Road traffic in Haute-Savoie

Representation of the road network of Haute-Savoie and traffic data. Based on the “N_ROUTE_BDC_074” table of the CARTO BD, traffic data provided by road network operators and the metering maps produced annually by DDT and CD74. Three steps were needed: • selection and merger of road sections of the structuring road network, as well as sections of the non-structuring network with a permanent or temporary metering station; • section numbering and indicating the type of counting (to avoid annual renumbering of counts on departmental roads); • input of traffic data available for each of these sections in 1998 and each year from 2007.
