Researchers Arianna Burzacchi and Marco Pistore, affiliated with the Politecnico di Milano in Italy, have developed a novel simulation framework to evaluate the impacts of urban traffic regulation policies. Their work, published in the journal Transportation Research Part C: Emerging Technologies, addresses the complex challenge of assessing the direct and indirect effects of traffic policies in cities.
Urban traffic regulations are often implemented to tackle congestion, reduce emissions, and improve accessibility. However, predicting their impacts is challenging due to the intricate interplay of technical and social factors in urban mobility systems. Burzacchi and Pistore’s research leverages advances in data availability and computational power to create a model-driven, simulation-based approach for evaluating traffic policies before they are implemented.
The researchers propose a multi-layer urban mobility model that combines a physical layer, representing networks, flows, and emissions, with a social layer that captures behavioral responses to policy changes. Real-world data is used to create a baseline “as-is” scenario, while policy alternatives and behavioral assumptions are encoded as model parameters to generate multiple “what-if” scenarios. This framework allows for systematic comparison across scenarios, analyzing variations in outcomes induced by policy interventions.
The proposed approach is demonstrated through a case study that assesses the impacts of introducing broad urban traffic restriction schemes. The results show that the framework can explore alternative regulatory designs and user responses, supporting informed and anticipatory evaluation of urban traffic policies.
For the energy sector, this research offers practical applications in evaluating the impacts of traffic regulations on energy consumption and emissions. By simulating different scenarios, energy planners and policymakers can anticipate the effects of traffic policies on energy demand, helping to optimize energy infrastructure and reduce greenhouse gas emissions. Additionally, the framework can be used to assess the potential for modal shift towards more sustainable transportation options, further supporting energy and environmental goals.
