why this location?
Leonberg was selected by a major automotive Tier1 as an area for us to scan and bring to life some years ago. It proved to be very successful and became an essential resource for the customer, so we returned to Leonberg to expand the model to provide greater coverage of the town centre roads.
What are the key features and challenges of this location?
Leonberg is a highly populated urban environment. The road network includes complex lanes and junctions with associated signalling and traffic signs and a large variety of buildings and roadside objects. This environment leads to complex interactions between multiple road users, with pedestrians and other traffic in close proximity.
What are the special technical features of the model?
The model features a large complex urban road network with high object density. The complicated road layouts and junctions were physically and functionally modelled, with the rFpro model being supplied with matching road network maps (OpenDrive , SUMO, RD5). Traffic lights at the junctions are also all fully controllable. These features enable customers to create and control a huge variety of test conditions and scenarios.
What are the benefits for customers using this model?
The Leonberg Town model permits huge numbers of complex and potentially dangerous test scenarios to be set up in a dense urban environment with zero risk to humans or test equipment.
More generally speaking, all rFpro models permit full control and variation of the specific dynamic and environmental scenarios involved in the test. They also make it possible to easily change particular physical world objects for other varieties such as removing and replacing any (or all) of the buildings – something which is impossible using real world data alone.
In what type of applications would the Leonberg Town model be particularly useful?
It is directly applicable to all the ADAS/AD use cases among many others. Due to the low speeds, bumps and roundabouts, it also suits vehicle dynamics, including suspension tuning. Low speed start/stop urban driving is also valuable for powertrain/transmission tuning. And by introducing a real driver, representative simulation of Real Driving Emissions testing can be conducted. Furthermore, the intense driving workload in such an urban environment means it is particularly suited to HMI development.
