| abstract |
Traffic flow modelling from Zenith model covering Sydney, Melbourne, Brisbane, Adelaide, Perth, ACT, and North Queensland regions in 2018. The model simulates the interaction of every traffic zone to every other traffic zone in a model area, with consideration of where, when, why and how everyone travelled. Most recent publicly available traffic counts from state and local governments are then used to produce Zenith traffic estimates. Estimates may contain aberrations, for instance, due to seasonal variations, weather conditions or public/school holidays. A matrix estimation process is used to fine tune the simulated traffic volumes to that of the traffic counts. The geodetic datum is WGS84. The variables in the data are given as FieldName - Description name - Road Name linkid - Linked anode - Link start node bnode - Link end node direction - Whether the link direction is from node a to b or b to. It also indicates if the road is oneway load_total_24 - 24 hour volume (all vehicles) load_commveh_24 - 24 hour volume commercial vehicles total load_total_am - Total volume (7-9am) load_total_md - Total volume (all remaining hours) load_total_pm - Total volume (4-6pm) vc_am - Volume/ Capacity Ratio AM vc_md - Volume/ Capacity Ratio all remaining hours vc_pm - Volume/ Capacity Ratio PM calcspeed_car_am - Average link speed AM calcspeed_car_md - Average link speed MD calcspeed_car_pm - Average link speed PM |
