US Road Traffic Volume
The national pulse of US road travel: monthly total vehicle-miles travelled on all US public roads since 2000, from FHWA's Traffic Volume Trends. The raw artifact is a 13-sheet Excel report republished monthly; this is the one clean continuous national VMT series.

European EV Charging Buildout (EAFO)
The installed base of electric-vehicle recharging points across Europe, per country over time - the European mirror of the US EV-charging buildout. From the European Alternative Fuels Observatory (EAFO/DG MOVE): the AFIR-methodology quarterly AC/DC split (2020→present) plus the pre-AFIR annual totals (2012-2019), stitched into one clean multi-country Parquet keyed by country code. Note: AFIR counts recharging POINTS (connectors), not stations/sites.
European Transport
The land-transport pulse of Europe in one panel: rail freight (thousand tonnes) and rail passengers (million passenger-km), plus the passenger-car fleet and new-car registrations split by fuel (total / petrol / diesel). Cleaned from Eurostat transport statistics into one tidy annual per-country table - the mobility and fleet-transition signal that complements our road-freight and air-passenger products.
European Road Freight
The road-logistics pulse of Europe in one clean Parquet: annual road freight moved (million tonne-kilometres) by each country's hauliers, split into national and international transport, one row per country × series × year since 2000. A read on trade flows, supply-chain activity and the freight economy; joins to macro, trade and energy on country code.
