(4) Traffic impact report.
(a)
When required.
[1]
A traffic impact report shall be submitted for
projects that generate greater than 500 new, average, weekday vehicle
trips (total of inbound and outbound), or 50 or more peak hour trips.
[2]
In addition to the above, the Board of Supervisors
may require a traffic impact report when, in its opinion, the following
conditions exist:
[a] Current traffic problems in the
local area (e.g., high accident location, confusing intersection,
congested intersection); or
[b] The questionable capability of
the existing road system to handle increased traffic.
[3]
The traffic impact report shall be prepared
in accordance with PennDOT Publications 201 and 282, ITE's Recommended
Practice "Traffic Access and Impact Studies for Site Development"
and shall conform to the following.
[4]
At the request of the applicant, the Township
may approve a waiver of the traffic impact report and accept either
a specific capacity improvement or contribution to the Township of
a fee in lieu of a capacity improvement to be made at a future date.
(b)
Area of traffic impact report. The traffic impact
report area shall be based on the characteristics of the surrounding
area. The intersections to be included in the report shall be adjacent
to the site or have direct impact upon the access to the site. The
intersections shall be mutually agreed upon by the Board of Supervisors,
with the advice of the Township Engineer and the traffic engineer
preparing the report. The Board of Supervisors shall resolve any disputes
between the Township Engineer and the traffic engineer.
(c)
Preparation by transportation engineer required.
Traffic impact reports shall be prepared by a professional engineer
registered in Pennsylvania with specific training in traffic and transportation
engineering, at least four years' experience related to preparing
traffic reports for existing or proposed developments and sufficient
prior traffic study experience to qualify the engineer to render any
opinions and recommendations in the study.
(d)
Horizon year. The traffic forecasts shall be
prepared for the anticipated opening year of the development, assuming
full buildout and occupancy. The buildout year shall be referred to
as the horizon year in the remainder of this chapter, and shall be
a minimum of 10 years.
(e)
Traffic data, projections and analysis periods.
[1]
Traffic data used in the report shall not be
more than one year old.
[2]
Estimates of non-site traffic shall be made,
and will consist of traffic generated by all other developments within
the study area for which preliminary and/or final plans have been
approved and traffic from background traffic growth in and around
the study area. Non-site traffic may be estimated using the "build-up"
technique, or, by way of area transportation plan data or modeled
volumes. Background growth compounded annually shall be established
using trends or growth rates from PennDOT and the Lancaster County
Planning Commission.
[3]
Analyses shall be conducted for the a.m. and
p.m. peak hour periods. If the study area includes an intersection
on an arterial roadway, or if the proposed development includes retail
related uses, then the Saturday peak hour period shall be analyzed.
Where the peak hour of the generator does not coincide with the peak
hour of the adjacent street, then the peak hour of the generator shall
also be analyzed.
(f)
Trip generation rates required.
[1]
The traffic impact report shall include a table
showing the categories and quantities of land uses, with the corresponding
trip generation rates or equations (with justification for selection
of one or the other), and resulting number of trips. The trip generation
rates used must be either from the latest edition of Trip Generation
by ITE, or from a local study of corresponding land uses and quantities.
All sources must be referenced in the report. The anticipated types
and volumes of truck traffic using the site shall be identified.
[2]
The methodology for determining trip generations
shall be mutually agreed upon by the Board of Supervisors, with the
advice of the Township Engineer and the traffic engineer preparing
the report. The Board of Supervisors shall resolve any disputes between
the Township Engineer and the traffic engineer.
(g)
Consideration of pass-by trips. If pass-by trips
or shared trips are a major consideration for the land use in question,
studies and interviews at similar land uses must be conducted or referenced.
(h)
Rate sums. Any significant difference between
the sums of single-use rates and proposed mixed-use estimates must
be justified in the report.
(i)
Explanations required. The reasoning and data
used in developing a trip generation rate for special/unusual generators
must be justified and explained in the report.
(j)
Definition of influence area.
[1]
Prior to trip distribution of site-generated
trips, an influence area must be defined which contains 80% or more
of the trip ends that will be attracted to the development. A market
study can be used to establish the limits of an influence area, if
available. If no market study is available, an influence area should
be estimated based on a reasonable documented estimate. The influence
area can also be based on a reasonable maximum convenient travel time
to the site, or delineating area boundaries based on locations of
competing developments.
[2]
Other methods, such as using trip data from
an existing development with similar characteristics, or using an
existing origin-destination survey of trips within the area, can be
used in place of the influence area to delineate the boundaries of
the impact.
(k)
Estimates of trip distribution required.
[1]
Trip distribution can be estimated using any
one of the following three methods:
[2]
The methodology for determining trip distribution
shall be mutually agreed upon by the Board of Supervisors, with the
advice of the Township Engineer and the traffic engineer preparing
the report. The Board of Supervisors shall resolve any disputes between
the Township Engineer and the traffic engineer.
[3]
Whichever method is used, trip distribution
must be estimated and analyzed for the horizon year. A multi-use development
may require more than one distribution and coinciding assignment for
each phase (e.g., residential and retail phases on the same site).
