sDNA is world leading spatial network analysis software, compatible with both GIS and CAD and using industry standard network representation. We compute accessibility and predict flows of pedestrians, cyclists, vehicles and public transport users; these inform models of health, community cohesion, land values, town centre vitality, land use, accidents and crime. We provide a simpler alternative to transport models, particularly for sustainable transport.
To assist with the cycle planning efforts currently underway in Cardiff (Active Travel Integrated Network Map, and the review of Enfys) we are making public our current cycle model outputs. Cardiff has been sDNA’s primary test case for the development … Continue reading
In partnership with Sustrans, Crispin will be delivering two workshops on active travel planning next week at the RTPI Cymru Wales Planning Conference 2016. Under the Active Travel Act, Welsh Local Authorities are required to produce Integrated Network Maps detailing … Continue reading
sDNA was used behind the scenes to estimate ecological footprints for numerous Hay Festival alternative transport scenarios. We found that ecological impacts could be cut most by reducing international air travel and replacing private car journeys with appropriately structured bus … Continue reading
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
