An OpenStreetMap-Based Workflow for City-Scale Network Construction and Stress Testing in SUMO: The Seville Traffic Scenario

This preprint presents a reproducible workflow for constructing and evaluating city-scale microscopic traffic networks in SUMO using OpenStreetMap data. Applied to Seville, Spain, the methodology combines network simplification, manual correction and synthetic traffic-demand stress testing. The resulting scenario is evaluated under varying demand levels and simulation configurations, providing a robust foundation for subsequent traffic calibration, validation and urban mobility studies.
