A Method Using GIS Integrated Voronoi Diagrams for Commuter Rail Station Identification: A Case Study from Brasilia (Brazil)

Researchers developed a GIS-based method using Voronoi diagrams to identify optimal commuter rail station locations, applied in Brasília's Metropolitan Area. The approach integrates point density representing high-activity zones and trip-generating rate weights, resulting in a 'T' Trunk-Feeder framework that enhances multi-modal transportation planning. This model, spanning 69 km with an estimated total travel time of 62 minutes, includes 17 stations strategically linked to metro, LRT, and bus systems, prioritizing integration based on activity density. The study demonstrates how spatial analysis can optimize transit networks for efficient urban mobility.
