{"name": "Traffica UE Analytics", "package_name": "traffica_ue_analytics", "description": "Traffica UE Analytics is a QGIS plugin designed to perform indicative traffic flow analysis using spatial network modeling and synthetic origin-destination generation.\n\nThe plugin converts road network geometry, population distribution, and point-of-interest (POI) data into a synthetic mobility demand model\nand assigns the resulting flows onto the road network using transport assignment algorithms.\n\nThe analytical framework integrates gravity-based trip generation, grid-based zoning, and network-based route assignment\nto estimate traffic flow patterns where traditional OD survey data is unavailable.\n\nThe plugin supports both deterministic All-or-Nothing (AoN) assignment and probabilistic multi-path assignment using a Path-Size Logit (PSL) formulation,\nenabling the exploration of route choice variability within urban transport systems.\n\nOptional User Equilibrium (UE) iterations using the Bureau of Public Roads (BPR) congestion function and Method of Successive Averages (MSA)\nallow approximate congestion feedback within the synthetic traffic model.\n\nThe plugin includes the following main analytical components:\n1. Network Preparation \u2013 splits road networks at intersections and filters non-vehicular links to build a clean transport graph.\n2. Grid-Based Zoning Generator \u2013 creates spatial zones within a study boundary to serve as origin and destination units.\n3. Synthetic OD Generator \u2013 estimates trip flows using a gravity model based on population mass and POI attraction.\n4. Traffic Assignment Engine \u2013 assigns OD flows to the network using AoN or probabilistic multi-path route choice models.\n5. Congestion Simulation \u2013 applies BPR travel time functions with optional User Equilibrium iterations.\n6. Mobility Output Generator \u2013 produces edge flow layers, OD desire lines, and zone-level mobility indicators.", "about": "Traffica UE Analytics provides an integrated spatial analytics framework for exploring urban mobility patterns\nusing open spatial datasets and network modeling techniques.\n\nThe plugin is designed to support transport planners, urban researchers, and spatial analysts\nin conducting preliminary traffic flow assessments when detailed mobility survey data is unavailable.\n\nBy combining spatial zoning, gravity-based demand modeling, and network assignment algorithms,\nthe framework enables rapid evaluation of potential traffic corridors, congestion hotspots,\nand accessibility relationships within urban regions.\n\nThe resulting outputs can support corridor screening, scenario comparison,\ninfrastructure planning analysis, and urban mobility research within a GIS environment.", "homepage": "https://github.com/firmanaf/Traffica-UE-Analytics", "repository": "https://github.com/firmanaf/Traffica-UE-Analytics", "tracker": "https://github.com/firmanaf/Traffica-UE-Analytics/issues", "author": "Maya Safira, Firman Afrianto", "tags": ["network analysis", "urban planning", "traffic assignment", "gravity model", "urban mobility", "transport planning", "spatial analytics", "transport analysis", "user equilibrium", "origin destination"], "downloads": 451, "latest_version": "1.0.0", "versions": [{"version": "1.0.0", "experimental": false, "qgis_min": "3.0.0", "qgis_max": "3.99.0", "downloads": 451, "uploaded_by": "firmanafrianto", "upload_datetime": "2026-03-15T11:11:00.008774"}]}
