As summarized in Table 2, most of the unsignalized intersections have turning
movements operating at good levels of service (LOS C or better) during the peak
hours. However, three intersections have one or more side street approaches
operating at LOS D or worse. The Quincy Street stop-controlled approach to East
Hollis Street operates at LOS D during the weekday evening peak hour. The Vine
Street stop-controlled northbound approach to West Hollis Street operates at LOS D
during the weekday evening peak hour. Finally, the Chestnut Street intersection
with Factory Street (which is part of the Walnut Street Oval) operates at LOS F
during the weekday evening. All of these poor levels of service occur on the minor
legs of unsignalized intersections where long delays are a result of the high through
volumes on the major intersection legs, making it challenging for side street
motorists to enter onto major roadways.
