AgentSUMO: An Agentic Framework for Interactive Simulation Scenario Generation in SUMO via Large Language Models
Minwoo Jeong, Jeeyun Chang, Yoonjin Yoon

TL;DR
AgentSUMO leverages large language models to enable non-experts to generate complex, realistic traffic simulation scenarios in SUMO through an interactive, adaptive framework that interprets high-level objectives.
Contribution
This work introduces AgentSUMO, a novel agentic framework that interprets user intents and generates executable simulation scenarios in SUMO, bridging the gap between policy goals and technical simulation setup.
Findings
Improved traffic flow metrics in Seoul and Manhattan simulations.
Enhanced accessibility for non-expert users in urban traffic simulation.
Effective translation of high-level objectives into detailed simulation plans.
Abstract
The growing complexity of urban mobility systems has made traffic simulation indispensable for evidence-based transportation planning and policy evaluation. However, despite the analytical capabilities of platforms such as the Simulation of Urban MObility (SUMO), their application remains largely confined to domain experts. Developing realistic simulation scenarios requires expertise in network construction, origin-destination modeling, and parameter configuration for policy experimentation, creating substantial barriers for non-expert users such as policymakers, urban planners, and city officials. Moreover, the requests expressed by these users are often incomplete and abstract-typically articulated as high-level objectives, which are not well aligned with the imperative, sequential workflows employed in existing language-model-based simulation frameworks. To address these challenges,…
