Modelling the Evolution of Road Networks

This study analyzes the evolution of road networks in various cities and explores the relationship between network changes and geographic proximity. The research utilizes models and simulations to understand the patterns and processes involved. The study also highlights the importance of understanding road network changes and their impact on transportation systems.
