Lab for Innovative Infrastructure Systems

[added in 2019/12/6]

CSIS DAYS 2019 was held in front of the station of the Kashiwa Campus of the University of Tokyo, and Ogawa-san (M2) and Kita-san (M1, I) gave a presentation and a poster session.

I was nervous because it was the first time for me to present my research to the public, but I was able to exchange some opinions about my research in a friendly atmosphere from the start to the end, which was very informative. I will make use of the opinions I received in this activity in my future research. In addition, as I have many research presentations coming up in the next few weeks, I would like to continue to improve how I communicate my ideas and results to others.
I would like to thank Professor Kusakabe of the University of Tokyo for inviting us.

The 6th seminar was held on 10/25 and the 7th seminar was held on 10/30.

In the 6th seminar, (M1 students) Mr. Shimizu, Mr. Koyata, and Mr. Kita gave their presentations.
Mr. Shimizu presented the progress of his research on rainy weather and railroad congestion.
Mr. Koyata analyzed the trend of elderly people’s trips based on the Tokyo PT survey.
As a continuation of his graduation thesis, I, Kita, presented my research on the analysis of the intention to use automatic operation from the viewpoint of time value.

In the 7th seminar, (M2 students) Mr. Muro and Ms. Kawai presented their researches.
Mr. Muro presented his plan to introduce a new evaluation method in his research on the effect of Shinkansen maintenance, in addition to the difference-in-differences analysis.
Mr. Kawai presented his research on the possibility of alleviating railroad congestion in the Tokyo metropolitan area by introducing telework, and how he would analyze the results of a questionnaire survey on the intention to implement telework and the results of the Tokyo PT survey.

In fact, the second semester laboratory seminar was presented in English. I think it is a good practice for M2 and B4 students because thesis and dissertation presentations in civil and environmental engineering are given in English. It is a good opportunity for me because I nned to to prepare my overseas research presentation. Let’s improve our English skills together!

The 3rd, 4th and 5th seminars were held on October 2, October 9, and October 16, respectively.

In the 3rd seminar, (M2 students) Mr. Shiroma and Ms. Kawai gave their presentations.
Mr. Shiroma presented the direction of network analysis using electric vehicles. He aims to combine user equilibrium allocation and vehicle type selection, taking into account the charging cost of electric vehicles.
Mr. Kawai conducted a rehearsal of a web-based questionnaire asking about the intention of teleworking at satellite offices.

In the fourth lab seminar, (B4 students) Mr. Ukai and Ms. Tabuchi presented their researches.
Mr. Ukai presented the reproduction of the model used in his previous research on hunting phenomena.
Ms. Tabuchi will analyze the trip data in the Tokyo metropolitan area obtained from the Tokyo PT survey in 2008 using the Recursive Logit model and study the feasibility of introducing MaaS, etc.
The B4 students have also finalized their plans for their thesis, and it is time for them to get down to serious research work. I know that there will be many difficulties in their first research and thesis writing, but I wish them the best of luck.

In the fifth lab seminar, (M2 students) Ms. Iokura and Ms. Wang presented their papers.
Ms. Wang presented the results of the traffic survey in Ishigaki Island conducted from August to September. I am looking forward to the future analysis.
Ms. Iokura presented her study abroad in Sweden and internship in the Philippines during the past year. It was interesting to hear about the situation of universities and traffic in other countries.

As mentioned in the previous article, Dr. Ge finished his term on September 15 and returned to China.

This is a summary report of the activities of our lab members outside the university in September.

Please forgive the timeline of this report, which is back and forth from the previous one.

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 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.

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.
