0.7.4
- Fix: plugin dialogs no longer use the blocking exec() call; the
GISBR notice now opens window-modal without blocking QGIS.
- Passes the plugins.qgis.org security scan (0.7.2 and 0.7.3 were not
published).
0.7.3
- Fix: errors are no longer silently swallowed when reading link
attributes; a missing link id field now raises a clear error instead
of falling back to feature ids.
0.7.2
- Fix: QGIS no longer asks to install GISBR when it is already
installed (plugin_dependencies removed from metadata).
- When GISBR is missing, a single window suggests installing it, with
a shortcut to the Plugin Manager and a "Don't show again" option.
0.7.1
- Fix: centroid connectors no longer appear in the assignment output
layer (AoN, MSA, FW).
- Fix: link_id is written as an integer field when the source id is
numeric (text only for non-numeric id fields).
0.7.0
- Frank-Wolfe equilibrium traffic assignment method with exact line
search.
- Highway layer parameters: capacity, free-flow time, and one-way
direction read directly from layer attributes (overriding HCM
calculation).
- Mapped fields in the traffic panel are properly resolved (previously
fell back silently to default).
- Link-level BPR alpha and beta parameters applied per arc.
- Updated convergence defaults to 100 iterations and 0.001 relative
gap.
- End-to-end benchmark regression validation against Sioux Falls user
equilibrium reference dataset.
0.6.2
- Fix: highway assignment drew connections that do not exist in the
network where network nodes are close together. Each centroid is now
anchored to the nearest point of the nearest link (the link is split
there) instead of the nearest node, and the connector carries the
zone's trips.
- Warnings for long connectors, centroids sharing a node or link,
ambiguous anchoring and the zones left unconnected.
- Output layer: new "tipo" field (link, link_dividido, conector);
connectors are drawn as grey dashed lines.
- The run stops with a clear message when a layer's coordinates do not
match its CRS label.
0.6.1
- Fix: highway assignment no longer creates links that do not exist in
the network when the layer is in a geographic CRS (e.g. GisBR
EPSG:4674, EPSG:4326) — the network is now reprojected to a metric CRS
before snapping, lengths and connectors.
- Fix: zone connectors can no longer be chained into a shortcut
between two network nodes.
- Regression test on the Sioux Falls benchmark network.
0.6.0
- Single toolbar button with drop-down menu.
- GisBR download by metropolitan area, micro-region, meso-region and
health macro-region.
- State road network picked from the GisBR catalogue (adds Goiás).
- Fix: assignment output layer now opens (layer name was `None` and a
layer source in the output field duplicated the path).
0.5.0
- Highway traffic assignment moved to a dockable panel.
- HCM parameters organized into a dedicated tab.
- Scrollable pages added for improved interface flexibility.
- Removed highway traffic assignment tab (Tab 4) from the main dialog.
0.4.0
- New "Alocacao em rodovias" tab: traffic assignment over the real
highway network (official DNIT/SNV and DER mesh via the GisBR plugin)
with per-direction capacity computed by HCM 6th ed. procedures (ch. 15
two-lane, ch. 12 multilane/freeway).
- Two assignment methods, same inputs and same outputs: All-or-Nothing
(single pass, no capacity restraint) and Equilibrium MSA + BPR
(iterative, with relative gap).
- Separate "Compute capacity" action: returns the mesh with capacidade
and the src_* provenance of every parameter, before any assignment.
- Output layer carries volume, capacidade, v/c, approximate LOS (by
v/c band), time, delay, method, scope and per-parameter provenance,
styled by v/c.
- Missing HCM parameters are never assumed silently: each has a
documented default, is overridable globally or by layer field, and its
effective source is recorded.
- Urban crossings inside the highway mesh are flagged escopo='urbano'
and counted with a warning: urban capacity follows a different
procedure and is out of scope.
0.3.2
- Fix Qt6 enum-scoping compatibility issues for QGIS Plugin
Repository.
0.2.0
- New "AoN (Delaunay)" tab: All-or-Nothing allocation over a Delaunay
network of zone centroids, following least-cost paths. Optional "Split
by direction" output (flow_ab / flow_ba).
- Automatic metric CRS selection for routing (UTM zone, or SIRGAS 2000
/ Brazil Albers EPSG:10857 for wide areas).
- Inputs can be assigned from existing project layers; no longer tied
to imported-layer names.
- Configurable output GeoPackage with sensible fallback, plus live
input validation.
- Desire lines and AoN flows styled with a graduated (Natural Breaks)
renderer, fully editable from the Symbology panel.
0.1.0
- Initial release: build OD desire lines from a CSV matrix and
traffic-zone centroids.
