Who should consider using METS-R?

METS-R SIM provides a versatile simulation framework that supports a wide range of mobility and control applications. In standalone mode, it can simulate city-scale mobility services with electric vehicles, including ride-hailing and bus operations. In high-performance computing (HPC) mode, it supports integration with cloud-based control and Kafka data streams, while also enabling parallel execution for large-scale simulation and data generation. METS-R SIM is currently under active development to further enhance these capabilities and support co-simulation with CARLA. Its operating modes can support applications such as:

• city-scale electric mobility service simulation

• cloud-based fleet control and coordination

• eco-routing and demand-adaptive transit scheduling

• large-scale parallel data generation

• co-simulation with CARLA for richer cyber-physical experiments

Running mode	Description	Applications	Target users
Standalone	This mode supports first-come-first-serve ridehailing and static transit. It requires only the simulation module.	Verifying infrastructure (i.e., charging stations, bus stops) and service fleet size design	Planners, policymakers
Synchronized (HPC)	The simulation waits until the HPC module https://github.com/umnilab/METS-R_HPC sends a tick, enabling co-simulation and rigorous tests of cloud-based operational algorithms.	Optimizing/verifying advanced operational algorithms	Researchers, service providers
