BROOKLYN - Jay Street is among the busiest in the borough, and one local group is trying to make it among the safest. 

Transportation Alternatives is calling for a major redesign of what it says is one of the most dysfunctional streets in the entire city because of its heavy pedestrian traffic, six bus routes, cycling lanes, and close proximity to the Manhattan and Brooklyn bridges. 

The group says a traffic overhaul is needed to deal with the congestion, as well as illegal parking and illegal U-turns. It hopes to see it become part of  Mayor Bill de Blasio's "Vision Zero" program, which aims to make streets safer for everyone citywide. 

Transportation Alternatives also reports that there have been 41 crashes involving pedestrians or bikers between 2002 and 2011.
