Same physical state, different collective dynamics: state encodings select synchronization outcomes in language-model agents
Takahiro Ezaki, Naoto Imura, Katsuhiro Nishinari
Language-model agents act on state encodings of their environment, yet these are treated as interchangeable interfaces. Using pretrained language models, we designed a circular-syn…
From Visual to Digital: Coordination Scheduling and Its Effect on Safety and Efficiency in UAM Corridors
Akihiro Fujita, Sasinee Pruekprasert, Katsuhiro Nishinari +1
This paper explores scalable coordination strategies for urban air mobility (UAM) corridors by comparing two representative approaches. The first, inspired by visual flight rules (…
Safety-Assured Arrival Scheduling in Sequential UAM Corridor Sections under Speed and Separation Constraints
Sasinee Pruekprasert, Shinji Nakadai, Katsuhiro Nishinari
This paper presents a safety-assured arrival-scheduling framework for Urban Air Mobility (UAM) corridor operations. We propose an analytical method to compute a sufficient ETA gap…
Conflict Avoidance in Pedestrian Merging in Controlled Experiments by Variance Indicator
Jiawei Zhang, Xiaolu Jia, Sakurako Tanida +3
Pedestrian congestion at corridor intersections often originates from localized fluctuations in motion rather than from a macroscopic collapse of flow. Understanding pedestrian ins…
Effect of vehicle groups on heterogeneous disordered traffic flow
Akihito Nagahama, Nichika Asai, Claudio Feliciani +2
In heterogeneous disordered traffic, where various vehicle types operate without strict lane discipline, self-organized vehicle groups often emerge, but their influence remains unc…
Fundamental elements in the development of effective crowd control strategies
Claudio Feliciani, Daichi Yanagisawa, Katsuhiro Nishinari
In this work, we present typical challenges encountered when developing methods for controlling crowds of people (or animal swarms). We discuss which elements shall be considered a…
