Introduction

What is Mobility Simulation?​

Mobility simulation (a.k.a microscopic traffic simulation) is a computer simulation of the movement of vehicles, people from one location to another. It is a key technology for understanding and optimizing transportation systems, urban planning, and logistics.

What is MOSS?​

MOSS is a GPU-accelerated large-scale open microscopic traffic simulation system.

The features of MOSS include:

  • Efficient: MOSS adopts GPU as the computational engine, which accelerates 100 times compared to existing microscopic traffic simulators, allowing rapid simulation of large-scale urban road networks.
  • Realistic: MOSS provides the cutting-edge AIGC method to generate globally available realistic OD matrices for travel demand generation and allows the user to quickly calibrate the simulation parameters to obtain realistic simulation results.
  • Open: The simulator, toolchain, and sample programs will be open-sourced on Github for community access, and we hope that more people will join in the development and application of MOSS.
