Planning and management of spatial economic systems, and mathematical analysis and control of urban traffic evolution

This group consists of Akamatsu laboratory and Satsukawa laboratory.
 
Akamatsu Labo studies mathematical and computational methodologies for planning/managing urban/transportation systems in the following three fields.
1)Transportation Science & Transportation Planning: We develop novel transportation demand management schemes to solve road congestion problems by exploiting recent advances in information technologies and computational mechanism design theory.

2)Regional Science & Spatial Economics: Most of the world's population is strikingly concentrated in a limited number of areas. We study mathematical models to explain the economic mechanisms of such agglomeration patterns in geographical space.

3)Investment Science & Mathematical Finance: Urban infrastructures are exposed to various risks due to changes in economic environment. We develop control-theoretic methods to achieve better decisions for investment / management of infrastructure systems under uncertainty.
 

Satsukawa Lab studies
1) Evolutionary analysis and dynamic control of urban traffic: Analysis of spatiotemporal traffic flow patterns self-organized by adaptive travel behavior and their evolution, development of dynamic traffic control schemes via evolutionary game theory and optimization, and theoretical guarantees of convergence and stability.

2) Mechanism design for urban transportation: Mathematical methodologies for the institutional and pricing design required to implement new mobility services such as automated vehicles, mobility sharing, and MaaS, via game theory and optimization.
