  Understanding the dynamics of road networks has theoretical implications for
urban science and practical applications for sustainable long-term planning.
Various generative models to explain road network growth have been introduced
in the literature. We propose in this paper a systematic benchmark of such
models integrating different paradigms (spatial interactions, cost-benefit
compromises, biological network growth), focusing on the feasible space of
generated network measures. We find a quantitatively high complementarity
between the different models. This confirms the necessity of a plurality of
urban models, in line with integrative approaches to urban systems.
