Bangkok is a city where the congestion levels have been a major problem for many years. In 2017, Bangkok was rated the most congested city in Asia, and the second most congested in the world. According to The Expressway Authority of Thailand (EXAT), on-ramp merging is one of the most critical problem that causes congestion on the urban expressways. EXAT have evaluated several merging control strategies through microscopic traffic simulation to find suitable strategies for implementation in real life. However, their simulation studies were all based on the assumption that all motorists strictly follow the traffic rules. This is not the actual case in Bangkok, where the drivers ignore both solid lines and striped areas, as well as utilize the shoulder lane on a regular basis. The aim of this thesis is to investigate if it is possible to include this complex driving behavior in existing microscopic simulation models. A second objective is to identify merging control strategies that can reduce the occurrence and the effects of this driving behavior in order to increase the throughput at an on-ramp area on Sirat Expressway. A model was built in VISSIM and calibrated based on data collected from video recordings. In the study, parameters that are significant for the driving behavior modeling, as well as the difficulties that arise from performing a realistic calibration of the model using video observations and model-specific constraints, are identified. From the video recordings it was discovered that the main problem causing the congestion was a result of the mainline traffic who traversed to the on-ramp. Two merging control strategies were suggested to address this problem: the installment of a center barrier, and successive merging areas. The results confirmed that both actions can improve the traffic situation in terms of reducing the individual travel time. Installing a center barrier was the most efficient option and reduced the travel time by 16.58 % on the mainline and 63.24 % at the on-ramp.

Global urbanization led to a rather new phenomenon: urban refugees, who live on the margins of big cities. This study highlights the particular struggles and difficulties urban refugees from different contexts and backgrounds have to cope with in Thailand. The aim of this thesis is to better understand their living situation in Bangkok, contributing to the limited literature in this field. As Thailand does not recognize refugees legally, they try to make a living under tough conditions, fearing arbitrary arrests. Furthermore, these conditions lead urban refugees in Bangkok to live in their own communities, often separated from the Thai society. Being under these constrained living conditions, having limited access to health care, education and work, harms their well-being. The theoretical underpinnings provide the necessary framework to discuss the findings, focusing on the interplay between structure and agency, the exception of being a refugee in transit and waiting for resettlement, incorporating approaches like (im-)mobility, networks and dissimilation. The inductive design with a holistic approach, using semi-structured interviews and observations, offers profound knowledge from urban refugees themselves. The results display various aspects of refugees’ lives in Bangkok, like different reasons for moving to Thailand, lack of coherent and sustainable support systems, scarce experiences with the Thai society, vague legal status and its implications, their daily life or insights about their perceptions of the past, present and future. They are and will probably be one of the most vulnerable people residing in Thailand, trying to survive, lacking numerous basic and human rights.

Rapid transit systems often create city developments and raise the property values. Basically, residential property price is characterised by number of characteristics including the transportations attributes. Empirical studies have drawn impacts of transportation in different ways. This thesis studies the hedonic price model to better understand the influence of mass rapid transit systems on the prices of condominium in Bangkok. The research question is "How the accessibility of rapid transit system affects the price of condominium in Bangkok?" The thesis explains the relationship between condominium prices and accessibility to mass rapid transit systems, as well as other influences, using hedonic price model. The research conducts cross-sectional study approach that uses the data with high level of flexibility at a particular point in time. Five models have been used in this thesis including the entire area model, models of proximity to rapid transit station, and sub-area models. Consequently evidences from the entire area model indicate that proximity to the rapid transit systems has a significant negative effect on condominium prices. Besides, the research also points out number of important characteristics that influence the prices of condominium including distance to main street and public facilities in the area. However, the clustered models show that there is no significant effect of proximity to mass rapid transits on condominium prices. The thesis has raised the knowledge and gained better understanding of the hedonic price model especially its application to the property market. The findings of this thesis can lead to an analysis of property values as well as other price model in other field of study.

The purposes of the study are to (1) compare the opinions of faculty members and students concerning the present operation of student personnel services at Prasarnmitr, Srinakharinwirot University, and (2) to propose organizational principles appropriate for student personnel services. A survey instrument developed with the consultation of five professors who are experts in this particular area (See Appendix A) was used to collect the data. The data consist of responses from questionnaires that were administered at Prasarnmitr, Srinakharinwirot University to two hundred and sixteen undergraduate students and fifty-three faculty members. Responses from both faculty members and students were 77.97 per cent. In order to accomplish the purposes of the study, four research questions were formed. Descriptive statistical analysis and the t test were selected for use as the appropriate statistical techniques. Analysis of the data reveals that (a) both students and faculty members are quite knowledge about student services currently provided by the university, (b) faculty members and students' perceptions are the same as regards the present operation of student personnel services program at Prasarnmitr, Srinakharinwirot University, (c) faculty members and students' perceptions are the same with regard to proposed goals, planning and organizing, budgeting, facilities and equipment, and evaluation, and (d) responding faculty members agreed more strongly than did students on the proposed qualifications and functions of the Vice-President of Student Affairs and the choice of the staff of student personnel services.

