Roadstr 0.4.17

Roundabout signs that match the junction in front of you.

Added

  • Real roundabout shapes. A routing engine only tells the app which exit to take —
    "third exit" describes a four-arm junction and a seven-arm one equally well, and until
    now the sign drew the same generic ring for both. The number of arms is now read from
    OpenStreetMap and drawn, so the symbol you glance at looks like the junction you are
    approaching. Where OSM has no usable ring mapped, the sign falls back to the generic
    one rather than inventing a shape.

  • Cursor styles. City, racing, SUV, electric, bicycle and formula, alongside the
    existing arrow.

  • A redrawn speedometer.

Under the hood

The roundabout lookup is deliberately bounded, on two counts.

It batched every roundabout in every alternative route into a single OpenStreetMap query
with no limit. A city route through France or the UK can pass fifty of them, which is a
hundred search clauses sent in one request to a free, volunteer-run server — the same
infrastructure this app went to some trouble to stop hammering two releases ago.

The second reason matters more. Each of those coordinates is a piece of your itinerary,
sent in one request before you have even set off. Every other OpenStreetMap lookup in
Roadstr discloses only where the car is, progressively as you drive — never where it is
going. The lookup now asks about at most 24 roundabouts, nearest first, with a test that
an 80-roundabout route cannot exceed that.
