Study
Conclusions
The benefits do not only impact Klingle Road.
The Transportation Study (Appendix D) concluded that opening Klingle
Road would provide significant transportation benefits overall.
These benefits accrue to the entire area considered in the
Transportation Study. This area includes major arteries in Cleveland
Park and Woodley Park, such as Connecticut Avenue, Porter Street,
Woodley Road, Cleveland Avenue, etc., and congested intersections such
as Connecticut and Porter.
The Berger report included a transportation study of four major
intersections in Woodley and Cleveland Parks, including one of the
busiest intersections in Cleveland Park, Connecticut Avenue and Porter
Street. Here are the transportation study conclusions:
Although most of the
intersection approaches would continue to operate with the same level of
service as under the no build condition, average vehicle delays and
volume to capacity (v/c) ratio would be significantly reduced.
Berger, page D-8.
If Klingle Road were
reopened, there would be stop delay reduction at the intersection
of Porter Street and Connecticut Avenue, thereby improving travel
speeds along Porter Street. Berger, page D-8.
The reopening of Klingle Road
will significantly impact the travel speed on
Connecticut Avenue. Berger, page D-8.
"In general, it is expected
that the overall accidents in the study area could be reduced
if Klingle Road was opened due to the diversion of traffic from the
intersection of Connecticut Avenue and Porter Street." Berger
D-10.
Within the Berger report study area, traffic
accidents overall will be reduced, traffic delays overall
will be reduced, and levels of service overall will be
improved. See Study, page D-10. These improvements will
benefit the entire study area which includes Connecticut Avenue, Porter Street, Klingle Road,
34th Street, Cleveland Avenue, Cathedral Avenue, and Garfield
Street.
Safety analyses conducted
in the study area reveal that there were approximately 69 crashes over a
3-year period. The majority of these crashes, approximately 56,
occurred at the intersection of Connecticut Avenue and Porter Street. In
general, it is expected that the overall accidents in the study area
could be reduced if Klingle Road was open due to the diversion of
traffic from the intersection of Connecticut Avenue and Porter Street.
Berger Study, D-10
Without Klingle Road: As a part of
this study, an analysis was conducted to determine various improvements
required at this intersection [Connecticut Avenue and Porter Street] for
the design year under the no build scenario to achieve an acceptable
level of traffic operation. Results of these analyses indicate
that the eastbound approach of Porter Street needs to be widened to
accommodate an additional two through lanes, while an additional through
lane is needed in the westbound direction as well. Even if these
improvements are implemented at this intersection, traffic congestion is
expected to shift to other area intersections along Porter Street.
