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
