Risk-Based Filtering of Valuable Driving Situations in the Waymo Open Motion Dataset
Tim Puphal, Vipul Ramtekkar, Kenji Nishimiya
Improving automated vehicle software requires driving data rich in valuable road user interactions. In this paper, we propose a risk-based filtering approach that helps identify su…
Finding the Easy Way Through -- the Probabilistic Gap Planner for Social Robot Navigation
Malte Probst, Raphael Wenzel, Tim Puphal +4
In Social Robot Navigation, autonomous agents need to resolve many sequential interactions with other agents. State-of-the art planners can efficiently resolve the next, imminent i…
Probabilistic Collision Risk Estimation for Pedestrian Navigation
Amine Tourki, Paul Prevel, Nils Einecke +2
Intelligent devices for supporting persons with vision impairment are becoming more widespread, but they are lacking behind the advancements in intelligent driver assistant system.…
Reducing Warning Errors in Driver Support with Personalized Risk Maps
Tim Puphal, Ryohei Hirano, Takayuki Kawabuchi +2
We consider the problem of human-focused driver support. State-of-the-art personalization concepts allow to estimate parameters for vehicle control systems or driver models. Howeve…
Online and Predictive Warning System for Forced Lane Changes using Risk Maps
Tim Puphal, Benedict Flade, Malte Probst +3
The survival analysis of driving trajectories allows for holistic evaluations of car-related risks caused by collisions or curvy roads. This analysis has advantages over common Tim…
Continuous Risk Measures for Driving Support
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 longi…
Comfortable Priority Handling with Predictive Velocity Optimization for Intersection Crossings
Tim Puphal, Malte Probst, Misa Komuro +2
We address the problem of motion planning for four-way intersection crossings with right-of-ways. Road safety typically assigns liability to the follower in rear-end collisions and…
Proactive Risk Navigation System for Real-World Urban Intersections
Tim Puphal, Benedict Flade, Daan de Geus +1
We consider the problem of intelligently navigating through complex traffic. Urban situations are defined by the underlying map structure and special regulatory objects of e.g. a s…
Intersection Warning System for Occlusion Risks using Relational Local Dynamic Maps
Florian Damerow, Yuda Li, Tim Puphal +2
This work addresses the task of risk evaluation in traffic scenarios with limited observability due to restricted sensorial coverage. Here, we concentrate on intersection scenarios…
Importance Filtering with Risk Models for Complex Driving Situations
Tim Puphal, Raphael Wenzel, Benedict Flade +2
Self-driving cars face complex driving situations with a large amount of agents when moving in crowded cities. However, some of the agents are actually not influencing the behavior…
