Title
How Land Use Shapes the Evolution of Road Networks
Abstract
The present research develops an agent-based model to treat the organization, growth, and contraction of network elements. The components model travel demand, revenue, cost, and investment. Revenue earned by links in excess of maintenance costs is invested on the link to until all revenue is consumed. After upgrading (or downgrading) each link in the network, the time period is incremented and the whole process is repeated until an equilibrium is reached or it is clear that it cannot be achieved. The model is tested with three alternative land use patterns: uniform, random, and bell-shaped, to test the effects of land use on resulting network patterns. It is found that similar, but not identical, equilibrium hierarchical networks result in all cases, with the bell-shaped network, with a CBD, having higher level roads concentrated in a belt around the CBD, while the other networks are less concentrated
