sDNA is world leading spatial network analysis software, compatible with both GIS and CAD. We use the industry standard network representation to produce metrics that correlate to human health, community cohesion, land values, town centre vitality, pedestrian and cyclist flows, land use, traffic volumes, accidents and crime.
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 … Continue reading
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 … Continue reading
The sDNA team – partnered up with Sustrans – were invited into the Welsh Assembly by AM Jenny Rathbone on Tuesday. Together we are keen to ensure that the Welsh Government follows through on its commitment to Active Travel set … Continue reading
In the soon-to-be-released sDNA3, it will no longer necessary to repair split links. This looks like a departure from how sDNA used to work, so I’d better explain it. First, let’s clarify what we’re talking about. A split link is … Continue reading
Crispin gave an invited talk at Association for Geographic Information’s “GeoBig5: Big Data and You” conference on the links between spatial network analysis and big data. To summarize, Spatial network analysis leverages existing large datasets by extracting novel information from … Continue reading
Crispin will be presenting sDNA models of pedestrian and cyclist travel at the Association of European Schools of Planning Conference, Prague, 14th July 2015. As ever, get in touch if you would like to meet up.
Crispin & Alain will both be at the Transport Practitioners Meeting in London, 2nd July 2015, talking about 3d network models for the prediction of cyclist flows. Short version: sDNA+ allows the modelling of link level cyclist flow models based … Continue reading
sDNA has secured ESRC IAA funding (ESRC £20,000 + contributions in kind of £44,000) to work with three global transport consultancies and sustainable transport charity Sustrans on sDNA impact projects in the context of the positive active travel policy in Wales. This … Continue reading
Crispin will be presenting the latest sDNA developments at GISRUK 2015. His abstract describes (formally for the first time) the reasoning behind our continuous space algorithm. If you would like to catch up, he will be around for all three … Continue reading
New research published on theoretical network analysis Spatially localized closeness and betweenness are the bread and butter of modern spatial network analysis, and in particular, spatially localized angular analysis has become something of a de facto standard. But did you … Continue reading
