Figure 13: Walnut Street Oval Grid Pattern Circulation Alternative
Reconfiguring the Oval into a grid pattern would closely follow the existing roadway
layout as shown in Figure 13 while maintaining the building located in the center of
the Oval. This would increase circulation between the western portions of the study
area with Main Street particularly if combined with traffic flow modifications along
West Pearl Street and Factory Street. This alternative would provide an important
connection from the Broad Street Parkway entering the Mill Yard along Central
Street, onto West Pearl Street and onto Main Street. However each intersection
within the grid would require traffic control modifications. A combination of stop
sign controlled and/or traffic signal controlled intersections may be required
depending on the modified traffic volume patterns.
Reconfiguring the Walnut Street Oval into a single consolidated intersection at the
southerly end of the existing Oval (near West Pearl Street) could be controlled by
either a traffic signal or a roundabout. The traffic signal and roundabout
configurations are depicted in Figure 14.
