It is concerned in the local government it becoming severe to offer public service at the same level now by annual revenue decrease under a population decline and aging society. Emerging pressures for more efficient and effective public management require more rational approach in forecasting future demand for public services before such problems will be actualized. Our laboratory develops the method to estimate the future distribution of population or households and grasp the change of urban service demand including transportation using urban model considering interaction between land use and transportation, in particular, microsimulation model. And we evaluate policy measures for sustainable urban structure, such as encouraging relocation policy to , improving or rebuilding of public transport network.

To scientifically understand the risk of traffic accidents is essenntial for implemention of an effective and efficient traffic safety management.

This study aims to construct a road traffic safety management method that combines traffic big data such as vehicle probe data, drive recorder data, collision warning data, 3D road space data, and citizen near-miss incidents, in addition to traffic accident statistics. Specifically, in Toyohashi, Nagoya, and other cities in Aichi Prefecture, and Penang, Malaysia, we are conducting a detailed understanding of road traffic situation; developing a statistical model of accident risk; evaluating the risk of traffic accidents by location and accident type and analyzing the factors of those accidents; developing detailed traffic flow models at specific accident risk locations; and planning and evaluating traffic safety measures based on those models.

In recent years, the way Japanese children move has been attracting an attention around the world. In Japan, most elementary schools allow children to walk to and from school on their own, and even outside of school, children are encouraged to move independently from a young age. It has been suggested that this may also contribute to the promotion of health. On the other hand, in other countries, car-dependence may lead to the problem of child obesity, and parental transportation causes traffic congestion during peak hours, as the children are mainly transported to and from school by parents and school buses.

In this study, we investigate children's mobility in Japan, Malaysia, Indonesia, Australia and other countries, and examine how to improve children's mobility through comparative analysis focusing on Children Independent Mobility (CIM), traffic safety and crime prevention.

In addition to the themes above, we are conducting researches on the evaluation of road network plan and traffic management plan using simulations, and research on regional public transportation management.
