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. Furthermore, their impact may be different in developing countries, where more mesoscale (corridor-based) effects are expected in the early stages of the URT network. This study aimed to evaluate mathematically the impact of eight selected station design and public transit supply variables on ridership, based on data collected at 14 stations of two existing rail system corridors, both metro (M1) and light rail transit (A1) lines in Ankara, Turkey. Principal component analysis (PCA) indicated three major groups of parameters: (1) land use, (2) public transit supply and (3) connectivity around stations. In single-variable regression models, density and diversity were not found to be statistically significant factors despite the commonly accepted conceptual relation to ridership. A multiple regression model with bus frequency and density (R-2 = 0.902) explained the ridership in Ankara URT systems more significantly at its early development stage. There was a significant difference between developed factor relations for both M1 and A1 lines, suggesting that mesolevel impacts should be considered in the evaluation of URT systems.

Evaluation of regional railway investment with urban development dynamics: The case of IZBAN in Izmir
Kul, Fahrettin; Yetişkul Şenbil, Emine; Department of City and Regional Planning (2021-11-29)
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 w...
Bus Rapid Transit System in Istanbul: A Success Story or Flawed Planning Decision?
Babalık, Ela (Informa UK Limited, 2015-6-30)
There is a growing tendency in cities around the world to invest in Bus Rapid Transit (BRT) systems in an attempt to improve the capacity and quality of public transport services. The appeal of BRTs is based on their ability to combine the service level of rail transit systems with the flexibility of buses at relatively lower investment costs, and this was the motivation behind the opening of such a system in the Turkish city of Istanbul in 2007. This system has attracted mixed opinions as to its performanc...
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...
Urban rail operators in Turkey: Organisational reform in transit service provision and the impact on planning, operation and system performance
Babalık, Ela (2016-06-01)
Many cities around the world have seen efforts to restructure the provision of public transport. While transit authorities as public agencies continue to deliver transit services in some cities, many others have privatised these services, have opened up the market to private operators or have outsourced them to newly founded subsidiaries. The situation is no different in Turkey, where new legislation was enacted in the 1980s enabling local authorities to establish corporate companies under their own agency,...
Investigating public transit daily travel behavior using smart card data: a case study of Konya
AL KRDY, MAJED; Tüydeş Yaman, Hediye; Department of Civil Engineering (2022-9)
As urban diversity grows in cities, so does the heterogeneity of public transit (PT) travel behavior. To accommodate for usage heterogeneity, a deeper understanding of travel behavior beyond descriptive analysis is necessary, which can be performed using smart card data (SCD), if available. In this study, K-means clustering algorithm combined with a data mining technique that includes unsupervised learning clustering algorithm is proposed to detect different demand segments among PT users based on their dai...
