Definitions. As used in this part, the following terms shall have
the meanings indicated:
LEVEL OF SERVICE
As described in the Highway Capacity Manual, indicates how
well traffic moves on a particular highway facility or through a specific
intersection. There are six levels of servicing (LOS) ranging from
A through F. Level of Service "A" indicates generally free movement,
Level of Service "E" represents maximum capacity of the facility,
and Level of Service "F" indicates congestion. Level of Service "C"
is considered the design level of service, representing a stable traffic
flow and a relatively satisfactory travel speed.
MAJOR INTERSECTION
Any intersection where traffic generated by the proposal
will have a significant impact on the operation of the intersection.
The transportation engineer shall seek guidance from the Township
Engineer prior to the submission of the transportation impact study.
PUBLIC TRANSPORTATION
Transportation service for the general public provided by
a common carrier of passengers generally on a regular route basis,
by the Southeastern Pennsylvania Transportation Authority or a private
operator offering service to the public.
STUDY AREA
For proposed developments anticipated to generate 250 or
less trips in an average weekday, the study area will extend approximately
1/2 mile along the adjacent roadway in both directions from all access
points or to a major intersection along these roadways. For proposed
developments anticipated to generate more than 250 trips in an average
weekday, the study area will extend to approximately one mile along
the adjacent roadway in all directions from all access points or to
a major intersection along these roadways. The transportation engineer
shall seek guidance from the Township Engineer prior to the submission
of the transportation impact study.
TRANSPORTATION
Any mode or movement of passengers or goods while utilizing
the existing or future transportation infrastructure, including but
not limited to pedestrian, bicycle, rail (transit and freight), bus
(school and transit), vehicular and truck traffic.
TRIP GENERATION RATES
The total count of trips to and from a study site per unit
of land use as measured by parameters such as dwelling units, acres,
square footage, etc. The trip generation rates are determined by the
ITE Land Use Code most applicable or by approval by the Township Engineer
of an alternate data source.
VOLUME/CAPACITY ANALYSIS
This procedure compares a roadway or intersection approach
to its capacity (maximum number of vehicles that can pass a given
point during a given time period). The procedures described in the
most current Highway Capacity Manual, by the Transportation Research
Board, as outlined in the PennDOT Design Manual, Volume 2 or most
current, shall be followed.
WARRANTS FOR TRAFFIC SIGNAL INSTALLATION
A series of eight warrants which detail the minimum traffic
or pedestrian volume or other criteria necessary for the installation
of a traffic signal. These warrants are contained in the Manual on
Uniform Traffic Control Devices, most current edition, prepared by
the U.S. Department of Transportation, Federal Highway Administration.
