COMMENTS
This portion of roadway is heavily used by bicyclists creating the potential for significant conflict with vehicles traveling at relatively high speeds. Additionally, the horizontal
and vertical curves in the alignment limit visibility for vehicles exiting side streets and driveways onto PVDS. The speed limit on the adjacent roadway (PVDW) is posted at
45 mph. Considering these factors and CVC Section 627, which specifies that bicyclist safety be considered in an Engineering and Traffic Survey, it is appropriate to apply a 5
mph reduction from the 85th percentile speed in order to establish a reasonable and safe speed limit.
