Road counts at the station on Rennes Métropole

This layer of data, available only on the geographic data portal, makes it possible to consult statistics from road counting stations on Rennes Métropole. /!\ These data have a “time” component that makes it difficult to operate outside the Rennes Métropole Geographical Data Portal. This statistical data is created from raw data (trafficking and speeds) collected in a business database managed by the Directorate of Highways, Traffic Management and Security department. These raw data come from various sources: \- automatic stations positioned on major axes (SIREDO network) \- annual campaigns programmed on representative points \- one-off campaigns programmed as part of traffic studies \- ad hoc measures on the service network (often at the request of the inhabitants) The various indicators calculated and available on this data are as follows: \- code_rm: code the counting station \- year: most recent year in which measures are recorded \- meaning: direction of recording of measurements (in both directions, one-way) \- tmja_tv: Average Annual Daily Rate (all vehicles) \- tmja_pl: Average annual daily rate (heavy weights) \- v85_tv: speed at which 85 % of vehicles (all vehicles) drive in km/h \- v85_pl: speed at which 85 % of vehicles (heavy vehicles) in km/h drive \- v_medium_tv: average speed recorded (all vehicles) in km/h \- v_medium_pl: average speed recorded (heavy vehicles) in km/h \- debit_hpm_tv: average flow Full Morning 8h-9h (all vehicles) \- debit_hpm_pl: medium flow Full Morning 8h-9h (heavy weights) \- debit_hps_tv: average flow Full Hours Even 17h-18h (all vehicles) \- debit_hps_pl: medium flow Full Hours Even 17h-18h (heavy weights) A guide to the use of this data layer on the Rennes Métropole Geographic Data Portal is attached to this metadata sheet.
