The main theme of the document is urban mobility-related emissions modeling using the METROPOLIS multi-agent system for Riyadh city.
The study aims to assess and reduce the environmental impact of emissions in rapidly growing cities. Key findings include the development of a model that evaluates emissions and their environmental impact using a dynamic traffic simulator. The model is calibrated to reproduce observed congestion patterns and validated through day-to-day dynamics. The document offers a methodological framework for assessing scenarios in Riyadh.
