ALT_ID: Alternate Traffic Count Station ID Number
TOWN: Town Name Abbreviation
FIPS: (US Census) http://www.census.gov/geo/www/fips/fips.html
CNTYEAR: Year of latest known Count.
MM: Milemaker/Milepoint or Position of Traffic Count.
LOCATION: Site location text description
JURIS: Jurisdiction (Agency) undertaking traffic count – “V” = VTrans.
ALT_RT: Alternate Route Identifier – “THxx” = Town Highway, “VTxx” = State Route, “USxx” = US Route.
POLE: Utility Pole Identifier Number
C1958 … C2014: Annual Average Daily Traffic (AADT), by year. It is a average amount of vehicular traffic in both directions of travel, passing on a given point of road, over a 24-hour period, on a typical day of the year.
NOTES: Special information about the traffic count station location.
T1994 … T2014: Annual Average Daily Truck Traffic (AADTT), by year. This truck traffic includes all trucks for FHWA vehicle classes ‘2 AXLE 6 TIRE’ through ‘GREATER THAN 6 AXLE MULTI’ and the ‘NOT CLASSED’ Vehicles for ACRPC data. VTrans Truck data was obtained from a modified “Automatic Vehicle Classification History” spreadsheet, obtained from the Traffic Research Unit at VTrans.
ZT2002 … ZT2014: 5 Axle Truck AADT, by year.
FUNC_CL: U.S. DOT/FHWA Functional Classification Codes (*see Attribute notes side).
RD_CLASS: Class of Town Highway where the Traffic Count Station exists (*see Attribute notes side).
RAW1994 … RAW2014: Flag indicating if Raw count files are available at http://126.96.36.199/transportation/data/.
AB_DIR: Indicates the A and B Direction of Travel (i.e. originating from the ATR “A Tube” to the “B Tube”). This should indicate in cardinal directions for vehicle travel (e.g. NB/SB, or WB/EB, etc.). The first direction is always the A-direction (e.g. NB – Northbound, EB – Eastbound, etc.). This is hopefully assuming that the A-Tube is always installed in the right-most port upon the ATR. This gives the planner the potential ability to help determine direction of travel of traffic on the count, post-count.
Z5TH_A2000 … Z5TH_A2014: 85th Percentile Speed captured for the A-Direction.
Z5TH_B2000 … Z5TH_B2014: 85th Percentile Speed captured for the B-Direction.
PACE_A2000 … PACE_A2014: 10mph Pace Speed captured for the A-Direction.
PACE_B2000 … PACE_B2014: 10mph Pace Speed captured for the B-Direction.
ASPD_A2000 … ASPD_A2014: Average/Mean Speed captured for the A-Direction.
ASPD_B2000 … ASPD_B2014: Average/Mean Speed captured for the B-Direction.
