Route

Reconstruction mode for importing routes generated by custom or third‑party routing services.

This mode should be used when the provided polyline represents a route that is already expected to align closely with the road network.

The input polyline is assumed to reasonably follow road geometry, contain no large gaps between points, and avoid loops within the same route leg.

During reconstruction, the algorithm strictly adheres to the polyline and does not tolerate significant deviations from it. It attempts to produce a legal and locally optimized route, allowing only minimal divergence when necessary.

This mode has a higher likelihood of resulting in a NoRouteFoundFailure if traffic closures or routing restrictions block the intended path.
