(a) Schematic illustration of dynamical pattern formation in the LTP-reinforcement model where populated places and their inter-connections emerge naturally across the landscape. Transport links following least-cost paths across the landscape are strengthened between locations with large populations, whilst well-connected centres in turn tend to grow to a greater extent. (b,c) Schematic diagram of the LPT-reinforcement model (b) and a counterfactual, ’Geographical Determinism’ model with no reinforcement of the transport network (c).