The purpose of this study was to analyze the participation of females in the labor force in Thailand between 1960 and 1970. The demographic variables tested were age, sex, migration rates, employment, youth dependency ratio, and educational attainment. The findings of the study indicate that demographic trends are affecting economy, culture, and roles of women. Female participation rates in the economic sector increased, particularly in Bangkok. Although many Thai women still occupy traditional female roles, there are indications that sex roles are being modified as related to industrialization and urbanization.

The objectives of this dissertation are to: 1) identify the aspects of shopping environments that are important to people; and 2) identify strategies to maintain the cultural relevance and viability of traditional marketplaces in the new global economy. This dissertation uses a Content Identifying Methodology (CIM) to determine preferences of general Thai shoppers for different shopping environments in Bangkok, Thailand. The procedures include preference rating, scene description, and respondents' background surveys. Data were analyzed using factor analysis, content analysis, Analysis of Variance (ANOVA), canonical correlation analysis, and Multivariate Analysis of Variance (MANOVA). In addition, interviews with designers and developers of shopping environments are used to establish implications for future development, design, and renovation of shopping environments. Three major factors, environmental, shopping, and background, were found to influence preferences for shopping environments. The environmental factors include the perceived environmental types; spacious and well-organized spatial configurations; physical content, such as fresh products, vegetation, and sitting areas; and environmental conditions, such as maintenance level, crowdedness, and cool temperatures. Shopping factors include recreational and value shopping. Respondent's background factors include shopping behaviors and socio-economic backgrounds, such as age and household economic status. Shoppers prefer certain shopping environments based on their shopping purpose: recreational versus value shopping. Recreational shopping appeals to young, single, and big group shoppers at modern malls, which provide the most opportunities for exploring, recreating, and socializing. Value shopping appeals to older, married, and large family shoppers at traditional markets that offer the high quality fresh products at low price. The dissertation's findings are consistent with previous studies and support theoretical explanations in the environmental perception and assessment field. Coherence, complexity, legibility, and mystery, and the concept of affordance influence preference; and are useful in making recommendations. The results indicate that, by identifying the preferences and perceptions of Thai shoppers, it is possible to preserve important aspects of the traditional Thai marketplace. This is achieved by incorporating aspects of traditional Thai markets into new shopping environments; and enhancing existing traditional markets to give them broader appeal and make them more viable in today's economy. / Ph.

The purpose of the study was to examine home conditions, housing satisfactions, and allergen avoidance practices of people with allergic rhinitis, focusing on female patients who lived in an urban area in a hot, humid climate. The Morris and Winter theory of housing adjustment provides a theoretical base for this study. Nine hypotheses were tested to investigate interrelationships among home conditions, housing satisfaction in terms of health issues, allergen avoidance practices, and age. A sample of 41 female allergy patients aged 20 to 77 years completed a screening questionnaire and an in-depth survey questionnaire. The researcher visited their dwellings to conduct home observations and to take photos.Dust mite allergens were reported as the most common allergy triggers. Presence of cockroaches, presence of furry pets outdoors, molds in bathrooms, and molds in kitchens were the most common problematic home conditions. Open shelves, bookcases, drapes, horizontal blinds, and foam rubber pillows were the most common allergy related items found in respondents' bedrooms. Concerning health issues, the majority of the respondents were satisfied with their homes. Allergen avoidance practices were not followed regularly, particularly, using allergen-proof pillowcases and sheets, washing bedding in hot water, wearing a particle mask when vacuuming, using an exhaust fan, an air cleaner, a dehumidifier, and cockroach traps. The respondents who received suggestions from doctors were more likely to follow allergen avoidance practices than those who did not receive suggestions.The result shows a significant negative relationship between problematic home conditions and housing satisfaction in terms of health issues. A significant negative relationship between age and allergen avoidance practices was found. Older sufferers were less likely to use allergen-proof products. They also lived in older homes that were more likely to have allergy related conditions. The most common obstacles that prevented respondents from improving their homes in order to avoid allergens were cost of products, emotional attachment to pets, not having time to improve homes, and procrastination. Based on these findings, design recommendations, home maintenance recommendations, and lifestyle practice recommendations were developed. / Ph. D.
