Socioeconomic disparities in heat exposure in India
Heat exposure is an escalating public health concern, where limited policy attention and infrastructure constraints hinder effective risk assessment and response. This study introduce a multi-perspective and multi-scale analytical framework to quantify socioeconomic disparities in heat exposure using spatiotemporally resolved data, providing key insights for targeted public health interventions and policy development. Taking India as the study ar…
Enhancing geospatial retail analysis by integrating synthetic human mobility simulations
The accuracy of retail location models depends on their precise calibration, but the data necessary for such a key task is seldom available. In this research, we use synthetic human mobility data, which introduces commuting dynamics, to improve the reliability of such models. We use the origin-destination flows to distribute households' potential expenditures in their home and commuting locations with the aim of modeling non-residential-driven de…
Evaluating the subjective perceptions of streetscapes using street-view images
Developing a model to evaluate urban streetscapes based on subjective perceptions is important for quantitative understanding. However, previous studies have only considered limited types of subjective perceptions, neglecting the relationships between them. Further, accurately measuring subjective perception with low computational costs for large-scale urban regions at high spatial resolutions has been difficult. We present a deep-learning-based …
A cost-and-effect simulation model for compact city approaches
Japan's compact-city policy addresses rapid population decline and aging to ensure sustainable development. However, its implementation requires significant time, financial resources, and complex stakeholder collaborations. Faced with these challenges, we asked: How can the cost-and-effect of planning be simply and automatically recognized by stakeholders? To address this, a simulation model was developed for evaluating urban planning strategies …
Emotions, behaviors and places
Emotions are the basis of human behavior and an important part of spatial constructions. Despite numerous efforts to leverage spatio-temporal big data from social media to capture public sentiments, there is a lack of understanding of how individuals' behaviors play a role in people's sentiments at places they visit. Thus, this study aims to advance our understanding of the complex relationships between sentiments, behaviors, and places. Through …
Social segregation levels vary depending on activity space types
Given the dynamic spatial characteristics of modern cities, the issue of social segregation based on activity spaces has been gaining increased attention. However, few studies have performed a detailed comparison of the differences in social segregation at different types of activities space on the citywide scale with a relatively small granularity from both place and individual perspectives. To gain a better understanding of the intricate and dy…
Road-reconstruction after multi-locational flooding in multi-agent deep RL with the consideration of human mobility - Case study
Record-breaking heavy rain occurred in Western Japan from June 28 to July 8, 2018. Many roads in Hiroshima and Okayama Prefecture were disrupted simultaneously. The government desired the rapid recovery of disrupted human mobility; however, the restoration of roads that were frequently used by citizens was delayed for a week after this flooding. There are three challenges to overcome for an efficient disaster road management plan: 1) the lack of …
Development of current estimated household data and agent-based simulation of the future population distribution of households in Japan
In response to the declining population and aging infrastructure in Japan, local governments are implementing compact city policies in the form of location normalization plans. To optimize the reorganization of urban public infrastructure, it is important to provide detailed and accurate forecasts of the distribution of urban populations and households. However, several local governments do not have the necessary data and forecasting capability. …

Estimation of earthquake damage to urban environments using sparse modeling
For the establishment of precise disaster prevention measures in response to the Nankai megathrust earthquakes predicted to occur in the future, it is necessary to conduct numerous earthquake simulations and evaluate the vulnerability of the urban environment quantitatively. This vulnerability is evaluated on the basis of factors such as the extent of damage from earthquakes, as well as the attributes of residents, urban infrastructure, and syste…
Analyzing Road Coverage of Public Vehicles According to Number and Time Period for Installation of Road Inspection Systems
Shortages of engineers and financial resources have made it difficult for municipalities to identify and address problems with aging road infrastructures. To resolve these problems, numerous studies have focused on automating road inspection, including a study in which we developed a smartphone-based road inspection system. For efficient operation of the system, it is necessary to understand the usage of vehicles in which the system will be insta…
