A QGIS processing plugin for transit accessibility analysis on the Conveyal R5 routing engine — travel-time matrices, cumulative-opportunity accessibility and isochrones over a departure-time window, computed inside QGIS with no R, no conda and no Docker.

Status: 0.3.1, experimental. All fifteen algorithms work; the travel-time matrix and accessibility are verified end-to-end (accessibility reproduces r5r’s Gdańsk output exactly — docs/notes/validation-gdansk.md). New in 0.3.0, each verified on a real Łódź network: network scenarios (draw a new line, remove or re-time routes — R5 applies them in memory) with Compare scenarios, a GTFS pre-flight check, 2SFCA competitive accessibility and a population-weighted equity summary — see docs/prd/PR_easy-R5_v03.md. The flag stays experimental until a clean-install run of the full pipeline is signed off. See KNOWN_ISSUES.md.
