While studying the level of pedestrian activity on the campus of Middle East Technical University (METU), Ankara, pedestrian flow maps, counted manually and multiple times a day, showed changes in directionality and volumes of pedestrians during a day. Also, a student survey revealed that, in overall, 60% of the participants found the METU campus walkways sufficient, while the remaining 40% found it insufficient. Students stated that existence of sidewalks on both sides, infrastructure, protection against to weather, and etc. had an important effect on increase in walking. To encourage a greater modal shift to walking on the campus, first, it is important to understand and evaluate walkability and walking concepts. While walkability assessment studies mainly deal with perception and built environment aspects, engineering studies focused on evaluating pedestrian level of service (PLOS) based on flow and infrastructure capacity measures. This perspective difference and methodological details resulted in requirement of a wide range of data, which vary greatly based on the scope of the study. PLOS evaluations for METU Campus walkways are performed using Highway Capacity Manual (HCM), Gainesville and Trip Quality methods, which resulted in contradicting ratings. Comparison of the results revealed insights about the strength and weaknesses of each method, and led to a series of recommendations to improve walkability assessments, which was the main goal of this study.

Production of the sidewalks : the case of Atatürk Boulevard Gülkök, Işıl; Keskinok, Hüseyin Çağatay; Department of Urban Policy Planning and Local Governments (2013) This thesis is a study on the spatial and also ideological processes regarding Ankara- Ataturk Boulevard sidewalks. The main concern of this study is to discuss the pattern of determinants in the process that led to appreciation of public life, de-appreciation of public life/ appreciation of the pedestrian and finally de- appreciation of the pedestrian; and respectively production, re-production and de-construction of sidewalks, in the frame of Ataturk Boulevard case. It would be unfairness to consider the ...
Gated communities as a new upper-middle class "utopia" in Turkey : the case of Angora Houses Ertuna, Ayberk Can; Şengül, Hüseyin Tarık; Department of Urban Policy Planning and Local Governments (2003) The aim of this thesis is to analyse the effects of gated communities in the increasing fragmentation of urban space and in the increasing polarisation among different classes in the Turkish context, more specifically in the capital, Ankara. Since the case study is based on an upper-middle class suburban gated community, first, suburbanisation أas a wave of urbanisationؤ is analysed. Then, the debates about the middle class and the transformation that this social stratum has undergone are discussed. Later, ...
Re-reading the social context of apartment block development in İstanbul: 1889-1922 Aktuna, Zeynep; Güvenç, Murat; Department of City and Regional Planning (2003) The thesis investigates the early phases of apartment block development in Istanbul, which took place in the second half of the 19th century. Apartment block development represents a unique process in Istanbul. It not only reflects the أwest-orientedؤ side of the Ottoman Empire but also sheds light on the transformation of urban fabric from pre-modern to modern. The emergence of apartment blocks in Istanbul, hence, does not simply imply the adoption of a أwesternؤ and أmodernؤ life, but also reflect a spati...
Spatial transformations of the waterfront-as an urban frontier case study : Durres a port city Koçi, Valbona; Sargın, Güven Arif; Urban Design in City and Regional Planning Department (2005) This thesis explores the spatial transformations of the waterfront اan urban frontier - of Durrës port city in Albania, within a predefined timeframe: before, during and after socialism. Within this framework, a special concern of the thesis is the examination of the impact of political, social and economic actors, as well as the morphological and geographic conditions, which occur when transforming the urban space and environment. Thus, the work is constructed on the basis of cause (urban process) ا effect...
Pedestrian experiences in Bahçelievler 7th Street: setting the design criteria for the enhancement of urban public realm Akit, Mert; Bilsel, Fatma Cânâ; Department of City and Regional Planning (2004) This thesis aims to set out an urban design framework, based on pedestrian experiences and pedestrian spaces, in order to take up streets to design or enhance them as pedestrian friendly urban public places. This could also be considered as a model of approach, which assumes a normative manner. Pedestrian urban places are surveyed, then analyses are drawn that will lead to design. In that framework, the study first summarizes theoretical concepts of urbanity, urban quality and pedestrian experiences, which ...
