Compare like with like
Put loops and one-way journeys in separate comparisons. For a one-way ride, add the return or onward journey you will actually make. For a loop, check that the final leg returns to the selected start.
Open the roadbook before comparing headline distances. Two variants can share a famous pass while following different approach roads, return legs or stop orders.
Read what the route evidence establishes
A checkpoint itinerary identifies intended visits. Road-following geometry identifies a calculated path. Neither is a current inspection of the surface or proof that the road is open.
Keep any source label beside its explanation. A catalogue label carried from an earlier dataset is not fresh independent verification. The source and coverage page explains these boundaries.
Match the date and vehicle
Identify the roads whose operation matters to the journey. Check the relevant published restriction, road-local visit time and vehicle scope. A rule on a nearby road is not automatically a rule on your route.
Use seasonal context to choose a period, then current authority information and forecasts to refine the plan. Do not convert missing evidence into a favourable rating.
Turn a choice into a repeatable plan
Use the ride-day budget to include stops and delays. Save the intended roads in the calendar workspace, retaining their order and any known visit timings.
Before export or navigation, inspect the actual path and required stops again. This guide helps select a plan; it does not certify the current navigation engine or traffic conditions.
