Traffic Simulation Python Packages

uxsim

Vehicular traffic flow simulator in road network for Python

utdf2gmns

utdf2gmns makes Synchro traffic data easier to use and share. It converts UTDF files into GMNS, SUMO, and other interoperable formats, helping researchers and practitioners move efficiently from signal-timing data to network analysis and traffic simulation.

routerl-nightly

RouteRL is a multi-agent reinforcement learning framework for modeling and simulating the collective route choices of humans and autonomous vehicles.

fake-traffic

Internet traffic generator. Utilizes real-time google search trends by specified parameters.

agentsumo-mcp

AgentSUMO: An Agentic Framework for Interactive Simulation Scenario Generation in SUMO via Large Language Models

realtwin

ORNL’s Real-Twin project is a streamlined scenario generation tool that automatically integrates real-world traffic data to create high-fidelity digital twins for simulating the impacts of connected and automated vehicles in microsimulation environments.

diffav

Physics-informed, RL-aligned evaluation engine for autonomous driving: JAX/Flax NNX trajectory-diffusion world models on the Waymo Open Dataset, DPO and reward-guided adversarial steering toward the scenarios that break AV stacks, physics feasibility, occupancy flow, WOSAC-style realism metrics and sensor simulation.

unsim

Traffic simulation with Autodiff

micro-traffic-sim

gRPC server for MicroTrafficSim

routerl

RouteRL is a multi-agent reinforcement learning framework for modeling and simulating the collective route choices of humans and autonomous vehicles.

macro-traffic-sim

gRPC server for MacroTrafficSim

routerlurb

RouteRL is a multi-agent reinforcement learning framework for modeling and simulating the collective route choices of humans and autonomous vehicles.

gui4gmns

AI-guided, offline-capable dashboards for GMNS traffic networks (DTALite / TAPLite / Dynamic ODME / DLSim): GMNS run folder in, one self-contained dashboard.html out. Cross-platform successor to the NEXTA GUI.
