SUMO traffic integrated in DYNA4

  • Integration of stochastic traffic from SUMO providing interaction with vehicles, pedestrians and traffic lights
  • SUMO is a free open-source traffic simulator by DLR
  • GUI based configuration in DYNA4
  • Combination of deterministic DYNA4 scenarios with stochastic SUMO traffic
  • Virtual test driving natively on OpenDRIVE road
  • Great 3D visualization of the entire scenario in DYNA4
