Lab for Innovative Infrastructure Systems

Salsa-sann, a project researcher in the Fukuda Lab, have made a report for kick off event of 3DTraffic Project in Bangkok. Below is the report. 

I am Salsa, a Project Researcher in the Fukuda Lab.

Currently, Prof. Fukuda, Dr. Fujiwara, Krittanai, and I are involved in a project called 3DTraffic SATREPS Project. The project is a collaborative research project between research institutions in Japan and Thailand and aims to reduce the greenhouse gas emissions in Bangkok through the improvement of traffic control.

On Monday, May 20, 2025, we had some events to initiate our project at Chulalongkorn University, Bangkok, Thailand. The events started with a Joint Coordination Committee meeting in the morning, followed by 3DTraffic Lab Opening Ceremony, the Kick-off Symposium, and ended with a reception dinner. The Kick-off Symposium was open for the general public to attend, and the event was conducted hybrid style (on-site and online webinar participation), so I was able to attend the webinar from my home in Tokyo.

The symposium started with remarks from Prof. Kasem Choocharukul of Chulalongkorn University and Mr. Haruka Ozawa from the Embassy of Japan in Thailand. As the Project Investigator of 3DTraffic, Prof. Daisuke Fukuda also elaborated on the overview of 3DTraffic project. We were also honored to have Distinguished Professor Yoshitsugu Hayashi (Tokaigakuen University) delivered a keynote lecture at our event. As the project leader of the previous SATREPS project, which also took Bangkok as a case study, we gained a lot of insights from Prof. Hayashi’s speech about Bangkok’s historical to present mobility and urban conditions, also how the Quality of Life and CO2 emissions can be improved through the transformation of city structure and optimizing QoL-MaaS scenario, advices that came from his project.

Each working group also had the chance to present their study plans and what they are aiming to achieve within the 5-year period of this project. A panel discussion session was held, with Prof. Yoshitsugu Hayashi, Prof. Takashi Oguchi, Prof. Sorawit Narupiti, and Prof. Kasem Choocharukul as panelists and Mr. Yoshihisa Asada as the moderator. 3 main topics guided the discussion, and the experts gave their invaluable opinions about the legacies that can be utilized in the project, the kind of output that the project shall disseminate, and the project’s prospect in developing human resources. The event was closed with a remark from Prof. Sorawit.

We are grateful that despite their busy schedule, many people participated in the event since the morning, including various Thai government agencies involved in transportation planning and traffic management in Bangkok, representatives from Japanese government agencies, and researchers from various institutions who are members of the 3DTraffic project. We are looking forward to having a good collaboration with everyone, and we are committed to giving our best to reach the goals in our project!

Today, a TSU seminar on transportation big data was held on campus by Prof. Charisma F. Choudhury.

Dr. Charisma is an associate professor at the University of Leeds (UoL), UK, where she leads the Choice Modelling Research Group and works primarily on choice models. The car driving behavioral model developed as part of her thesis has been implemented in major commercial traffic simulation tools such as AIMSUN and VISSIM.

In today’s lecture, he used anonymous big data such as cell phone location data and call log data as case studies to propose frameworks such as latent demographic models, compare them with existing data (e.g., questionnaire-based surveys), and analyze traffic conditions by combining them with machine learning. She also explained about traffic analysis in combination with machine learning.

The following is a short summary of the lecture that was presented at the 37th TSU Seminar.

Presentation Title: Travel behaviour modelling using emerging big data sources

Date: August 22th (Thu.) 2019

Time: 15:00 -16:30

Venue: Tokyo Tech. Ookayama Campus, Multi-Purpose Room, 1st Floor, Midorigaoka Buidling #6

        (https://www.titech.ac.jp/english/maps/ookayama/midorigaoka.html)

Speaker: Charisma F. Choudhury, PhD, FHEA

                Deputy Director, Choice Modelling Centre Associate Professor,

                Institute for Transport Studies & School of Civil Engineering

                University of Leeds, Leeds, UK

Presentation Abstract:

Over the last decade, passively generated big data sources have emerged as a very promising source of activity and mobility information.  Examples include GPS, mobile phone, smartcard and social media data, online browsing and purchase records of tickets, cars/bikes, residential properties, etc.  However, due to the coarse spatial and temporal resolution, sampling and privacy issues, these data sources are yet to be used for mainstream travel behaviour modelling. The presentation will include four case studies on how these big data sources can be used for mainstream transport modelling – each focusing on a unique limitation of the big data. Case study 1 proposes a ‘latent demographic model’ framework to utilize large scale anonymous data from mobile phones and applies it in the context of trip generation modelling in Switzerland. Case study 2 proposes an application of the ‘broad choice modelling’ framework to deal with the coarse spatio-temporal resolution of the mobile phone data in the context of route choice modelling using call detail record data from Senegal. Case study 3 contrasts the performances of mobile phone and GPS data in the context of departure time choice modelling in Switzerland. Case study 4 proposes a methodology to fuse the household survey and mobile phone data to get the best out of both worlds.  The presentation will conclude by summarizing the insights gained from these studies and an overview of some other ongoing research.

A mini-seminar on the Probe Person survey application was held on campus by Prof. Yusak Susilo.

Prof. Susilo is a professor at the Royal Institute of Technology (KTH) in Sweden, and is active in the International Association for Travel Behaviour Research (IATBR). In this mini-seminar, he explained about the open-source application “MEILI,” which was developed by him and his colleagues. “MEILI” is an application that collects GPS traces of multiple users from the origin to the destination of their trips. It has been increasingly adopted in urban traffic surveys in developing countries by European countries and JICA. Moreover, some application examples of “MEILI” have been introduced. 

[22 February, 2019]

We invited Dr. Jin Murakami from City University of Hong Kong to hold the following seminar.

Date: July 18, 2016 (Monday) 16:30-18:00 @ Conference Room 1, 1F, Midorigaoka Bldg. 6

“Public Land around Transportation for Sustainable Finance and Urbanism: Hong Kong, Singapore, and Mainland China”
By Jin Murakami, Ph.D.
Department of Architecture and Civil Engineering, City University of Hong Kong

[Abstract] While transportation infrastructure has been seen as a “backbone” in Asian city-states’ territorial development strategies, public land administration has been playing an even more pivotal role in achieving their sustainable finance and urbanism under state leasehold systems. Despite its practical importance, there is still a paucity of empirical research on public land transactions around transportation facilities across Asian city-states. This research presents how selected Asian city-states successfully or unsuccessfully coordinate public land leases together with mega-transportation infrastructure projects from both financial and geographical perspectives. This presentation also covers some figures and preliminary analysis on private (non-residential) property transactions and real estate investment trusts (H-REITs) in guiding the World’s densest urbanization of Hong Kong and stresses the importance of strategic public-private land coordination in shaping Japan’s “compact cities” in competitive and sustainable ways.

The Transport Studies Unit (TSU) of Tokyo Tech will hold the following seminar on route choice modeling as part of the activities of the Grant-in-Aid for Scientific Research (Kakenhi), “Systematization of Evaluation and Operation Methods for Travel Time Reliability in Urban Transportation Systems”, and the New Road Technology Development Project, “Research and Development of ‘Data-driven’ Transportation Demand and Spatial Management Using ETC2.0 Probe Information”. The seminar on route selection modeling will be held as part of the activities of the new road technology development project “Research and Development of “Data-driven” Traffic Demand and Spatial Management Using ETC2.0 Probe Information”.
