Keynote: Simulating and modelling traffic: What are we trying to achieve?
summary
Simulation work uses SUMO with video trajectory extraction and automated calibration to test concrete changes: a bicycle simulator is built in Wuppertal, traffic signals and routing algorithms are tested, and open data plus shared code accelerates repeatable studies. Modal shift yields quantified gains: about 139 g CO2 per person‑km saved when trips move from car to bike, estimated as 5.6 Mt CO2 and €54.8B in 2017. A field experiment with countdown signals increasing red‑light running shows simulations must validate behavioral effects, not just flows.
