SESAM: Mobility Simulations in the Cloud

SESAM is a collaborative platform for building digital twins and mobility simulations in the cloud. Benefit from ready-to-use scenarios or create your own.
Run your simulations on our high-performance cluster to get your simulation results faster.

Cloud Native

Get started quickly in a ready-to-use and high-performance cloud environment - no local software installation needed.

Easy Building

Building a simulation scenario is easy with a user interface that is simple, but also powerful for beginners and experts.

Beyond Cars

Simulate not only passenger cars, but also multimodal traffic with pedestrians, bicycles, motorcycles, trucks, busses, trains, ...

Map Data

We rely on OpenStreetMap to get you started quickly with a world-wide coverage of map data for road networks.


SESAM offers a public REST API for an easy integration of a mobility simulation in existing applications and services.

Visualize Results

Turn numbers into visuals and gain insights into travel times, waiting times, traffic densities and much more.

Scenario Management

Organize your scenarios, simulation parameters and simulation results in our cloud-based workspace.

Seamless Collaboration

Share your scenarios and simulation results with colleagues, customers or other stakeholders within your project.

Trusted Simulation Engine

SESAM is built on top of the proven mobility simulation engine Eclipse SUMO to deliver detailed and realistic simulations.


Build a simulation scenario with just a few clicks

With SESAM you can build large-scale simulation scenarios in an easy to use web interface within a few minutes time. Simply select the simulation area within a map, add traffic demand patterns (e.g. vehicles, bicycles or pedestrians) and let SESAM do the rest for you. After creation, the new scenario will be stored in your personal workspace.

Unleash the power of Eclipse SUMO

Run simulations from your workspace on our cluster of high-performance computing nodes. SESAM uses the Eclipse SUMO mobility simulation toolkit for the computation of the dynamic models for all agents in your scenario. Trigger multiple simulation runs with varying parameters to gain more insights on the sensitivity of your results.


Get more insights from your simulation results

Quickly conduct what-if mobility simulations and analyze your results visually by turning raw numbers into comprehensive map overlays. Benefit from automatically generated before/after comparisons - ready to be used in reports. Share your scenario, results and key figures with your team, your customers or other stakeholders within your project.
