ESTIMATING MATERIAL USAGE OF ROAD INFRASTRUCTURE IN US CITIES
David Quinn, John E. Fernández
This paper examines patterns that emerge in cities and proposes a link between these patterns and material us- age. This approach considers road infrastructure in cities to be a structured complex system, with properties that can be described mathematically. A general methodology is proposed and applied using data from 40 US cities. By identifying a road scaling pattern and its range of vari- ation, material usage of road infrastructure can be esti- mated based on the distance from the urban center. The results of this analysis are visualized spatially providing an intuitive way of understanding these patterns. A preliminary estimate of material consumption is made, with suggestions for future improvement.
