Multi-modeling the morphogenesis of transportation networks

International audience; This research introduces a multi-modeling approach to the growth of transportation networks. More precisely, we imple- ment and compare several models, based on biological net- work growth, cost-benefit rules, and gravity potential break- down. The resulting multi-modeling framework is calibrated on observed topological data for the European road network. We show that different heuristics are complementary to cover the feasible topological space and that all are necessary to approach existing configurations, what suggests the superpo- sition of corresponding processes in territorial systems.
