A review of the structure of street networks

TL;DR

This paper reviews various measures of street network structure, highlighting their practical relevance, regional differences, and the challenges faced in understanding the geometric and topological diversity of street networks worldwide.

Contribution

It systematically surveys existing measures of street network structure, assesses their practical relevance, and identifies open research challenges related to heterogeneity across regions and eras.

Findings

Measures vary significantly across regions and eras

Street networks exhibit substantial geometric and topological heterogeneity

Open challenges remain in understanding street network complexity

Abstract

We review measures of street network structure proposed in the recent literature, establish their relevance to practice, and identify open challenges facing researchers. These measures' empirical values vary substantially across world regions and development eras, indicating street networks' geometric and topological heterogeneity.
