Degree Correlation of Urban Street Networks

Objective In this paper,we use the assortative coefficient to study the degree correlation of urbanstreet networks as represented by stroke intersections.It is found that some street networks demon-strate an assortative mixing pattern and others demonstrate disassortative mining pattern.The assor-tative networks would percolate easily and are resilient to breaks.This demonstrates potential forgeneral applicability to urban planning.Our conclusions are opposite to previous work and possiblereasons are discussed.
