AADT (Annual average daily traffic) = the total volume of
traffic on highway segment for one year divided by the
total number of days in a year.
KFCTR (Design hour traffic) = proportion of aadt occurring in an
hour.
DFCTR (Directional distribution factor) = the percent of the
total two-way hourly traffic that occurs in the peak
direction.
TFCTR (Truck factor) = the percent of truck traffic for a 24 hour
period.
SITETYPE TELEMETERED (stationary) or PORTABLE.
COMM Location of the traffic meter
CLASSD Relates to truck factor data
DESCRIPT Derived from AADT.
USER NOTES:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the multi-county or regional level.
1:250000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at:
