Transportation-related Definitions. As used in this section, the
following terms shall have the meanings indicated:
ALTERNATIVE TRANSPORTATION MODES
Those modes of moving people or goods that do not require
a single-occupancy motorized vehicle, generally including bicycles,
pedestrian facilities and transit systems such as buses, trains, trolleys,
etc.
CAPACITY ANALYSIS
Intersection approach capacity is the maximum rate of vehicular
flow that can pass through an intersection under prevailing roadway,
traffic, and signalization conditions. The analysis compares the actual
or projected traffic volume to the intersection capacity and results
in a volume/capacity (v/c) ratio.
HIGHWAY OCCUPANCY PERMIT (HOP)
The Pennsylvania Department of Transportation (PennDOT) regulations
governing the access and occupancy of State highway, per Title 67
PA Code 441, Access To and Occupancy of Highways by Driveways and
Local Roads. PennDOT has regulatory authority to ensure the location
and design of access driveways and local roads to state highway rights-of-way
in order to preserve safe and reasonable access. Montgomery County
(County) also has regulatory authority over certain roadways within
the County and has established criteria for HOP applications.
LEVEL OF SERVICE
Level of Service (LOS), as described in the current Transportation
Research Board's Highway Capacity Manual, is a qualitative measure
of the operational conditions within a traffic stream and their perceptions
by motorists. Six levels of service (A through F) are defined for
each type of facility, with LOS "A" representing the least congested
operating conditions and LOS "F" representing a breakdown in operating
conditions. Levels of service are defined in terms of average delay
per vehicle for signalized and unsignalized intersections. "Level
of Service drops" are those future conditions that result in a negative
change in intersection or approach lane Level of Service, i.e. LOS
D changes to LOS E in future conditions.
MAJOR INTERSECTION
The intersection of any arterial or collector street with
any other arterial or collector street as defined by PennDOT's Functional
Classification Map, the municipal highway classification document
or the equivalent document of adjacent municipalities, where appropriate.
OFF-SITE TRANSPORTATION IMPROVEMENTS
Transportation-related improvements which are generally not
contiguous with the property being developed and not required as an
on-site improvement but are found by the TIS analysis to be necessary,
partly or wholly, as a result of the proposed development.
ON-SITE TRANSPORTATION IMPROVEMENTS
All improvements on or adjacent to the development site in
the public right-of-way required to be constructed by the owner/developer
pursuant to any ordinance, resolution or requirement of the Borough
and the PennDOT or County Highway Occupancy Permit (if applicable).
PUBLIC TRANSIT
The Southeastern Pennsylvania Transportation Authority (SEPTA)
is the provider of most public transit services throughout Montgomery
County. Other local public transit providers operate in some communities.
ROUNDABOUT
An circular intersection design, per NCHRP Report 672, Roundabouts,
An Informational Guide, Second Edition, or as amended, that may be
considered as an alternative to new or expanded signalized intersections.
SCOPING MEETING
A meeting with PennDOT may be required to determine the parameters
of the transportation impact study required for a PennDOT Highway
Occupancy Permit (HOP). A municipal scoping meeting will also be required
prior to the commencement of the TIS to coordinate agreement on municipal
conditions and expectations. County officials will also need to be
involved whenever a county-owned roadway will be included in the TIS.
STUDY AREA
The study area shall be defined at the Municipal/PennDOT
scoping meeting but, at a minimum, shall include all development site
access locations, any intersections immediately adjacent to the development
property as well as all major intersections within 1/2 mile of all
development access locations. Additional intersections may be added
per the scoping meeting. The study area should also identify all transit
routes and transit stops within 1/2 mile of the proposed development
and the location of sidewalks and pedestrian crossings.
1.
Proposals that will generate more than 1,000 new average daily
trips shall expand the study area to include major intersections within
one-mile of the development access locations.
2.
All intersections identified in the study area should be examined,
even if the intersections are located outside of the Borough. (Municipalities
cannot request improvements for study intersections beyond the municipal
border; only PennDOT has this authority.)
TRANSPORTATION IMPACT STUDY or TRAFFIC IMPACT STUDY (TIS)
A study of the transportation network and conditions surrounding
a proposed change or expansion of land uses, conducted to identify
the transportation impacts of the proposed land use change or expansion
and any possible mitigations needed to offset those impacts.
TRIP
A one way trip into or out of the site, and not what is commonly
referred to as a "roundtrip."
TRIP GENERATION RATES
The total number of trips to and from a study site per unit
of land use, as measured by parameters like dwelling units, floor
area or acres. The most current edition of the Institute of Transportation
Engineers (ITE) "Trip Generation Manual" shall be referenced to determine
the specific rates.
WARRANTS FOR TRAFFIC SIGNAL INSTALLATION
A series of tests which identify the minimum vehicular traffic
or pedestrian volumes or other criteria necessary for installation
of a traffic signal. The warrant criterions are available in the current
and PennDOT approved Manual of Uniform Traffic Control Devices, Or
PennDOT's Traffic Engineering Manual (Publication 46).
