The overall delay at the Main Street/Park Street/ Water Street intersection shows a
modest improvement with the conversion to two-way operations. This is primarily
due to the shift in vehicle demand from Water Street to Factory Street.

The portion of West Pearl Street from Walnut Street to Main Street and East Pearl
Street from Main Street to Temple Street could be transitioned from existing 1-way
westbound to 2-way traffic flow under the East and West Pearl Street 1-way to 2-way
alternative. This alternative is illustrated in Figure 19.

This conversion to two-way flow along the entire length of the study area would be
relatively complex due to the varying existing cross section of the pavement width.
The narrowest section is located on East Pearl Street near the Temple Street
intersection where the road is only 28 feet wide. The widest section of the roadway is
on East Pearl Street between Main Street and Spring Street where the cross section is
38 feet wide. The constraints of the existing pavement width would limit the choice
of what new roadway geometry to include; travel lanes in each direction, on-street
parking and bike lanes. Traffic control device modifications would be necessary at
Temple Street/East Pearl Street Main Street/East Pearl Street/West Pearl Street and
West Pearl Street /Walnut Street. Additional minor street intersections would also
need some modifications. These traffic control device modifications include the
following:
> Removal of one-way street and prohibited turn signage at multiple intersections
including Walnut Street/ West Pearl Street, Elm Street /West Pearl Street, East
Pearl Street/Spring Street, East Pearl Street/Cottage Street, East Pearl
Street/Quincy Street, East Pearl Street/Holmes Street, East Pearl Street/Mason
Street, East Pearl Street/White Avenue, and East Pearl Street/Temple
Street /South Street.
» Modification of traffic signal heads on the existing west bound approach at East
Pearl Street's intersection with Main Street.
» Installation of traffic signal heads for the east bound approach at West Pearl
Street’s intersection with Main Street.