Consideration must also be given to whether inbound and outbound trips
will have similar distributions.
(l)
Trip assignments.
[1]
Assignments must be made considering logical
routings, available roadway capacities, left turns at critical intersections,
and projected (and perceived) minimum travel times. In addition, multiple
paths should often be assigned between origins and destinations to
achieve realistic estimates, rather than assigning all of the trips
to the route with the shortest travel time. The assignments must be
carried through the external site access points and, in large projects
(those producing 500 or more additional peak direction trips to or
from the site during the development's peak hour), through the internal
roadways. When the site has more than one access driveway, logical
routing and possibly multiple paths should be used to obtain realistic
driveway volumes. The assignment should reflect conditions at the
time of the analysis. Assignments can be accomplished either manually
or with applicable computer models.
[2]
The methodology for determining trip assignments
shall be mutually agreed upon by the Board of Supervisors, with the
advice of the Township Engineer and the traffic engineer preparing
the report. The Board of Supervisors shall resolve any disputes between
the Township Engineer and the traffic engineer.
[3]
If a thorough analysis is required to account
for pass-by trips, the following procedures should be used:
[a] Determine the percentage of pass-by
trips in the total trips generated.
[b] Estimate a trip distribution for
the pass-by trips.
[c] Perform two separate trip assignments,
based on the new and pass-by trip distributions.
[d] Combine the pass-by and new trip
assignment.
[4]
Upon completion of the initial site traffic
assignment, the results should be reviewed to see if the volumes appear
logical, given characteristics of the road system and trip distribution.
Adjustments should be made if the initial results do not appear to
be logical or reasonable.
(m)
Total traffic impacts. Traffic estimates for
any site with current traffic activity must reflect not only new traffic
associated with the site's redevelopment, but also the trips subtracted
from the traffic stream because of the removal of a land use. The
traffic impact report should clearly depict the total traffic estimate
and its components.
(n)
Analysis.
[1]
Traffic analyses shall be completed for the
existing conditions and opening day/buildout year and horizon year,
both without and with development. Analyses may consider proposed
roadway improvements only if said improvements have funding committed
by the sponsoring agency (i.e., for state projects, this would include
only those projects in the current TIP).
[2]
Capacity analysis must be performed at each
of the major street and project site access intersection locations
(signalized and unsignalized) within the report area. In addition,
analyses must be completed for roadway segments deemed sensitive to
site traffic within the report area. These may include such segments
as weaving sections, ramps, internal site roadways, parking facility
access points, and reservoirs for vehicles queuing off-site and on-site.
Other locations may be deemed appropriate depending on the situation.
[3]
The recommended level of service analysis procedures
detailed in the most recent edition of the Highway Capacity Manual
must be followed. The Township considers the overall level of service
ratings A, B and C to be acceptable; level of service ratings D, E
and F are considered to be unacceptable.
[4]
The operational analyses in the Highway Capacity
Manual should be used for analyzing existing conditions, traffic impacts,
access requirements, or other future conditions for which traffic,
geometric and control parameters can be established.
[5]
Capacity analysis, as defined by the Highway
Capacity Manual, is a set of procedures used to estimate the traffic-carrying
ability of a facility over a range of defined operational conditions.
The capacity analysis uses levels of service (LOS) to describe the
operational conditions. A brief description of the various levels
of service is presented below. Levels of service are assigned letter
designations "A" to "F," with "A" being the most desirable operating
conditions. A level of service "D" is generally acceptable according
to the Institute of Transportation Engineers standards. At an unsignalized
intersection, the level of service measures the ability for turning
traffic to find gaps in the major street traffic flow that permit
the successful completion for the desired turning movement. For signalized
intersections, the level of service measures the total control delay
time per vehicle. Also, the volume-to-capacity ratio relates to the
level of service at these facilities. This ratio relates the peak
hour traffic volumes for a facility to a theoretical maximum traffic
volume that the facility can carry.
[a] Level of service A: A condition
of free flow with low traffic density and high maneuverability within
the traffic stream. No vehicle waits longer than one signal indication.
[b] Level of service B: Stable flow
of traffic with negligible impact from other vehicles in the traffic
stream. On a rare occasion, drivers wait through more than one signal
indication.
[c] Level of service C: Still in the
zone of stable flow, but ability to select operating speed and maneuverability
is restricted. Intermittently, drivers must wait through more than
one signal indication and backups may develop behind left-turning
vehicles.
[d] Level of service D: Approaching
instability; drivers are restricted in their freedom to change lanes.
Delay of approaching vehicles may be substantial during peak hours.
[e] Level of service E: Traffic volumes
are near or at capacity on the arterial. Long queues of vehicles may
create lengthy delays, especially for left-turning vehicles.
[f] Level of service F: Congested conditions
of forced traffic flow where travel is slowed by stop and go conditions.
Queued backups from locations downstream restrict or prevent movement
of vehicles out of the approach, creating a storage area during part
of all of the peak hour.
