The second semester of lab activities has begun.
[9/25]
The second semester of laboratory activities started last week.
The first lab seminar was held on September 18, and the second lab seminar was held on September 25.
In the first seminar, (M1 students) Mr. Shimizu, Mr. Koyata, and Mr. Kita gave their presentations.
Mr. Shimizu presented the progress of his research on rainfall and train delays.
Mr. Koyata presented the results of his basic analysis of elderly people’s behavior based on the results of the Tokyo PT survey in 2008.
Mr. Kita presented the results of his previous research on the analysis of determinants of intention to use a fully automated ride-sharing system, which was submitted to HKSTS.
In the second seminar, (M2 students) Mr. Ogawa and Mr. Muro gave presentations.
Mr. Ogawa is working on short-term prediction of traffic conditions in the central area of Kamakura city using a recurrent neural network.
Mr. Muro is analyzing the effect of transportation infrastructure improvement using causal inference.
Both of them reported the progress of their research based on the reflections from the critiques they received from other laboratories in the summer seminar.
Ms. Salsa has graduated and said goodbye to the lab…
Mr. Ge, a researcher, finished his term and went back to China…
I would like to express my gratitude to all the seniors who have been with us since last year. Thank you very much.
Although the number of students in our laboratory has decreased, I think it will become noisy and lively again with the addition of Ms. Iokura!
I am sure it will get harder as we will be busy with our graduation theses and master’s theses, but that’s why we should all have fun and work hard!
Behaviour Modelling Summer School 2019
[2019/9/21-23]
The Summer School of Behavioral Modeling at the University of Tokyo was held again this year. This year, six members of Fukuda Lab, including (M2 students) Ms. Wang, Mr. Shimizu (M1), Mr. Koyata, Mr. Kita, and (B4 students) Ms. Tabuchi and Mr. Ukai, participated in the summer school. We used the Mixed Logit model to analyze the residential inclinations of Yokohama residents’ trips to and from their homes for commuting. As for my personal impression, I was able to gain a better understanding of the fundamentals of the logit model through the experience of constructing a model from scratch and conducting the analysis myself, given the limitations of the information available in the data and the number of samples. Moreover, I was able to spend a week with my new lab members who joined this year, and we had a chance to get to know each other better. I would like to express my gratitude to the members of Hato Laboratory at the University of Tokyo for their smooth operation and communication as the organizer.

We went to Yaeyama islands for a tourism survey!
[2019/08/16-20]
We participated in a survey on tourism in Ishigaki Island jointly with Kamiya Laboratory of Ryukyu University and Chuo Construction Consultants. The purpose of this survey was to investigate the flow of tourists visiting Ishigaki Island and surrounding remote islands during August and September. (M1 student) Ms. Wang and (B4 student) Ms. Tabuchi participated from our laboratory.
The survey was conducted on Ishigaki Island and the surrounding islands (Iriomote, Hateruma, and Taketomi). Iriomote Island is known for the Iriomote wildcat, and the number of traffic accidents involving wild animals including Iriomote wildcat has been increasing in recent years. In this study, Wi-fi packet sensors were installed at major tourist spots, terminals, and near the airport to investigate the movements of tourists visiting Ishigaki Island by collecting information sent from Wi-Fi on mobile devices such as smartphones owned by tourists. We also conducted a traffic survey by installing Bluetooth packet sensors along roads in Iriomote Island for the purpose of investigating the status of traffic accidents in Iriomote Island. In order to observe the speed of the traveling cars, we installed Bluetooth packet sensors along the roads of Iriomote Island, which can also observe the speed of passing cars. We also conducted a bus boarding and alighting survey and questionnaire survey in order to investigate the diffusion of the transfer guide service by Google’s application.

2019 TSU Summer Seminar
[2019/08/24~26]
Sorry for the late update.
The TSU joint summer seminar was held at Ookayama campus of Tokyo Tech. Prof. Fukuda, (M2 students) Mr. Shiroma, Mr. Ogawa, Mr. Kawai, Mr. Muro, and (M1 student) Ms. Wang gave their presentations. Prof. Kamiya and Dr. Gabe from University of the Ryukyus, who are collaborating with Prof. Fukuda in his research, also made a presentation. The presentations by the seniors generated many opinions and questions from the professors and students of other laboratories, and produced lively discussions. The opinions of the fixed members of a laboratory tend to be biased, so the suggestions and opinions obtained in the laboratory seminar are very valuable. We, M1 and B4 students, who listened to the presentations by seniors in other laboratories, also gained many hints for our own research in the future. Let’s make the most of this opportunity and continue to work hard on our own research in the second half of the 2019 academic year.
I am sorry for the delay in introducing this, but the person in charge of updating the website has changed from Ms. Kawai to (M1) Kita starting this month. Thank you for your cooperation.

