2040 Growth Concept – A long-range regional growth management and urban form concept adopted by
Metro in 1995. The concept classifies land into ten urban form categories, including intensely developed cen-
ters and corridors, open spaces and rural reserves intended for preservation, and neighborhood areas that
will remain mostly unchanged. Local comprehensive plans must demonstrate compatibility with the concept.

Access – The ability to have direct ingress and egress to or from a specific property or other location along
a roadway. Local Streets providing direct access to individual properties generally have better access than
Arterial roads or Freeways, whose primary purpose is to serve through travel. Access can also apply to non-
roadway facilities such as trails.

Accessibility – The relative ease with which a given destination or land use can be reached by one or more
modes of travel. Locations that can be accessed by many people using a variety of modes of transportation
generally have high accessibility.

Access management – Measures that regulate or restrict access to roadways from private driveways, parking
lots or other roadways. Measures may include but are not limited to restrictions on the siting and quantity of
driveways, restrictions on the spacing and traffic control of intersections, and use of physical devices such as
medians and traffic signals to reduce the impacts of traffic intersecting or approaching the main facility.

Accessway – A paved pathway that provides pedestrian and bicycle access when a full street connection is
not practicable. ADOPTED TEXT

Active transportation – Human powered travel, including walking, bicycling, skateboarding and the use of
mobility devices such as wheelchairs (including motorized wheelchairs). Active transportation is sometimes
considered to include public transit because accessing transit stops typically involves walking or bicycling.

Adaptive signal control – An intelligent transportation system technology that uses real-time traffic informa-
tion collected from camera or other sensors to coordinate and optimize signal timing at multiple signalized
intersections in a corridor. The primary goal of adaptive signal control is to reduce congestion, delay and
travel times.

Advanced Traffic Management System (ATMS) – Traffic management techniques that use computer process-
ing and communications technologies to optimize performance of motor vehicle, freight and public transpor-
tation systems.

American Community Survey – An ongoing statistical survey administered by the US Census Bureau that
samples a small percentage of the population every year to provide demographic, socio-economic and other
community information. Transportation-related data includes travel modes and travel times for the commute
to work.
