Road counts at the station on Rennes Métropole

This layer of data, available only on the geographic data portal, allows you 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 Geographic Data Portal.

These statistical data are created from raw data (traffic and speeds) collected in a business database managed by the Roads Directorate, Traffic and Safety Management Department. These raw data come from various sources:
- automatic stations positioned on major axes (SIREDO network)
- annual campaigns programmed on representative points
- ad hoc campaigns programmed as part of traffic studies
- ad hoc measures on the service network (often at the request of the inhabitants)

The different indicators calculated and available on this data are as follows:
- code_rm: code the counting station
-year: most recent year in which measurements are recorded
- meaning: sense of recording of measurements (in both directions, one-way)
- nb_weeks: number of weeks of capture (if 0.1 = 1 day)

- tmja_pl: Average Annual Daily Rate (heavy)
- v85_tv: speed at which 85 % of vehicles (all vehicles) drive in km/h
- v85_pl: speed at which 85 % of vehicles (heavy vehicles) drive in km/h
- v_medium_tv: average recorded speed (all vehicles) in km/h
- v_medium_pl: average recorded speed (heavy) in km/h
- debit_hpm_tv: average flow time Full Morning 8h-9h excluding WE (all vehicles)