Master’s thesis presentation & Summer party
[August 7, 2019]
Today, the Master’s thesis presentation by students admitted in the fall was held, and Ms. Salsabila (M2 student) presented from our laboratory.
She compared the systems and results of TOD (Transit Oriented Development) on residential land prices in the Tokyo metropolitan area using several models. During the question-and-answer session, the professors had a lively discussion about the impact on land prices in neighboring areas and the interpretation of the model’s parameter values.
Mr. Ge, Mr. Dantuji, and Ms. Salsabila, will leave our laboratory next fall, and Prof. Fukuda gave us a few words each about their research life so far. To those who are leaving our laboratory, thank you very much for everything you have done for us in our laboratory!
Master’s thesis submitted by Ms. Salsabila
[2019/07/24]
Today, (M2 student) Ms. Salsabila completed and submitted her master’s thesis.
Ms. Salsabila used several models to compare the accuracy and results of the impact of TOD (Transit Oriented Development) on residential land prices in the Tokyo metropolitan area. Using the MMMM (Multiple Menbership Multilevel Model), a type of regression model that takes into account multiple memberships of rail lines, she found that the value and accessibility of neighboring areas and the distance from the central business district and subcenter significantly affect land prices. The model also shows that land values are higher along railroad lines extending to the southwest of Tokyo.
The 12th and 13th lab seminars
[2019/07/17 & 07/22]
In the 12th and 13th seminar, (M1 students) Mr. Shimizu, Mr. Koyata, Mr. Kita, and Ms. Wang and (D1 student) Mr. Azarel gave their presentations.
Mr. Shimizu and Mr. Koyata presented their research plans and reviewed related research on the analysis of train delays and mobility for the elderly, respectively.
Mr. Kita presented the results of a discrete choice model of the determinants of intention to use a fully automated ride-sharing system, based on the results of an SP survey. He is currently using a Panel Mixed Ordered Logit model for more detailed estimation than before.
Ms. Wang presented a study of traffic accidents caused by tourist excursions and contact between endangered animals and cars, which will be conducted using Bluetooth and Wi-Fi packet sensors, and the concept of using the data for research analysis.
Mr. Azarel presented a literature review on Mobility As A Service (MaaS) and a definition of MaaS for future research.
The 10th and 11th lab seminar!
[July 4 and 12, 2019]
(M2 students) Mr. Ogawa, Mr. Shiroma, Mr. Muro, and Mr. Kawai presented in the 10th and 11th lab seminar.
Mr. Ogawa presented his research on short-term prediction of traffic conditions using recurrent neural networks, from the overview to the analysis results, using data from the central area of Kamakura City.
Mr. Shiroma presented the concept of his research on the analysis of users’ traffic preferences associated with the spread of electric vehicles (EVs).
Mr. Muro presented a review of similar studies and a future research plan on a method to evaluate the effect of transportation infrastructure development using causal inference.
Mr. Kawai presented the concept of a study on office use intention under the assumption that workers can choose the location of their workplaces due to the spread of teleworking, and its application to transportation demand forecasting, as well as the results of basic model estimation.
In the Q&A session, many participants commented on the need to provide a convincing explanation of the purpose and background of the research. I have decided to devote myself to my research even more than before.
Final presentation of doctoral dissertation (Mr. Dantsuji)
[2019/07/03]
The final presentation of the doctoral program was held today, and Mr. Dantsuji (D3 student) presented from our laboratory.
Mr. Dantsuji gave a presentation titled “Modeling and Optimizing Bi-modal Urban Transportation Systems: A Macroscopic Approach”, using 3D-MFD (Macroscopic Fundamental Diagram). Optimization modeling of two modes of transportation, bus and car, was conducted using the 3D-MFD (Macroscopic Fundamental Diagram) as an example for the central Tokyo area.
The professors provided a wide range of active opinions on the model and its purpose.
The 9th and 10th basic seminar
[2019/07/02 & 07/09]
In the 9th basic seminar, (M1) Mr. Kita was in charge of this seminar and taught how to view, edit, and analyze geospatial information, including how to operate QGIS, a free software, and how to create maps and analyze spatial attributes by coding in R. He prepared materials in considerable detail, ranging from ordinary cartography to the creation of colopres maps. This will be useful for research analysis and illustrations for external presentations.
The 10th seminar was led by Ms. Wang (M1), and covered topics ranging from analysis of large-scale data using R to methods for analyzing spatial statistical data.
This is the end of this year’s basic seminar. The materials used in the seminar will be uploaded on the website as soon as they are ready.
