TRANSPORTATION PLANNING GLOSSARY
Access
Management
Access Management is carefully controlling the design, location, and
overall operation of all driveways and public street connections to a
roadway.
This function works to improve traffic safety and
movement causing a decrease in traffic accidents.
Arterial
Arterials are generally considered major streets that
move traffic across the city.
More specifically they form a continuous
sub-network designed to feed limited access facilities
and other roads.
Overall, they serve mobility functions around and
through urban and community activity cores.
Collector
Collectors are generally considered neighborhood streets
that collect local street traffic, serving community and
neighborhood activity cores.
More specifically a collector is a facility that
distributes trips between local streets and the arterial
network balancing the need for individual lot access and
traffic mobility.
Collectors serve residential, commercial, and industrial
areas by collecting the traffic generated and providing
continuity between local roads and the rest of the
system.
Connectivity
Connectivity are improvements to the overall city
roadway network, including internal and adjacent site
connections, which allows several routing choices that
are easily comprehensible to pedestrians and
automobiles. Road systems with good connectivity
help disperse traffic patterns, such as a traditional
city street grid.
Corridor
Corridor is a general term used most often to describe a
major artery and its surrounding area, including side
streets and parallel arteries.
Corridor studies are performed on major
thoroughfares to determine the level of need for
improvements in accommodating a multimode transportation
system.
Level of Service
Level of Service is a description of the condition of a
roadway segment, or other mode of transportation such as
transit service, to handle traffic volume.
Generally, roadways or transportation areas are
categorized from Level of Service "A", where there is
little or no travel delay, to Level of Service "F",
where roadway capacity is exceeded and characterized by
long queue lines, back-ups, and stopped vehicles for
long periods of times.
Major Thoroughfare
Major Thoroughfares include all collectors, arterials,
and limited access roads but do not include local roads.
Thoroughfares serve two purposes:
moving traffic between dispersed parts of the City, and
providing public access to individual properties located
on the thoroughfare.
This dual role of major thoroughfares is conflicting as
the traffic movement function of thoroughfares can be
compromised by the provision of access to individual
properties. The Major Thoroughfare Plan was developed to
balance these roles by recognizing both the rights of
property owners to reasonable access and the public
purpose of efficient traffic flow.
Multi-Modal
Multi-Modal is an interchangeable system of all forms of
transportation, from pedestrian to inter-city passenger
rail, which encourages alternatives to automobile
commuting. Includes seamless transfer points where
multiple land-uses may locate, such as residential and
retail mixed-use projects which reduce the need to make
additional trips.
Traffic Calming
Involves
the creation of attractive design features to narrow
travel lanes and regulate intersection traffic resulting
in slower traffic speeds.
This device
is frequently implemented in residential areas
to ensure resident safety and community livability.
Examples include:
speed humps, bricking, landscaped medians, and
roundabouts.
Traffic Counts
Traffic counting is generally recording the number of
cars passing through a specified intersection or driving
a certain road on a given day.
Traffic Counts are used to determine if improvements are
necessary to intersections and roadways to accommodate a
multimode transportation system.
Transportation Concurrency Management
Transportation Concurrency Management is a program
designed to guarantee Orlando’s transportation
facilities are designed to accommodate imminent growth
and development.
Transportation Demand Management
Transportation Demand Management is a solution that
relieves traffic congestion on highways and promotes
transportation alternatives to reduce the reliance on
single-occupant vehicles. Programs of Transportation
Demand Management may affect travel frequency, mode,
destination or timing and are implemented through
varying means; such as, rideshare matching, transit
improvements, bicycle and pedestrian facility
improvements, parking management, promotion of
alternative modes, flexible work schedules, transit
subsidies and telecommuting. These can provide
significant financial savings to governments, businesses
and consumers, as well as environmental benefits.
