ABSTRACT Velocity Occupancy Space (VOS) is an algorithm used to perform real-time moving obstacle avoidance for Unmanned Ground Vehicles (UGVs). Pedestrian safety and comfort must be ensured by the guidance algorithm when UGVs operate near pedestrians. Studies on human interactions are used to formulate desired behavior of the UGV as it avoids people. Then, VOS is enhanced with improved avoidan...

Safety, security, and comfort of pedestrian crowds during large gatherings are heavily influenced by the layout of the underlying environment. This work presents a systematic agent-based simulation approach to appraise and optimize the layout of a pedestrian environment in order to maximize safety, security, and comfort. The performance of the approach is demonstrated based on annual “Salone de...

The understanding of crowd behaviour in semi-confined spaces is an important part of the design of new pedestrian facilities, for major layout modifications to existing areas and for the daily management of sites subject to crowd traffic. Conventional manual measurement techniques are not suitable for comprehensive data collection of patterns of site occupation and movement. Real-time monitorin...

The paper presents an emerging issue of fine-grained pedestrian action recognition that induces an advanced pre-crush safety to estimate a pedestrian intention in advance. The fine-grained pedestrian actions include visually slight differences (e.g., walking straight and crossing), which are difficult to distinguish from each other. It is believed that the fine-grained action recognition induce...
