With the technological developments, railway transportation has become an important part of urban transport. Besides increasing the accessibility in the city, the railway creates demographic, economic, and spatial effects. In planning, railways are used to increase or direct urban development. This study evaluates the railway investment as an exogenous effect on the city. Furthermore, this study examines the railway’s as a complementary factor of the urban development trends. Urban development is analyzed with two main factors; population and employment. When the urban development in the city of Izmir between the years 2009 and 2019 is examined, it is observed that population and employment were decentralized from the metropolitan region to the north and south subregions which IZBAN serves; in addition, while sectors such as industry and agriculture are decentralized in sectoral employment in the metropolitan area, it is observed that the service sector is concentrated. Neighborhoods within the Izban impact area (IZBAN neighborhoods) and outside the IZBAN impact area (non-IZBAN neighborhoods) were compared based on population and employment changes. At the same time, the increase in employment in the metropolitan area wasconcentrated around the station, both population and employment change in the north and south sub-regions. There is a significant difference between IZBAN non-IZBAN neighborhoods. As the distance to the station decreased in the north and south subregions, employment increased, and employment intensified around the station. It has accelerated the suburbanization around the north and south sub-regions.

Transformative Urban Railway: Ankara Commuter Line and Lost Landscape
Baş Bütüner, Funda; Aral, Hacer Ela (2017-09-27)
Being major transportation infrastructure of the 19th and early 20th centuries, the impacts of railways on cities have highly directed urban studies,. deforming material edge of cities, encouraging urban extension, forming new territories, and speeding up urban development. However, in recent decades, with newly emerging landscape infrastructure practice, a new idea for a more integrated infrastructure and landscape system has started to be formulated. Railway strips, occurring as territories where solid-vo...
Evaluating the Relation Between Station Area Design Parameters and Transit Usage for Urban Rail Systems in Ankara, Turkey
Ozgur-Cevher, Ozge; Altintasi, Oruc; Tüydeş Yaman, Hediye (Springer Science and Business Media LLC, 2020-08-01)
Urban rail transit (URT) systems are particularly favoured by planners due to their potential in attracting car users. However, a URT investment must be complemented by land-use characteristics at macroscale (whole city) and design parameters at microscale (vicinity of the station). Despite the common referencing to key concepts (i.e. density, diversity and connectivity), the variability in their definitions and scales causes ambiguity in the determination of their quantified impact on URT ridership. Furthe...
Assessment and simulation of car access control policies in city center: the case of Tunalı Hilmi Street in Ankara
Doğan, Murat; Babalık, Ela; Tüydeş Yaman, Hediye; Department of City and Regional Planning (2014)
Since the Second World War, private car use has been increasing in the world, affecting particularly urban areas and their city centers, which suffer from severe levels of congestion, pollution and traffic safety problems. In order to solve traffic problems in city centers, there needs to be a policy for car access control, which can be achieved through Travel Demand Management and Traffic Management. This study, analyses possible effects of transforming the Tunalı Hilmi Street in Ankara into a pedestrian a...
Evaluation of rail freight transportation in Turkey prior to deregulation
Cebeci, Alper; Tüydeş Yaman, Hediye; Department of Civil Engineering (2019-3-16)
Rail freight is a major component of industrial development in a country, as it provides very cheap transportation opportunities for raw materials, such as coal, ores, etc. However, due to its stop-to-stop nature, it always requires a first- and last-mile connection with another mode, thus, has relatively longer total travel times. As a results, it can hardly earn the revenues necessary for its operations and has been heavily subsized by govermnets in many coun...
Evaluating Rail Passengers Sector in Turkey
Ekici, Üsame; Tüydeş Yaman, Hediye; Department of Civil Engineering (2022-1)
With the rapid development of railways in Turkey, the research of railway passenger demand forecasting has gained much importance in the recent years. Passenger demand forecasting for transport services is essential for better management and better resource planning. In this study, a time-series-model was established using Auto Regressive Integrated Moving Average (ARIMA) forecasting method and then a regression model was formed to forecast the intercity railway passenger flow in Turkey. The daily passenger...
