Adopting open transport data standards – a map of current GTFS availability

Watching the GTFS continue to grow throughout the world over the past few years has been a fun journey. Originally a partnership between Portland (TriMet) and Google to get transit data on Google Maps way back in 2006 – now a huge global standard that helps many people move about in their home cities as well as on their travels. I’ve attempted to map the coverage of GTFS on the following quick map. So many apps and research efforts benefit from adopting this global standard – impressive to see many cities providing open real-time transport data as well. The GTFS community are working hard to transfer this standard for more informal networks in developing world (note the focus on the global ‘West’), as well as changes in urban mobility (such as on-demand transport).

Highlights from SIGGRAPH Asia 2018, Tokyo

I had the great pleasure of attending SIGGRAPH Asia in Tokyo this year. SIGGRAPH is the annual conference on computer graphics convened by the ACM SIGGRAPH organisation. The first SIGGRAPH conference was in 1974, and there are now many, many chapters in the world. The conference is attended by tens of thousands of computer professionals.

SIGGRAPH Asia was certainly very impressive as a first time attendee. While the conference has strong roots in computer graphics – these attract a crowd annd topics from film-making, animation, art, interactive technologies (AR/VR/XR), internet of things, haptics and so forth. For me, it was really exciting and inspiring to see these applications and to think about how they can also be applied to solve problems in the built environment field – to architecture, urban design, planning and geography. While initially daunting, it was found there were many things here that represent future directions for built environment work. I have summarised six of my favourite displays, demos, briefs and presentations from SIGGRAPH Asia this year. I really look forward to next year in Brisbane!

Technical Brief – Automatic Site Selection of Cultural Venues

The authors presented a novel approach to support site selection of culture venues using machine learning. These techniques are a very unique approach to many of the traditional GIS and spatial analysis approaches done by planners.

Technical Brief – Automatic route planning for GPS art generation

The authors presented a novel approach for the automated route generation of GPS artwork, which is described by leaving virtual traces on digital maps. This is quite interesting as it also created a new-purpose form of routing algorithm to try and draw pictures.

MR360: Immersive Mixed Reality with Live 360 degree video

DreamFlux Presented MR360 Live, a new way to present 3D virtual objects into live streamed 360 videos. This provides the illustion of interacting with objects in the video. They presented applications of augmented ‘teleportation’. The users can add and interact with super realistic digital objects in the video and create their own augmented / mixed reality world. Amazing potential for urban design, co-design, and community engagement!

Art Plunge

Art Plunge is a virtual reality experience where you can get the feeling of being transported to the inner worlds of famous paintings. The authors have created VR-interpretations of works like Mona Lisa, Starry Night and the Birth of Venus.

The authors explore the concept of what a painting could be in virtual reality, and how different boundaries are blurred in the process: Boundaries between our interpretation and the original painting, between technology and artistry and between now and then.

Pac in Town

“The player is the star” was Bandai Namco’s futuristic vision for mixed reality entertainment. At SIGGRAPH, users were able to test out the collaborative augmented reality PacMan game. While it wasn’t 100% refined, you cannot argue when playing this you saw a glimpse of the future – and great to share an AR view with others.

Trajectile Command

Trajectile Command is a free WebVR game. WebVR is an emerging technology standard which allows Virtual Reality experiences to be accessed directly from a web browser. The advantages of WebVRover traditional VR experiences is that a user can access content without requiring any third party apps. Trajectile Command is similar in philosophy to free flash games, except in VR. In this capacity Trajectile Command is one of the first of its kind. The game can be played at www.micosmo.com/trajectilecommand. It was not so long ago I was personally experimenting with WebVR of cities, so great to see this kind of stuff is still progressing – and becoming more interactive!

Experiments with DeckGL – Population and Transport in Sydney

Deck.gl is a WebGL-powered framework for visual exploratory data analysis of large datasets.

Below are some works in progress of Deck.gl powering analysis of GTFS-Realtime data for Sydney (the information about where exactly the whole network is at any one time) as well as population and employment projections for Sydney. While the framework is reasonably straightforward to use – the process to get the data from the feeds to be read into the framework was quite a burden (I will try and push these to GitHub if anyone asks).. Now to get them online ; and with more buttons! 🙂

DeckGL Flows – Sydney GTFS Test – Oliver Lock May 2018 from Oliver Lock on Vimeo.

An example including buildings generated from cutting mesh blocks out of the road network, with a height based on population density.This provides us with images that look more like the real city, rather than flows running through empty space.

Zoomed out, with buildings, you can see the incredible organic development patterns of Sydney and how transport supports fringe areas.

Population density explorer – so much potential using this hex bin / pipe method to show information. Here we can get very fast renderings for the population density of the whole country. Providing toggles / buttons you could switch between variables (population / employment) as well as past data and future forecasts.
