AWS has launched a compute service that can 3D-model complex transport networks and simulate urban traffic patterns in real time across entire cities. AWS SimSpace Weaver allows customers to run simulations with more than a million entities interacting in real time and create complex environments that simulate real-world transport conditions and settings.

AWS SimSpace Weaver is a fully managed compute service that allows customers to build and run complex, large-scale spatial simulations where they can conduct experiments that closely approximate real-world systems and visualise immersive training spaces. It supports more than a million moving objects like people, cars, traffic lights, roads and other transport and environment conditions, each with their associated behaviours and properties interacting in real time.

A software development kit is provided to help build simulation applications, or use built-in integrations for third-party solutions like Unity and Unreal Engine 5. Once a customer is ready to deploy their simulation, the is set up the environment automatically and connects up to 10 low latency Amazon EC2 instances into a networked cluster, and distributes the simulation across instances.

AWS SimSpace Weaver provides a local development environment for development and testing for free on their own hardware before running simulations at scale on AWS. The local environment also uses the same APIs as AWS SimSpace Weaver so simulations can be moved to the cloud without modifying any code.

“Previously, if a customer wanted to scale up their spatial simulation, they had to balance the accuracy of the simulation with the capacity of their hardware, which limited the usefulness of what they could learn,” said Bill Vass, vice president of Technology at AWS. “AWS SimSpace Weaver removes the burden of managing simulation infrastructure, simplifying how customers run large-scale simulations and freeing them to focus on creating differentiated content and expanding access to simulation development. Whether the goal is to simulate the population of urban megacities, track logistics operations on a continental scale, or build real-world scale digital twins for smart city initiatives, AWS SimSpace Weaver empowers customers
