A Transportation Plan for the Greenleaf Terrace Neighborhood

Figure 2: Criteria for determining severity of through traffic problems.
Existing conditions that fall between the two curves will be considered moderate and subject to
the application of appropriate traffic calming measures if another type of traffic problem also
exists, (i.e., speeding). Streets that portray combinations of volume/through traffic percentages
above the higher curve will be considered intolerable to the extent required to warrant the
application of traffic calming measures to reduce the volume of through traffic.
Speeding Analysis: Speed limits have been posted along most of Charlottesville’s residential
streets. Posted limits of 25 and 30 MPH are fairly common. Past experience has shown that
some speeding will likely occur in most, if not all situations. Accepted procedures for determining
the safe operating speed along an unposted street includes measurement of prevailing speeds,
and considering posting a limit at or near the 85 th percentile speed.
