A quick nod to our private and third sector partners, who you can approach to commission pedestrian and cycle models with sDNA. That’s if you don’t want to download our software and do the job yourself of course! In alphabetical order:
I’m excited to present sDNA version 3 for public beta testing. sDNA 3 is based on feeback from our research partners Arup, WSP, Sustrans and Tongji University, and adds an enormous amount of new functionality both for free and paying users.
- Use Open Source GIS with QGIS Support
- Increased compatibility with network formats (ability to run link-weighted analysis without fixing split links; grade separation and elevation can now be used together)
- Link to other models: export skim matrices from sDNA or use sDNA to assign an external Origin-Destination matrix (sDNA+)
- Easier to install anywhere with offline unlocking and no administrator account required
Enhanced ease of use
- Links can be switched on and off for scenario analysis (sDNA+)
- Do your stats within sDNA, no need for external tools
- Preserve text and numeric data in sDNA Prepare (sDNA+)
- Improved interface to all functions in sDNA, more helpful error messages and it’s less of a CPU hog
- Full user manual – not just for sDNA but guiding you through the theory of spatial network analysis and how to prepare networks
- Produce maps of who uses a selected link (sDNA+)
- Easy to use cycle, vehicle, pedestrian and public transport metrics (sDNA+)
- More realistic behavioural models with hybrid and banded radius, enhanced hybrid metrics for turns (sDNA+)
- Robust multivariate learn and predict tools based on generalized cross-validation
- Geometry outputs are now fully 3d (sDNA+)
- OD Matrix Input and Skim Matrix Output (sDNA+)
Users wishing to test sDNA3 can find it in the downloads folder under experimental. Your previous serial number will work but must be deregistered from sDNA version 2 before uninstalling the old version.
The user manual is here.
Alternatively if you wish to wait, the official release of sDNA3 is scheduled for September 2016.
