November 26, 2023 We had many visitors at our open campus. Thank you very much!

After that, we held a sushi seminar:)

October 28-29, 2023. We went camping in Susono for a lab trip. There was a thunderstorm at midnight, but we enjoyed hot spring and BBQ!

September 26, 2023, B4 Supervisory Student, Mr. Nicika Asai presented "Effects of the Ratio of Respective Vehicle Types in Mixed Traffic on Traffic Flow" at the Interim Graduation Research Presentation of our Management Science and Social Informatics Program.

Good work!

September 25, 2023, The paper "Potential risk of driving performance under combined conditions of taking second-generation antihistamines and attending calls using a hands-free function" was accepted for publication in Traffic Injury Prevention.

This research is based on an academic collaboration agreement between Hoshi University and the University of Electro-Communications. 

September 19, 2023, we hosted the first "Seminar on Heterosocial Systems" and invited Dr. Jia Xiaolu.

Dr. Xiaolu Jia introduced the discrepancy between physical and subjective congestion observed in pedestrian traffic flow with various attributes.

Thank you very much for your lecture!

September 9, 2023, Nagahama presented "Research on chaotic vehicular traffic-perspectives of data science, physics, and traffic engineering-" at the 10th UEC Seminar in ASEAN.

Nagahama introduced various approaches of research on traffic in developing countries to ASEAN researchers/students with various research backgrounds.

September 9, 2023, article "Learning and predicting the unknown class using evidential deep learning" was published in Scientific Reports.

Access to printed ver.: https://www.nature.com/articles/s41598-023-40649-w

June 23, 2023 "Optimizing Evidential Deep Learning Generators for Modeling Vehicular Traffic Patterns in Developing Countries" was presented at the International Symposium on Scheduling 2023.

Algorithms for generating various types of vehicles in a traffic simulator for the mixed traffic were studied. By generating vehicles based on real traffic trends, we aim to reproduce physical phenomena unique to mixed traffic that cannot be analyzed with macroscopic traffic simulators.

June 23, 2023, Mr. Seigo Takahashi, a master's student with whom we are collaborating, presented "Effect of Supplier Selection of Electric Moped Scooters Sharing Services for Material-Based Greenhouse Gas Emissions and Costs" at International Symposium on Scheduling 2023.

This presentation received The Encouragement Award in International Symposium on Scheduling for this presentation. Congratulations!

March 2023, Ms. Shiori Fujimatsu, a supervised student, received the Megurokai Award for her bachelor thesis. 

This research examined road surface design that suppresses driving speed not in a single landscape environment, but in a variety of landscapes or changing landscapes.

Congraturations!

December 9, 2022 A supervised student gave a poster presentation at The 4th ASEAN - UEC Workshop on Informatics and Engineering.

In order to avoid "inappropriate system use based on distrust" in automated systems, we measured the effects of additional information presentation and an interface for pointing out system malfunctions on the sense of trust. In particular, this study focused on automated driving and driver assistance, and found that information presentation and interfaces increase trust.

December 9, 2022 Poster presentation at The 4th ASEAN - UEC Workshop on Informatics and Engineering.

In road traffic in emerging countries, multiple vehicles have relations through acceleration and deceleration. In this study, we analyzed such relations or connections between "randomized and grouped vehicles" based on graph theory, and suggested that the connection between these areas might be weak.

I was invited to give an invited lecture at Traffic and Granular Flow 2022 (IIT Delhi) on October 16, 2022.

I discussed the significance of studying road traffic in emerging countries, where a variety of vehicles are moving in all directions, in relation to the maintenance of diversity in society.

Oral presentation at Traffic and Granular Flow 2022 (IIT Delhi), October 16, 2022.

This research evaluated a prototype vehicle generation algorithm used to simulate emerging road traffic.

By modifying a vehicle generation model, we aim to elucidate the behavior of emerging road traffic more accurately.

June 8, 2022 Poster presentation at 2022 IEEE Conference on Cognitive and Computational Aspects of Situation Management.

This is a pilot study of the effects of the urban road environment (especially scattered garbage and blaring horns) on driving behavior.
