Recently, the importance of Transit-Oriented Development(TOD) of cities based around railway stations is being emphasized. This study aims to evaluate and classify 152 railway station areas from the viewpoint of Transit-Oriented Development by analyzing the target areas located in a 30km circumference surrounding Central Tokyo. By using the Principal Component Analysis, 4 factors were consequently drawn to evaluate the railway station areas: 1)Integration of urban function, 2)Connection and serviceability of public transit, 3) Change-rate of urban function, 4)Urban self-reliance. As a result of typology, it is possible to classify seven types of railway station areas. Each type's characteristics and problems are clarified through the analysis.

One of the most traditional and growing major cities in Saudi Arabia, Jeddah City established building design standards for villas and apartments in 1960. These design standards have changed several times in response to population increases. However, these standards have had adverse effects on streets: 1) motorization has created pressure on planned neighborhood streets, which resulted in an unsafe environment for pedestrians who must share the road with vehicles. 2) Because of the lack of availability apartments in mixed land-use neighborhoods, the municipality has allowed apartments to be built in desirable villa neighborhoods. Apartment and villa neighborhoods had been separated until 2007 because of privacy concerns. The new combination of buildings has resulted in a loss of privacy in villas overlooked by apartment buildings. Apartment residents are also parking their cars in villas' front yards because of a parking shortage. This study aims to 1) make spatial configuration arrangements of design standards, 2) define the spatial configuration combinations of streets and residential buildings by analyses of the expanding urbanization process, and 3) identify the issues with streets and determine a method to avoid such issues in future neighborhood planning. This study found: 1) a reality gap in design standards, such as the setback line and its relation to parking spaces, 2) unsuitable assumptions regarding car ownership per household, which resulted in a parking shortage, and 3) that resident use of sidewalk spaces as a semiprivate space negatively impacts the pedestrian environment.

During the urbanization process in Jeddah, evidenced by an annual population growth rate of 9.5%, vacant lots have existed in developed residential areas in spite of the housing shortage. This study aimed at investigating the housing shortage problem and suggesting future solutions based on a predictive formula through four tasks: (1) examining the issues induced by population growth; (2) assessing the extent to which articles in the Procedure Manual for Preparation of Residential Land Subdivision (PMPRLS) foster diversity within villa-type neighborhoods; (3) clarifying the extent of the applicability of these articles and the contribution of existing neighborhood patterns to the housing shortage problem; and (4) providing recommendations for developing each kind of villa-type neighborhood to contribute to resolving the housing shortage. The proposed development methods for villa-type neighborhoods were derived from a correlation analysis using PMPRLS-related indicators in all such neighborhoods (103 study sites) in Jeddah and from a predictive regression analysis. This study suggests that each neighborhood class can contribute to resolving the housing shortage problem. In conclusion, diversifying lot areas, population density, and lot widths in current villa-type neighborhoods would have a positive impact on the housing shortage problem.
