get_transaction_roads
Get the plot-by-plot road-access evidence for one transaction: for each linked plot, the distance in meters to the nearest public road, to the nearest road of any kind, and to the nearest motorway/expressway/dual-carriageway — plus, for the nearest public road, the estimated distance to the EDGE of its carriageway, its management category ('national' | 'voivodeship' | 'county' | 'municipal'), its functional class ('motorway' | 'expressway' | 'main_accelerated' | 'main' | 'collector' | 'local' | 'access' | 'other') and whether it runs at ground level (false = it crosses on a viaduct or in a tunnel, so it passes the plot over or under it). Each plot also carries access_indicator ('likely' | 'uncertain' | 'unlikely') and the version of the rule that produced it. access_indicator is GEOMETRIC EVIDENCE measured from carriageway centrelines in reference road-network data. It does NOT determine legal access and says nothing about easements or rights of way, which are recorded in the land register and are not published here — treat it as a lead to verify, never as a conclusion. That is why it has three states and is never a yes/no. Each measurement has a fixed radius: public road 500 m, road of any kind 500 m, motorway/expressway/dual-carriageway 3 km (that last one is a traffic-nuisance proxy, not an access signal). public_road_edge_distance_m is null when the source carries no carriageway width — no median is substituted. Use it for a specific transaction to judge how its land sits relative to the road network. get_parcel_report includes a one-line road-access summary per parcel. TWO-STATE: a null/absent distance means no such road within the search radius in the reference data — it is NEVER a guarantee that none exists. assessed=false means the plot has not been evaluated yet (no statement either way). Cost: 4 tokens (refunded when there is no informative data — no linked plots, or none evaluated yet).
