I released a new Julia library, OptimalTransportNetworks.jl (https://github.com/OptimalTransportNetworks): https://sebkrantz.github.io/Rblog/2024/09/22/introducing-optimaltransportnetworks-jl-optimal-transport-networks-in-spatial-equilibrium/

The software uses duality principles to optimize over the space of networks, nesting an optimal flows problem and a neoclassical general-equilibrium trade model into a global network design problem to derive the optimal (welfare maximizing) transport network (extension) from any primitive set of economic fundamentals.

-> A 'generative' spatial economic model for network planning

@sebkrantz I have friends working on this similar thing, will share this to them. Thanks for sharing.

@kkavee cool, thanks. Not exactly what this is about, but multimodal transport is certainly interesting. Lots of work to do at the intersection of transport and economics for sure.
