Definitions. As used in this section, the following terms shall have
the meanings indicated:
ACCESS
A driveway, street, median opening, or other means of passage
of vehicles between the highway and abutting property, including acceleration
and deceleration lanes and such drainage structures as may be necessary
for proper construction and maintenance thereof.
AUXILIARY LANE
The portion of the roadway adjoining the through lane that
is used for speed change, turning, storage for turning, deceleration,
acceleration, weaving, and other purposes supplementary to the through
traffic movement.
BANDWIDTH
The theoretical window of time through which a platoon of
vehicles can traverse the entire signalized system at the design speed
without stopping. The bandwidth efficiency is the ratio of the bandwidth
to the signal cycle length expressed as a percentage.
COORDINATED TRAFFIC SIGNAL SYSTEM
A series of signalized intersections that are synchronized
to provide a progressive movement of traffic in order to minimize
vehicle stops and delays.
CORNER CLEARANCE
The spacing between driveways and street intersections, which
is desirably outside of the functional area of the intersection.
CROSS ACCESS
Interconnected vehicular access between two or more contiguous
sites so that the driver need not reenter the public street system.
DRIVEWAY
Every entrance or exit used by vehicular traffic to or from
properties abutting a highway. The term includes proposed streets,
lanes, alleys, courts, and ways.
EGRESS
The exit of vehicular traffic from abutting properties to
a street
FRONTAGE ROAD
A road that runs generally parallel to a higher speed major
road, and which provides access to all abutting land uses, and without
the need for direct access for each parcel. Land uses along the frontage
road are still visible from the major road. The frontage road feeds
the higher speed major road at appropriate points of access.
FUNCTIONAL AREA
The area beyond the physical intersection of two streets
that comprises decision and maneuver distance, and the required vehicle
storage lengths.
HIGHWAYS, ROADS, or STREETS
Any highways, roads, or streets identified on the legally
adopted municipal street or highway plan or the official map that
carry vehicular traffic, together with all necessary appurtenances,
including bridges, rights-of-way and traffic control improvements.
The term shall not include the Interstate Highway System.
INGRESS
The entrance of vehicular traffic to abutting properties
from a street.
JOINT ACCESS
A shared driveway connecting two or more contiguous sites
to the public street system.
LEVEL OF SERVICE (LOS)
A qualitative measure describing the operational conditions
within a section of roadway or at an intersection that includes factors
such as speed, travel time, ability to maneuver, traffic interruptions,
delay, and driver comfort. Levels of service is described as a letter
grade system (similar to a school grading system) where delay (in
seconds) is equivalent to a certain letter grade from A through F.
LOCAL ROAD
Every public highway other than a state highway. The term
includes existing streets, lanes, alleys, courts, and ways.
OUTPARCEL
A lot that is adjacent to the roadway that interrupts the
frontage of another lot, or in the case of consolidated development(s),
it is a building site that is located adjacent to the roadway.
PREEXISTING DRIVEWAY
Permitted driveways in place at the time of the adoption
of this section that do not conform to the standards herein.
ROADWAY FUNCTIONAL CLASSIFICATION
Categorization of roadways according to the function they
serve. The arterial and major collector roads for the purpose of this
section are as follows, and as based on any future updates of the
Township's Comprehensive Plan that follow after the adoption of this
section:
(1)
Principal arterial: Pottstown Pike (PA Route 100) except within
the limits of Graphite Mine Road; Graphite Mine Road.
(2)
Minor arterial: Conestoga Road (PA Route 401).
(3)
Major collector: Pottstown Pike (PA Route 100) within the limits
of Graphite Mine Road; Little Conestoga Road; Byers Road; Fellowship
Road.
SERVICE ROAD
A road that runs generally parallel to a higher speed major
road, and which provides access to all abutting land uses, and without
the need for direct access for each parcel. The service road feeds
the higher speed major road at appropriate points of access.
STORAGE LENGTH
Lane footage needed for a right or left-turn lane to store
the maximum number of vehicles likely to accumulate during a peak
period of travel.
STREET
Includes street, avenue, boulevard, road, highway, freeway,
parkway, lane, alley, viaduct, and any other ways used or intended
to be used by vehicular traffic or pedestrians, whether private or
public.
TAPER
The widening of the roadway to allow the redirection or transition
of vehicles into or around an auxiliary lane.
TWO-WAY LEFT-TURN LANE
A continuous center lane within the median area that is used
to accommodate and separate left-turn traffic in either direction
from the through traffic.
