Streetwise: Accelerating Automated Driving with advanced scenario-based safety validation
In cooperation with
Siemens, AVL, Daimler Truck
The future of Automated Driving depends on reliable safety validation of vehicles, to ensure they provide optimal safety in all traffic situations. TNO StreetWise is an advanced methodology for virtual simulation that optimally mimics real driving conditions, bringing safe Automated Driving one step closer.
With ever more advanced Automated Driving Functions (ADFs), safety validation becomes more important and complex. Given the high number of possible scenarios in which an ADF needs to be tested, virtual simulation – in addition to proving-ground and field testing – is essential to discover if safety requirements are met within a reasonable timeframe. To optimally calculate the safety risks, virtual simulations need to be based on realistic test cases and characteristics. Because TNO StreetWise uses public road driving data, the virtual test cases are representative for real-world scenarios. To ensure a safe implementation of Automated Driving (AD) technologies and to achieve a positive risk balance, TNO offers innovative risk quantification methods and scenario statistics.
Advanced safety methodology
Based on TNO’s extensive experience with vehicle safety assessment, the TNO StreetWise methodology addresses operational safety, which is an extension of functional safety (ISO26262) and safety of the intended functionality (ISO/DIS 21448:2021 SOTIF).   . After all, the automation technology takes over tasks from the human driver and should be prepared for all situations in the operational domain it is designed for (ODD). This advanced methodology is backed by a series of scientific articles.
Safer Automated Driving
Sensitivities of the tested systems are determined and quantified by combining systematic descriptions of the vehicle’s surroundings in scenarios and statistics, with systematic analysis and testing of the vehicle behaviour in such scenarios. By using statistical data from the exposure to different scenarios, one can use these simulations for risk quantification  . By doing so, our industrial clients can make significant steps towards safer Automated Driving. Also authorities responsible for type approval can use TNO StreetWise’s quantified risk estimation to determine the safety of a vehicle.
Efficient and flexible pipeline
The TNO StreetWise pipeline automatically processes your driving data into activities, scenarios, parameters and statistics. New types of scenarios can be added quickly using the underlying framework. Python algorithms running in a cloud environment ensure flexibility and scalability. The pipeline is ready for connected vehicles as well (V2X, I2V). A web GUI provides easy access to the scenario database for extraction of OpenSCENARIO test cases, including the related Euro NCAP tests. Test automation is supported through an API, as successfully demonstrated with AVL ModelConnect, Vires VTD and Siemens Simcenter PreScan. Sensitive driving data can also be processed at the client’s premises.
Accelerating safety validation
Many of our partners are working on extensive field-testing, data collection and scenario detection for Automated Driving. By collaborating and securely exchanging scenarios and statistics using Secure Multi-Party Computation (MPC), TNO manages to accelerate safety validation for our partners. At the same time, this technology allows us to fine-tune data collection campaigns and benchmark the databases of our clients.
Our clients benefit from the extensive TNO network of partners. For example, we are a certified Euro NCAP test body and were leading the development of the Cyclist-AEB test protocol (CATS). TNO is also leading the way when it comes to Euro NCAP scenario databases. The list of partners in B2B and EU projects includes most of the CCAM community (e.g., SAKURA , NTU CETRAN (Singapore), AVL , Siemens, Itility, Magna , IDIADA , BMW , Volvo , Continental , ika  , Virtual Vehicle , and Vedecom).
