Active mobility, such as cycling and walking, is an important part of a sustainable transportation system in the city of tomorrow. However, traffic accidents, especially those involving vehicles, are the number one cause of death worldwide for children and young adults [1]. Road safety is an essential key to successfully promoting active mobility.

Thus, the proposed workshop will explore the road safety challenges for cyclists, pedestrians, and e-scooter drivers (i.e., vulnerable road users (VRU)) by sensing human activity, developing new technical applications, ubiquitous sensors, and AI algorithms to motivate to cycle and walk and to create a sustainable transportation system in the city of tomorrow. We invite to this workshop unique contributions addressing these challenges. UbiComp4VRU 2025 aims to facilitate collaboration among research groups working on these topics.

Topics of interests include, but are not limited to the following areas:

• Human Activity Recognition of VRUs
• Machine learning and context modeling for pedestrians and bicyclists
• Ubiquitous, pervasive, and wearable computing
• Technical infrastructure measures
• Targeted training programs for cyclists and pedestrians
• Sensing and modeling of VRU behavior
• Intention, trajectory, and behavior prediction of VRUs
• Novel applications, sensors, and wearable devices motivating to cycle or walk
• Mobile data measurement and collection platforms for active mobility
• Theory, experimental design, computational models, algorithms, and evolutionary investigation in VRU safety
• Active activity representations and signal characteristics
• Legal, ethical, psychological, and normative aspects of active mobility, VRU safety, and sustainable transportation systems
• Privacy issues
• Development and embedding of new sensors and devices for VRUs
• Active mobility (e.g., walking and cycling)
• Resilient sustainable environment
• Communication and sensing
• Car2VRU architectures
• Car2VRU applications and use cases
• Car2X, Car2VRU (Car2P, Car2B) communications
• Analysis of latency, overhead and message frequencies for Car2VRU communication
• Localization, trajectory prediction, and GNSS improvements
• Ultra-reliable and low-latency communications (URLLC)
• Mobile edge computing (MEC)
