Statistical Process Control
A collection of problem solving tools useful in achieving process stability and improving capability through the reduction in variability.
Urban Area (census)
-An urbanized area (UA) is an urban area with population over 50,000. The Census Bureau’s urban areas represent densely developed territory, and encompass residential, commercial, and other non-residential urban land uses.
Census Tract
small, relatively permanent statistical subdivisions of a county or equivalent entity that are updated by local participants prior to each decennial census as part of the Census Bureau’s Participant Statistical Areas Program. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people.
Census Block
-Smallest Census Unit- are statistical areas bounded by visible features, such as streets, roads, streams, and railroad tracks, and by nonvisible boundaries, such as selected property lines and city, township, school district, and county limits and short line-of-sight extensions of streets and roads.
Regression Analysis
-statistical technique which provides an estimate of one
variable based on a linear function of another. The coefficient of determination or varies between 0 and I and indicates the percentage of the variance in the dependent variable explained by the independent variable.
Confidence Interval
-a range of values that includes a certain population parameter (e.g., the mean) with a given probability.
Test of Hypothesis
-probability test that relates a sample based estimate to a population related hypothesis, and allows for either acceptance or rejection of this hypothesis.
principal arterial road
-Principal arterials serve longer trips, carry the highest traffic volumes, and carry a large percentage of the VMT on minimum mileage and provide minimal land access.
minor arterial road
-Minor Arterials interconnect the principal arterials, provide less mobility and slightly more land access, and distribute travel to smaller geographic areas than principal arterials.
collector road
-Urban Collectors provide both land access and traffic circulation with residential, commercial, and industrial areas by collecting and distributing traffic to these areas.
local road
Local Streets provide direct access to adjacent land and access to the higher classified streets.
