Annual average daily traffic on the national road network
收藏资源简介:
The average annual daily traffic (TMJA) of a road section is obtained by calculating the yearly average of the number of vehicles circulating on that section, in all directions, during a day. These delayed-time traffic data are usually accompanied by an estimate (as a percentage) of the number of heavy goods vehicles used in their composition. Each section of the road is defined by: — his name (road) — its length — its starting (D) and end (F) coordinates expressed in coordinates (X, Y, Z) or by a road tracking system consisting of 4 attributes: — PR = Road marker — depPr = department where the PR is located — concessionPr = indicates whether the PR is on a licensed section (C) or not (N) — ABS = abscissa or distance (in metres) separating the point of the PR to which it relates Other attributes complement these location attributes: — yearMeasureTrafficking = year in which the measurements were made — Type Counting Traffic = indicates whether the counting of vehicles has been carried out from a system permanently placed on the road or whether it is a record using a temporary metering system — TMJA = annual average daily traffic — RatioPL = percentage of heavy weights used in the composition of the TMJA
