Invited Speakers

Prof. Bruno Monsuez

ENSTA ParisTech, France

Bruno Monsuez graduated in 1989 from Ecole Polytechnique. He received his PhD in Computer Science from the Ecole Polytechnique in 1994. He is now the Director of the Computer Science and System Engineering Department at ENSTA Paristech. His current research interests are focused on developing and enhancing hierarchical compositional mathematical models that can be used to represent hardware and software components of complex embedded systems as well as formal verification techniques that allow a cojoint verification of functional and non-functional properties of the software as well as of the hardware on which the software is expected to run.

Speech Title: Towards a Global Integrated Vehicle Motion Control: Opportunities & Challenges 

Abstract: Most of today’s terrestrial vehicles are over-actuated, combining many advanced functions that control the vehicle dynamics. This over-actuation will increase with the trend of more efficient traction engines and innovative chassis systems. Even though each system or function is developed for a particular objective, different systems may influence the same physical variable and the global vehicle dynamics. Without any global system coordination, the concurrent actions of systems may lead to unwanted interactions that compromise the potential of each system and consequently impact the global vehicle safety. This implies new requirements for the longitudinal, transverse, and vertical dynamics. However, the necessary systems that would be needed for a safe and a comfortable autonomous driving with an affordable cost remain uncertain. Our research aims to provide an extensible and modular control architecture that does not depend on a particular system combination.

Assoc. Prof. Daichi Yanagisawa

The University of Tokyo, Japan

Daichi Yanagisawa was born in Tokyo, Japan, in 1983. He received his PhD degree in aerospace engineering and Dean’s Award FY2010 (Doctoral Student) from The University of Tokyo, Japan, in 2010. He worked as an assistant professor at the College of Science, Ibaraki University, Japan, from 2011 to 2014. He is currently an associate professor at the Department of Aeronautics and Astronautics, School of Engineering, The University of Tokyo, Japan. His research interests include jamology, which is an interdisciplinary research on transportation and jamming phenomena. Especially, he focuses on pedestrian dynamics and queueing systems by applying cellular automata and queueing theory. He also conducts real experiments.

Speech Title: Managing pedestrian queueing systems: Adding a counter or providing guidance? 

Abstract: In real-world environments with multiple service counters, two common types of queueing systems are typically employed: the parallel queueing system, where each counter has its own queue, and the serpentine queueing system, where a single queue serves all counters. Although traditional queueing theory generally favors the serpentine system for its efficiency, it often overlooks the impact of delay effects. In large serpentine queues, pedestrians must walk a considerable distance from the head of the queue to the assigned counter, introducing additional latency. Furthermore, we often observe that pedestrians at the head of the queue frequently hesitate to proceed to newly available counters, largely due to limited situational awareness.
To better account for these dynamics, we developed a delay-introduced queueing model that more realistically reflects pedestrian movement and behavior. Our analysis indicates that under high arrival rates, the parallel system can outperform the serpentine system in terms of average waiting time. Additionally, when queues grow long, deploying guiding staff to reduce hesitation and improve flow at the front of the queue proves more effective than merely adding another counter. These findings underscore the importance of integrating spatial and behavioral considerations into the design of pedestrian queueing systems.
