Wei Wu, Prasanna Divigalpitiya, Assessment of Accessibility and Activity Intensity to Identify Future Development Priority TODs in Hefei City, Land, 10.3390/land11091590, 11, 9, 2022.09, Hefei, the capital city of Anhui Province, China, has been experiencing rapid development due to fast population growth and continuous city expansion since 2010. The Hefei government began to operate the subway system in 2017 and introduced the concept of transit-oriented development (TOD) as a strategy to reduce traffic pressure and environmental pollution. By 2020, there were 77 TODs in operation. However, some TODs could not attract enough public transport passengers or increase the economic activities. This study analyzed the Hefei City TOD network and tried to identify TODs that need development priority among the existing TODs to guide the efficient allocation of resources for the development of the TOD network. First, this study measured the accessibility and activity intensity at each TOD by using the node-place model. Second, the 77 existing TODs were divided into 4 priority levels by applying the silhouette method. Level 1 and level 2 TODs have development priority and are referred to as "Unstable TODs" and "Unbalanced TODs," respectively. Finally, this paper provides some strategies for developing these priority TODs..

16.	Carlos E.R. Gonzalez, Prasanna Divigalpitiya, Takeru Sakai, The potential of participatory design to improve urban spaces in the slums of Caracas, Venezuela, WIT Transactions on Ecology and the Environment, 10.2495/SDP170411, 226, 1, 469-478, 2017.06, © 2017 WIT Press. It may be said that slums have become one with Caracas, and so to eradicate them completely would be almost impossible task. A more suitable solution therefore is to rehabilitate these areas, and improve the current living environment. Taking into account the meagre access to construction materials, the prevailing social conditions, and the absence of appropriate planning, we studied the potential of involving the inhabitants themselves through Participatory Development. After a detailed analysis of the current urban spaces, and following consultation of the local community, as well as professionals working in this field, we are able to generate lists of priorities based directly on the local inhabitants’ needs and desires, including: playgrounds; pathways; green areas; community centres; and other forms of small to medium-scale projects. This forms the basis for developing proposals to improve their community with their involvement and assistance. As was the case with urban projects such as ‘Espacios de Paz’ and ‘Inclusión de Habitantes’ (which included aspects of Slum Upgrading strategies and Participatory Design in slums of Venezuela), we conclude that shifting the methodology from slum eviction to slum upgrading fosters inclusion and respect for local heritage and culture, and creates a more sustainable and human-focused approach that aims to provide solutions to an on-going, deep-seated challenge..

Taher Osman, Prasanna Divigalpitiya, Takafumi Arima, Driving factors of urban sprawl in Giza Governorate of Greater Cairo Metropolitan Region using AHP method, LAND USE POLICY, 10.1016/j.landusepol.2016.07.013, 58, 21-31, 2016.12, Based on questionnaire surveys and the AHP method, this paper determines the driving forces of urban sprawl and analyzes their relative influence on sprawl in the middle, north, and south sectors of Giza Governorate, which is located in the western part of the Greater Cairo Metropolitan Region. Sprawl patterns in the study area were influenced by seven driving forces: geographical characteristics, availability of life facilities, economic incentives, land demand and supply, population increases, administrative functions, and development plans. These forces have varying degrees of influence in each sector. Amongst these forces, economic incentives in the middle sector, population increases in the north sector, and administrative functions in the south sector were the forces most influential in urban sprawl.

In this respect, the authors examined the effect of urban characteristics of unplanned settlements on SD in the Egyptian context, focusing on the type of unplanned growth on agricultural land. The output of the analysis were fourfold. First of all, we provide a brief overview of previous research on the main types of unplanned settlements in GCMR and the sustainability definition according to the Egyptian context. Secondly, we had a discussion with the local government during our field survey in GCMR to determine the study samples, the main urban characteristics, and the sustainability evaluation criteria in the Egyptian context. Thirdly, through the comparative analysis and geographic information system (GIS), we examined how the character of urban development affected per capita four urban measures in a cross-section of two settlements, one represented the unplanned settlements and other as a comparative planned sample to determine the real gap. Finally, by using the evaluation matrix, the help and block items are estimated for each measure of urban characteristics, providing substantive evidence on how the four measures of urban characteristics have been affected by the urban sprawl..

Taher Osman, Prasanna Divigalpitiya, Takafumi Arima, Quantifying the Driving Forces of Informal Urbanization in the Western Part of the Greater Cairo Metropolitan Region, ENVIRONMENTS, 10.3390/environments3020013, 3, 2, 1-17, 2016.06, This paper discusses the driving forces (DFs) of informal urbanization (IU) in the greater Cairo metropolitan region (GCMR) using the Analytic Hierarchy Process (AHP). The IU patterns in the GCMR have been extremely influenced by seven DFs: geographical characteristics, availability of life facilities, economic incentives, land demand and supply, population increase, administrative function, and development plans. This research found that these forces vary significantly in how they influence urban growth in the three study sectors, namely, the middle, north, and south areas in the western part of the GCMR. The forces with the highest influence were economic incentives in the middle sector, population increase in the north sector, and the administrative function in the south sector. Due to the lower availability of buildable land in the middle sector, the land demand and supply force had a lesser influence in this sector compared to in the north and south sectors. The development plans force had medium influence in all sectors. The geographical characteristics force had little influence in both the middle and the north sectors, but higher influence than economic incentives, availability of life facilities, and development plans in the south sector. Because of the spatial variances in life facilities organizations in the GCMR, the life facilities availability force had little effect on IU in the south sector..
20.	Taher Osman, Prasanna Divigalpitiya, Mustafa M. Osman, The impact of Built Environment Characteristics on Metropolitans Energy Consumption: An Example of Greater Cairo Metropolitan Region, BUILDINGS, 10.3390/buildings6020012, 6, 2, 2016.06, This paper examined the influences of the built environment and socio-economic driving factors on domestic gasoline consumption in developing metropolitan regions through a case study of the greater Cairo metropolitan region (GCMR), Egypt. Structural equation modeling (SEM) was used in analyzing the causality of the domestic gasoline consumption. The influences of major factors hypothetically affecting the domestic energy consumption such as resident characteristics and built environment characteristics were examined. The results proved a high positive influence of the resident's income and the number of adults as driving factors, directly and indirectly, affecting energy consumption levels. Population density and attitude towards eco-friendly driving factors proved to be a very low influence on energy consumption. The built environment driving factors such as access time to public transportation and related building characteristics factors proved to have a low impact on energy consumption. The study findings suggest that the design of a built environment should be well related to the socioeconomic factors to manage the domestic energy consumption in developing regions..

