02Route 3D - Multi-Criteria 3D Mobility Studio QGIS 4 compatibility

02Route 3D finds and inspects routes the way different people actually move through a city. It routes over your own QGIS line network or a bounded OpenStreetMap download, scores every edge with a multi-criteria (AHP) cost built from terrain, optional environmental rasters, road hierarchy, surface, one-way rules and access tags, and shows the result in an interactive 3D (WebGL) route viewer. MOBILITY PROFILES (15) Standard Adult, Senior, Child / Safe Walk, Stroller, Wheelchair / Barrier-Free, Runner, City Bicycle, Mountain / Gravel Bike, E-Scooter, Passenger Car, Delivery Van, Heavy Goods Truck, Emergency Responder, Scenic Walk and Safe Night Walk. Each profile has its own speed, slope, stair, surface and road-class limits, and every tool applies the same limits: a wheelchair route never crosses stairs, whichever tool computed it. ANALYSIS TOOLS (16) - the Tools tab of the dock All sixteen tools run from the dock's Tools tab (point picker, layer and field choices, background run with progress and cancel, result layers added to the project). Points, DEM, road network, buildings and the last route are filled in from the dock. Nothing is added to the Processing Toolbox. - Routing: Compute 3D Route (turn costs, time of day); Transit + Walk Route (GTFS, RAPTOR); Multi-Objective Pareto Routes (NAMOA*); Batch Route Planner; Origin-Destination Cost Matrix; Emergency Evacuation & Hazard Avoidance. - Accessibility: 3D Isochrone (street-corridor service area); Accessibility & Equity Scorecard (E2SFCA, Gini); Walkability & Barrier-Free Audit; Solar & Shade Exposure (building shadows). - Network and data: Routing Network Readiness Audit; MCDA Friction Surface; GPS Track Map Matching (HMM / Viterbi). - Reports and export: Route Scorecard (HTML); Standalone 3D WebGL Report; AutoCAD DXF (3D polyline + profile). CHECKED BEFORE AND AFTER ROUTING The readiness audit marks blocked segments, one-way links, disconnected parts and surface problems before you route. Every route reports how far its ends were snapped to the network, how many nodes were explored and which edges it had to avoid. Walking times follow Tobler's hiking function; energy use follows Minetti's metabolic cost model. OUTPUTS LineStringZ layers, GPX 1.1, 3D GeoJSON, AutoCAD DXF and self-contained offline 3D HTML.
