Traffic is counted or estimated by various methods. Adjustments are made to annualize the counts because individual counts vary with time. AADT and the associated attributes are developed by the traffic and field ops unit (TFO) and statewide planning. Both the state and NUSYS AADT is loaded every year. State system AADT is loaded into CANSYS annually after state system network maintenance is complete. TFO engineer completes the load process TFO engineer modifies TRAF (traffic segments asset item) to make the AADT load process work. NUSYS AADT is loaded into CANSYS annually after NUSYS network maintenance is complete. NUSYS AADT loads actual counts received from TFO on a 3-year cycle. (2 districts per yr.). The other four districts estimate AADT from the previous year counts existing in CANSYS by using a short-term (yearly) growth factor given by TFO. AADT records are not end dated each year. Since 2004, AADT records are kept open, this allows for the AADT assets to be relocated when network maintenance is applied. After the AADT load is complete for the year, the exclusive views need to be recreated. AADT is located based on the TRAF segment (TRAF) location data is contiguous over the network because the loaders use previous years records for values (expansion factor- directional split- k factor). Dummy recs are made by TFO for the previous AADT year in areas where net MAINT caused an AADT gap. records are created with a 0 or 1 AADT count.History:Until year 2004 AADT assets were end dated and history was kept in the A0XX foreign tables. Keeping the AADT records open allows for the AADT assets to be relocated when network maintenance is applied. The A0XX foreign tables exist, but the data is not complete.(AADT) - % Heavy Commercial -- IIT_NUM_ATTRIB22 Percent of AADT of all vehicles having more than two axles or four tires (heavy commercial) (AADT) - AADT Count -- IIT_NUM_ATTRIB16 Count of all traffic. On undivided roadway this is the total count. On divided roadway this is 1/2 of the total count. Rounded to the nearest 5 vehicles.(AADT) - AADT Count Year -- IIT_NUM_ATTRIB76 The year the AADT_Count represents History:Some of the early materialized views do not include the count year (AADT) - Count Date -- IIT_DATE_ATTRIB86 The date represented by the count. Usually 01 Jan of the count year. In NUSYS this is also the date the actual count was taken. In NUSYS, for two subsequent years the AADT count will be updated by expansion factor but the count_date is not updated.(AADT) - DIRECTIONAL SPLIT -- IIT_CHR_ATTRIB29 The percent of total traffic in the heavier direction during the peak period. (AADT) - EXPANSION FACTOR -- IIT_NUM_ATTRIB17 The anticipated annual rate of expansion (deflation) of the count for each year in the future for the next 20 years. (AADT) - Expnsn Factor Date -- IIT_DATE_ATTRIB87 The date the expansion factor is effective.(AADT) - FUTURE AADT -- IIT_NUM_ATTRIB18 Equals current AADT count times expansion factor to 20th power. Calculated by a trigger anytime the count is created or modified.(AADT) - HEAVY COMMERCIAL -- IIT_NUM_ATTRIB21 Average annual daily count of all vehicles having more than two axles or four tires--- counts of vehicles in traffic monitoring guide (TMG) classes 4 to 13 are aggregated as hvy commercial.

This data has an implied decimal thus a value of 11 is actually 0.11(AADT) - MEDIUM TRUCK -- IIT_NUM_ATTRIB24Average annual daily count of all vehicles that are built on a single frame and having more than two axles or four tires. Counts of vehicles in traffic monitoring guide (tmg) classes 4 to 7 are aggregated as single unit counts (medium truck).