So as to estimating these indicators, various data sources are selected, including land use maps, digitized map of the highways and town centers, and population statistical data, etc. GIS spatial analysis methods are used to spatialize these indicators into 120 m x 120 m cells. In addition, an incorporated sprawl index (ISI) is estimated by weight sum of these indicators. The results demonstrated that geo-spatial indicators system can captivate most of the exemplary attributes and interior differentia of urban sprawl. Building land in Cairo has kept quick growing with considerable amount of low efficacy and dysfunctional spatial disposition. The subsequent sprawl attributes are determined by each indicator's exemplary spatial disposition of urban sprawling, conspicuous fragmentation and unevenness of landscape due to ineffective implementation of land use planning, improper pattern of exemplary discontinuous development, strip development and leapfrog development, low efficacy of sprawl, low development density, low population density output in newly developed areas; and unfavorable influences on agriculture and environment and population life..

This research discusses housing policies changes and their effects on the housing issue in GCMR. Primary data were derived through questionnaire survey and secondary data from national censuses. The results find that the change in the general state policies did success in attracting more investments for public housing of low-income residents but failed to end the phenomenon of vacant housing or attract slums residents to new urban centers (NUC)..

Most of the historic map data available for the CMR before 1990 are temporally sporadic and spatially incomplete. As an alternative to maps, classified remote sensing data are used to analyze the urbanization process. Logistic regression is applied to derive factors of urbanization and the various relationships among them. The relation between 'urban' and 'non-urban' serves as an explanatory variable. The factors explaining that relationship are calculated by exploratory logistic regression analyses. The probability calculated from the statistical model is used for CA transition with a random number. Several growth patterns are simulated based on a range of transition thresholds to test the CA model. Status quo growth and several growth control scenarios are simulated for the period from 1987 to 2002 based on an optimum threshold. The simulation result of the status quo growth is evaluated with several evaluation methods. The level of agreement between the estimated result from the status quo model and the actual data is 62%, while the multi-scale goodness-of-fit method produces highly accurate values for the given range of resolutions..
33.	Development of a Land Use Planning Support Tool in the Developing Countries The purpose of this paper is to develop a land use planning support tool (LU-PST) in developing countries. LU-PST consists of an urban growth model and a land use zoning map support tool. The urban growth model is a Cellular Automata (CA) model, and population density by grid cell is calculated. The purpose of the land use zoning map support tool is to create zoning maps including residential, commercial, industrial and preservation zones. This tool used an AHP method in order to consider criterion for judgment of users. In order to develop the LU-PST, these two models were incorporated into ArcGIS (ESRI). It is possible for this tool to execute two tasks. One is for the land use zoning considered with urban growth trend. And the other is for the urban growth calculation based on a land use plan. The usefulness of LU-PST was discussed by analyzing the results of application to the Colombo Urban Area in Sri Lanka and considering comments about this tool from urban planners..

International Activities
My international activities are mainly related to the educational activities as an associate professor in Kyushu University and as a member of various committees in academic societies and international students exchange programs. I joined the newly formed International Masters and Doctoral course of Graduate School of Human Environment Studies of Kyushu University as an Associate Professor in March 2010. My main duties in this program is promoting the program in Asian Universities and managing the program in addition to the educational activities. During this period I have manage to organize series of lectures by invited scholars from overseas universities. Those lecture series has built the foundation for much needed international relationships for the program.
The department of Architecture and Planning in Kyushu University is a partner of student exchange program with 12 partner universities from Europe, Pacific, Korea and Japan. I continuously worked in the organizing committee of this program representing Kyushu University. I have utilized those opportunities to introduce Kyushu University and its research opportunities to overseas universities. Department of Architecture and Planning of the Kyushu University in their international program conduct number of urban design workshops with overseas universities both in Kyushu University Hakozaki campus and in foreign universities. These programs are organized and conducted by a team of professors where I was a member. From April 2017 Department of Architecture and Urban Planning started International graduate education program under the Campus Asia Project sponsored by Japan, China and Korea. At the moment I am a member of the international working committee planning future student exchanges and double degree program organized in that project.
Social Contribution
My social contribution is mostly based on activates organized by the academic societies and government agencies. The Asian Townscape Award is an annual award organized to recognize best practices of Asian townscape designs. This award is organized by Asia Townscape Design Society, Asian Habitat Association, and UN-HABITAT Fukuoka office. I have worked as a judge in the selection committee for awards. In recent years there are recommendations for the award from wide range of Asian countries including Japan, China, Korea South Asia and Southeast Asia. I functioned as a specialist in South and Southeast Asian cities in this selection committee..
