Introducing Risk Shadowing For Decisive and Comfortable Behavior Planning

no code implementations20 Jul 2023 Tim Puphal, Julian Eggert

In this paper, we develop risk shadowing, a situation understanding method that allows us to go beyond single interactions by analyzing group interactions between three agents.

Considering Human Factors in Risk Maps for Robust and Foresighted Driver Warning

no code implementations6 Jun 2023 Tim Puphal, Ryohei Hirano, Malte Probst, Raphael Wenzel, Akihito Kimata

In this paper, we therefore propose a warning system that uses human states in the form of driver errors and can warn users in some cases of upcoming risks several seconds earlier than the state of the art systems not considering human factors.

Continuous Risk Measures for Driving Support

no code implementations14 Mar 2023 Julian Eggert, Tim Puphal

In this paper, we compare three different model-based risk measures by evaluating their stengths and weaknesses qualitatively and testing them quantitatively on a set of real longitudinal and intersection scenarios.

Optimization of Velocity Ramps with Survival Analysis for Intersection Merge-Ins

no code implementations13 Mar 2023 Tim Puphal, Malte Probst, Yiyang Li, Yosuke Sakamoto, Julian Eggert

We consider the problem of correct motion planning for T-intersection merge-ins of arbitrary geometry and vehicle density.

Importance Filtering with Risk Models for Complex Driving Situations

no code implementations13 Mar 2023 Tim Puphal, Raphael Wenzel, Benedict Flade, Malte Probst, Julian Eggert

Based on the results, we can further derive a novel filter architecture with multiple filter steps, for which risk models are recommended for each step, to further improve the robustness.
