All movements at all site accesses shall function at levels-of-service
D or better with future without-development traffic volumes. If signalized,
the intersection(s) overall shall also function at level of service
D or better.
(b)
Improvements at study area intersections other than the proposed
site access(es), and on study roadways, shall be recommended for future
with-development traffic volumes to operate at level of service D
or better for all movements and the intersection overall, if signalized,
if the future without-development conditions function at level of
service D or better. If future without-development conditions function
at level of service E, improvements shall be identified such that
future with-development level-of-service conditions will be no worse
than level of service E. If future without-development level-of-service
conditions are F, future with-development level-of-service-F conditions
shall have no greater volume/capacity ratios and delays than future
without-development conditions.
(c)
The description of improvements shall describe their location,
nature, and schedule, as well as the party responsible for the improvements.
The listing of recommended improvements shall include improvements
both internal and external to the site, as appropriate.
(d)
The development shall be minimally responsible for within, at,
or adjacent to its site required for safe and efficient access to
the development. Development responsibility for additional improvements
off site will be determined in accordance with the provisions of the
Township's Act 209 Transportation Impact Fee Ordinance,[4] and, if applicable, by PennDOT for improvements to state
highway.
(e)
All design recommendations shall be consistent with the design
requirements of Straban Township and/or the guidelines of PennDOT,
as appropriate, including the following:
[1]
Available safe stopping sight distance measurements shall be
performed for each access, and recommendations shall be provided for
any access location that does not provide sufficient sight distance
in accordance with the applicable requirements, which may include
relocation of the proposed access, specific traffic controls, provision
of separate turn lanes, roadway geometric improvements, or turning
restrictions;
[2]
The necessity for auxiliary turn lanes at each site access intersection
shall be identified based on the current design guidelines of the
Pennsylvania Department of Transportation; and
[3]
All access points and pedestrian crossings shall be examined
as to the need for, and feasibility of, installing traffic signals
or other traffic control devices, pursuant to the guidelines and traffic
signal warrants of PennDOT.
(8)
Future conditions with the proposed development. A description of
the adequacy of the study area roadways and intersections to accommodate
future traffic with development of the site with proposed improvements
shall be provided. The analysis shall be completed for each study
peak hour for the development completion year, and any interim years,
if development phases are proposed. The evaluation shall include the
following:
(a)
Daily and peak-hour traffic volumes shall be projected for the
design year(s). Projected traffic volumes shall be calculated by adding
the assigned development trip generation to the future traffic volumes
without development on the study roadway and intersection network,
including the site access(es). Figures shall be provided in the report
illustrating the resultant peak-hour traffic volumes with the proposed
development with proposed improvements, including all turning movements.
(b)
A volume/capacity analysis based on future with-development
traffic volumes with proposed improvements shall be performed during
the peak highway and development hours for all study roadways and
intersections, including the site access(es). The level-of-service
results shall be presented graphically.
(c)
A queuing analysis (maximum queues) shall be performed during
the peak highway and development hours for each study intersection,
including the site access(es). The results of the queuing analysis
shall be presented graphically, and the available storage lengths
for all existing and proposed intersection approach lanes shall be
identified to determine the adequacy of these facilities to accommodate
the anticipated future vehicular traffic queues.
(9)
Conclusions and recommendations. This last report section shall include
a matrix comparing levels of service on each study roadway, site access
intersection, and other study intersection, if appropriate, for existing
conditions, future conditions without development, and future conditions
with development with improvements. If the development is to be phased,
all interim future conditions should be summarized. A summary of all
recommended improvements should also be provided, including responsibility
for each. Appropriate summaries should be provided indicating that
all future vehicular queues can be provided within existing intersection
approach lane limits or with the future improvements to be provided
by the applicant or others.
