Update

Reconstruction mode for refreshing an existing route while preserving its geometry.

This mode is intended for updating routes originally produced by custom or third‑party routing services, ensuring that the polyline shape remains intact during the process.

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

During reconstruction, the algorithm strictly adheres to the input polyline and does not allow significant deviations. It makes a best effort to maintain the original geometry while rebuilding the route.

ConsiderTraffic is ignored during the search.

This mode has the highest likelihood of successfully producing a reconstructed route, though the result may be suboptimal or even illegal if traffic closures or routing restrictions affect the intended path.
