We, Plannerstack, are “planner people” with an open source / open data perspective.
We are several companies with different specializations, but all adopting the multilayer, modular approach to passenger information systems, and a clear, layered model for feeding back transit data changes to the source (operators).
Our stated goal is to bootstrap a trip-planning ecosystem so commercial providers spring up in the apps/services and enabling (commercial) services to spring up on the other layers, e.g. multiple specialized but API and data compatible trip planning engines, and their respective hosting services).
Hereby providing the traveller with high quality and open services, ultimately decreasing the threshold and increasing the accessibility of public transport and mobility in the broadest sense.
