Corridors, weather and the heads-up
A corridor is drawn from your own trips: runs of thirty kilometres or more that repeat within a few kilometres of each other, routed over OpenStreetMap on our own box. Along each corridor the box reads the weather every hour from Open-Meteo: storm, heavy rain, fog, wind, rain, with the kilometre and the hour. Traffic along the corridor comes from Google when that key is set, corridor by corridor, never per vehicle.
The desk's Nazar room shows the overlay and the corridor ledger; a vehicle's page shows the line ahead: where it is going, the kilometres left, the arrival time and the delay against the usual. In the cab, Pinger shows one line, the heads-up, in the driver's language: fog on the ghat at km 51 in the morning.
All of it is marked MODELLED, and the sources are named beside it. The weather is a warning to a person who knows the road, not an instruction.
