Schematic representation of transport networks
I’ve been thinking about how useful Digital Twins might first manifest themselves here in Highways England.
I’m increasingly convinced that representing the network as a schematic (e.g. simplified semi-spatial ‘tube map’ type) diagram but tying that schematic to real-world data feeds is a potentially promising route that does not require as sizeable an investment in software as other more spatial/model-based options.
This is probably stemming from having spent a fair bit of time in railway signal boxes, and seeing how schematic diagrams of the network remove a lot of unnecessary complexity from controlling train movements.
Does anyone have examples of where this kind of approach has been adopted successfully?

Not sure if this is what you refer to from your time in a signal box but If I remember correctly Network Rail used schematic 1D maps that were created back in the 80’s they were known as Quail Maps published by Trackmaps.
Not sure they will be easier than georeferenced maps to create and maintain, and the advantage of being able to exchange information between organizations will be lost.

Hi Ian, for a high-level quick-visualisation approach I think google maps + adding layers from live data might do it: https://www.google.com/earth/outreach/learn/visualize-your-data-on-a-custom-map-using-google-my-maps/. Â
I’ve seen examples which improve the visualisation using deck.gl:Â https://cloud.google.com/blog/products/maps-platform/high-performance-data-visualizations-google-maps-platform-and-deckgl
