Community core detection in transportation networks

TL;DR

This paper investigates methods for detecting stable community structures in transportation networks, focusing on commuter trip distributions and land-use patterns to aid transport planning.

Contribution

It introduces an analysis of community core detection and stability in transportation networks, emphasizing the role of land-use distribution.

Findings

Community cores are linked to land-use patterns.

Community stability varies with perturbations in trip data.

Methodology aids transport planning decisions.

Abstract

This work analyses methods for the identification and the stability under perturbation of a territorial community structure with specific reference to transportation networks. We considered networks of commuters for a city and an insular region. In both cases, we have studied the distribution of commuters' trips (i.e., home-to-work trips and viceversa). The identification and stability of the communities' cores are linked to the land-use distribution within the zone system, and therefore their proper definition may be useful to transport planners.
