Accessibility calculator 7.0 — QGIS Python Plugins Repository

Changelog

7.0
- New "Roundtrip" Approach to Accessibility Computations: A novel
roundtrip methodology for accessibility computations is finalized.
- UI & UX Refresh: Restructured and clarified the main menu and dialog
boxes for a more intuitive user experience.
-       JSON Integration: By leveraging GTFS datasets and the layers
of road network and buildings layers, the transit and car routing
databases are constructed to enable rapid data retrieval during
accessibility computations. This integration replaces the pkl format
used in previous versions, which was recently flagged as a security
risk by QGIS.
- GeoPackage Integration: Computational outputs are now natively
stored in the GeoPackage format for better data interoperability.
- Dynamic GTFS Editing: Added the ability to directly modify GTFS data
by adding or deleting transit lines.
- Documentation: Updated the official tutorial to reflect all recent
features and accumulated changes.
- Bug Fixes: Resolved minor bugs and improved general stability.
6.3 (experimental)
- Feature Update: Introduced Roundtrip accessibility analysis.
6.2
- Maintenance: Fixed minor bugs.
6.1
- Maintenance: Fixed minor bugs.
6.0
- UI Enhancements: Improved and clarified user interface layouts and
dialog boxes.
- Streamlined Workflow: Restructured the processing pipeline by
removing the standalone "Database Construction" menu section.
- Transit routing database construction is now integrated directly
into the transit accessibility calculations block.
- Car routing database construction is now integrated directly into
the car accessibility calculations block.
- Contextual Help: Added dedicated explanation panels to the right
side of option dialogs to guide users.
- Global Testing: Tested and validated the software across multiple
global GTFS datasets representing diverse international cities.
- Performance: Significantly optimized the execution speed of core
computational procedures.
- Data Validation: Added a pre-construction validation check to test
the availability and completeness of road layer attributes.
