Invited talks by Prof. Iwan and Prof. Wido from Diponegoro University

We had invited talks by the guests from Diponegoro University, Iwan sensei, and Wido sensei. It was a nice opportunity to understand the state-of-the-art researches in Indonesia in the field of urban and regional planning.

We also have an informal “second” final master defense for the linkage students. Well done!

Congratulations!

Four master students have just completed their study in our lab. Many congratulations on your graduation, Ei Ei, Alex, Hulio, and Hendra san!

PS. We are lucky enough to have two guests, Iwan sensei and Wido sensei, from Diponegoro University on such a memorial day.

Seminar on Recursive Logit Model

A recursive logit model and its extensions can be utilised for a wide range of issues in the urban and transportation field, such as modelling activity-travel behavior in a time-space prism, and modelling route choice behavior on a large-scale road network. In this study camp, we first review existing studies in details and the prepare programming codes to execute recursive logit model and its extended versions.

Seminar on Machine Learning

For about a quarter of a century, machine learning methods have been widely applied to traffic problems, including rule-based and activity-based model building.
For about a quarter of a century, research has been widely conducted on the application of machine learning methods to traffic problems, including the construction of rule-based activity-based models. In recent years, there have been a number of studies that extend machine learning methods in a way that is consistent with traffic theory.
Recently, there have been a number of studies that extend machine learning methods in a way that is consistent with traffic theory. Such machine learning methods that are consistent with traffic theory
with traffic theory are superior not only in terms of theoretical validity, but also in terms of improving prediction accuracy.There have been several reports on machine learning methods that are consistent with traffic theory. In this workshop, we will discuss the academic and technical aspects of the transportation field, where the use of big data and passive data is becoming more and more widespread.

The study group will review the application and extension of machine learning methods in the field of transportation, taking into account the academic and practical situation in the field of transportation, where the use of big data and passive data is becoming more and more widespread.
The aim of this workshop is to organise the application and extension of machine learning methods in the field of transportation, where the use of big data and passive data is becoming more and more widespread.

Congratulations Ei Ei and Hendra!

Two lab members just finished their master thesis on August,8th.

Melanton Hendra Siregar
“The Impact of Railway Stations Development on Land Price: A Case in West Japan”

 

Ei Ei Tun
“Emergency Shelter Location – Allocation with Time – Varying Demand: A Case in Higashi – Hiroshima”

 

They did incredible work hitting this award! I’m very happy that both of them got the Excellent Master Thesis Awards (Hendra san got the First Place of Excellence, and Ei Ei san got the Second Place of Excellence). Congratulations and best wishes for your continued success in the future. I wish nothing but the best for you.
