| Abstract | These data are combined from Zenith 2018 traffic counts and StreetPro 2012 road network. The geometry is based on the StreetPro road network subset to 10km buffers around AP monitor stations and simplified to smooth the roads. |

| Abstract |
These data are combined from Zenith 2018 traffic counts and PSMA 2019 road network. The geometry is based on the PSMA road network. Zenith traffic data, total and commercial loads as vehicles per day (vpd), was first assigned to closest matching PSMA line segments. Unmatched road segments were then imputed with values from neighbouring lines (up to 11 line segments away from a directly matched line segment). All remaining roads without a value were then imputed using the 20th percentile vehicle per day count of all roads of the same subtype (subtype_cd) and road class (thier_code). The variables ldttl, ldttl_nb, ldttl_avg, ldcomm, ldcomm_nb and ldcomm_avg are intermediary results of the traffic load line segment matching and imputation described above. The combined matched and interpolated vehicle per day counts are given in variables vpd (total traffic load) and vpd_comm (commercial traffic load). Note some dual carriageways are represented by two separate (parallel) lines, but the full bidirectional traffic load is assigned to both lines. Originally produced for use in the APMMA project. |

| Abstract |
These data are combined from Zenith 2018 traffic counts and StreetPro 2012 road network. The geometry is based on the StreetPro road network. One of the main attributes is the gis_class variable. This was created as WHEN roadtype_broad IN (‘highway’, ‘motorway’, ‘main’, ‘connector’) THEN ‘major’ WHEN roadtype_broad IN (‘local’, ‘minor’) THEN ‘minor’ |
