowing traffic lanes and adding a shoulder, turning Cooke street into a bike-only street, and changing traffic patterns around the congested triangle area.

The five students — Salina Martin, Christopher Howard, Sarah Keenan, Douglas Halpert and Jeffrey Eisenhaur — traveled to the Vineyard for the first time Friday to present their proposals for the Upper Main street area, which includes the jail, Stop & Shop and the infamous triangle intersection between Edgartown-Vineyard Haven Road, Main street, and Beach Road that often produces backups in the summer months. As part of the project, the students take on real-world traffic problems and pose solutions. Other student groups this year are working on problems in Boston, Medway and North Attleboro. Last year, a similar group looked at lower Main street.
