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 countries. To overturn this situation, deregulation of the rail freight which could bring more competition, thus efficiency, has been tried in different countries in the world, including the EU region. As a candidate for EU membership, Turkey has also developed the legal framework for deregulation of the rail freight sector, which has been put into action in 2017. However, there has been no predictions on the potential impacts of this reform, so far, which is the main focus of this study. Due to the lack of disaggregate freight data from various modes (road, rail, etc.), performing a traditional four-step analysis with mode choice model is very challenging in developing countries like Turkey. Thus, evaluation of the effects of rail freight deregulation can be only achieved by monitoring the trends and shifts in the total rail commodity flow data, as proposed in this study. Using the digitially vi recorded commodity flow data for 4 years period before the deregulation (2011-2014), two years of transition period (2015-2016), which included major renovations along many rail corridors, and first two years after the reform (2017-2018), it was possible to determine the spatial distribution of the major rail freight demand in terms of net-tonnes in Turkey, using Geographical Information Systems (GIS). Similarly, cost information was used to determine rail corridors with higher revenue levels. Aggregation of station level freight and revenu data enabled the determination of the city-based total production and attraction values, which was also determined for 20 commodity types defined in (NST 2007). While before analyses showed that the rail freight demand in Turkey was distributed unevenely over the geograph, as it was mainly governed by the location of natural resources and major heavy industrial settlements (i.e, steel manufactoring factories, etc.). The major shifts to private sector after deregulation are also observed along these corridors, where single commodity type is carried in large volumes.

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...
Evaluation of Condition States of Bridge Elements Based on the Intensity of Different Damage Types
Akgül, Ferhat (2012-10-19)
Transportation infrastructure facilities are the essential components for the continuous development of the economics and community well-being of any country. Maintaining such facilities at all times is a difficult task for service authorities. To assist in conducting such a task, bridge management systems (BMSs) have been developed for effective asset management. This paper presents a novel technique for evaluation of condition states of elements based on the intensity of different damage types. Damages of...

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...
Design and implementation of a multimodal transportation cost analysis model for domestic lignite supply in Turkey
Demir, Eylül Ceren; Karpuz, Celal; Demirel, Nuray (2012-11-01)
Transportation cost is the dominant cost and accounts for almost half of the total mining cost in surface mining. Therefore, determining transportation cost is critically important for the economic feasibility of mining projects. Turkey produces around 85 million tons of lignite per annum. The biggest state-owned company, Turkish Coal Enterprises (TKI), accounts for 43 per cent of the country's total lignite production. Around 85 per cent of the produced lignite is used in power plants for electricity gener...

Transportation sector is one of the major emitters of greenhouse gases due to high consumption of fossil fuels in passenger and freight transportation. In recent years, high speed rail systems (HSR) have become an important policy option for intercity transportation in many countries, including Turkey, as they have relatively low emissions impact. Currently, the total HSR network in Turkey extends to 1213 km and connects 7 cities mostly located along a main HSR corridor. Annual ridership of the first two li...
