Our research work comparing spatial features formed by road networks of cities with different levels of planning was published in the journal Complex Systems: 

• M.T. Cirunay and R.C. Batac, Spatial Signatures of Road Network Growth for Different Levels of Global Planning, Complex Systems 30(3), 273-296, DOI:10.25088/ComplexSystems.30.3.273 (2021). 

The paper presents data and model results showing the origin of the shapes formed by the roads as they cut through space. It also presents a comparison among cities from various regions with different origins: those that are strictly planned and self-organized. Through a heuristic model, the origins of the statistical distributions of morphological features are explained. 

Michelle Cirunay is a doctoral student in physics, working on data and numerical models of road networks and other transportation channels in the urban zones. Dr. Rene Batac is an Associate Professor from the Department of Physics, College of Science, De La Salle University - Manila. The work is part of the group's efforts to study the urban zones of the Philippines, particularly the National Capital Region centered around the City of Manila.
