The lab studies next-generation infrastructure and cities through the lens of human behavior and economics.

AboutAbout the lab
Uncovering the interactions among people, information, and infrastructure
The Next-Generation Infrastructure Systems Lab studies human behavior related to infrastructure, as well as the effects that infrastructure development has on society and the economy.
The lab represents people's spatiotemporal behavior with mathematical models and quantitatively evaluates the effects of policies using econometrics and cost-benefit analysis.
Its work includes predicting people's behavior in a smart society, designing policies that support the development of urban and regional economies, and extending those ideas to other countries.
Weekly student-led lab seminars are at the center of its activities, along with joint lab seminars with international project groups and joint lab seminar retreats with other universities.
Key terms
- Cost-benefit analysis
- A method of evaluating a project by converting its costs and the benefits society gains from it into monetary terms and comparing them
- Value of time
- A value expressing how much money people consider a reduction in travel time to be worth
- Discrete choice model
- A mathematical model that expresses, as probabilities, which option a person will choose from a set of alternatives

ResearchResearch themes
The lab takes a comprehensive approach, combining mathematical, economic, and behavioral science methods, to study the advancement of infrastructure systems and the socioeconomic effects of their development. Covering a wide range of spatial systems, from the national level down to the individual level, it aims to produce academic findings that are useful for planning and policy decisions.
*Illustrative imageMeasuring the benefits of transport projects
The lab studies the benefits of travel time savings, which account for a large share of the economic evaluation of transport projects, and the value of time on which they are based. It is also exploring ways to incorporate the benefits of improved travel time reliability into project evaluation.
*Illustrative imageAnalyzing nationwide traffic flows
The lab analyzes wide-area traffic flows connecting regions across the whole country. Its past work includes the effect of electronic toll collection (ETC) on expressway traffic demand, and behavioral models based on national surveys of household car ownership and use.
*Illustrative imageUrban traffic and pedestrian behavior
Focusing mainly on the Tokyo metropolitan area, the lab analyzes traffic flows within cities. For crowded spaces such as inside train stations, it has long been building pedestrian behavior models and simulators using image processing and discrete choice models.
