Transport in Turkey
Transport in Turkey is road-dominated and mostly fuelled by diesel. Transport consumes a quarter of energy in Turkey, and is a major source of air pollution in Turkey and greenhouse gas emissions by Turkey.
The TCDD – Türkiye Devlet Demir Yolları (Turkish State Railways) possess 10,984 km of 1,435 mm (4 ft 8+1⁄2 in) gauge, of which 2,336 km are electrified (2005).
There are daily regular passenger trains all through the network. TCDD has started an investment program of building 5.000 km high-speed lines until 2023. As of October 2019, three high speed train routes are running: Ankara-Eskişehir-İstanbul, Ankara-Konya and İstanbul-Eskişehir-Konya.
The freight transportation is mainly organized as block trains for domestic routes, since TCDD discourages under 200 to loads by surcharges.
After almost 30 years without any trams, Turkey is experiencing a revival in trams. Established in 1992, the tram system of Istanbul earned the best large-scale tram management award in 2005. Another award-winning tram network belongs to Eskişehir (EsTram) where a modern tram system opened in 2004. Several other cities are planning or constructing tram lines, with modern low-flow trams.
By 2014, there have been 12 cities in Turkey using railroads for transportation.
- Cities with commuter rail systems: Istanbul, Ankara, Izmir, Gaziantep(very soon)
- Cities with metro systems: Istanbul, Ankara, Izmir, Bursa, Adana
- Cities with light rail transit systems: Istanbul, Ankara, Izmir, Adana, Bursa, Eskişehir, Konya, Antalya, Kayseri, Gaziantep, Samsun, Kocaeli.
- Azerbaijan – via Georgia – under construction
- Armenia – closed (see Kars Gyumri Akhalkalaki railway line)
- Bulgaria – open – 1,435 mm (4 ft 8+1⁄2 in)
- Greece – open – 1,435 mm (4 ft 8+1⁄2 in) (Note: Passenger services as Express of Friendship/Filia suspended from 13 February 2012 )
- Georgia – under reconstruction – break-of-gauge 1,435 mm (4 ft 8+1⁄2 in)/1,520 mm (4 ft 11+27⁄32 in).
- Iran – via Lake Van train ferry – same gauge
- Iraq – No direct link, traffic routed via Syria – same gauge
- Syria – closed – 1,435 mm (4 ft 8+1⁄2 in) (Note: It was suspended after breakout of Syrian Civil War in 29 August 2011)
Road transport is responsible for much air pollution in Turkey and almost a fifth of Turkey's greenhouse gas emissions, mainly via diesel. As of 2020[update] there are many old, inefficient, polluting trucks. Retiring old polluting vehicles by forcing all cars and trucks to meet tailpipe emission standards would reduce disease, especially from polycyclic aromatic hydrocarbons. As of 2014[update], the country has a roadway network of 65,623 kilometres (40,776 miles). The total length of the rail network was 10,991 kilometres (6,829 miles) in 2008, including 2,133 kilometres (1,325 miles) of electrified and 457 kilometres (284 miles) of high-speed track. The Turkish State Railways started building high-speed rail lines in 2003. The Ankara-Konya line became operational in 2011, while the Ankara-Istanbul line entered service in 2014. Opened in 2013, the Marmaray tunnel under the Bosphorus connects the railway and metro lines of Istanbul's European and Asian sides; while the nearby Eurasia Tunnel (2016) provides an undersea road connection for motor vehicles. The Bosphorus Bridge (1973), Fatih Sultan Mehmet Bridge (1988) and Yavuz Sultan Selim Bridge (2016) are the three suspension bridges connecting the European and Asian shores of the Bosphorus strait. The Osman Gazi Bridge (2016) connects the northern and southern shores of the Gulf of İzmit. The Çanakkale Bridge, currently under construction, will connect the European and Asian shores of the Dardanelles strait.
There are three types of intercity roads in Turkey:
– The first is the historical and free road network called State roads (Devlet Yolları) that are completely under the responsibility of the General Directorate of Highways except for urban sections (like the sections falling within the inner part of ring roads of Ankara, Istanbul or İzmir. Even if they mostly possess dual carriageways and interchanges, they also have some traffic lights and intersections.
– The second type of roads are controlled-access highways that are officially named Otoyol. But it isn't uncommon that people in Turkey call them Otoban (referring to Autobahn) as this types of roads entered popular culture by the means of Turks in Germany. They also depend on the General Directorate of Highways except those that are financed with a BOT model.
– The third type of roads are provincial roads (Il Yolları) are highways of secondary importance linking districts within a province to each other , the provincial center, the districts in the neighboring provinces, the state roads, railway stations, seaports, and airports
- Motorways: Motorway 2.225 km (2019)
- Dual carriageways: 17.550 km 
- State Highways 31.021 km (2019)
- Provincial Roads 34.153 (2019)
- Motorway Projects‐Vision 5250 km (in 2023)
Public road transport
There are numerous private bus companies providing connections between cities in Turkey. For local trips to villages there are dolmuşes, small vans that seat about twenty passengers. As of 2010, number of road vehicles is around 15 million. The number of vehicles by type and use is as follows.
- Car 7,544,871
- Minibus 386,973
- Bus 208,510
- Small truck 2,399,038
- Truck 726,359
- Motorcycle 2,389,488
- Special Purpose vehicle 35,492
- Tractor 1,404,872
- Total: 15,095,603

In 2013 Turkey had the tenth largest passenger air market in the world with 74,353,297 passengers. In 2013 there were 98 airports in Turkey, including 22 international airports. As of 2015[update], Istanbul Atatürk Airport is the 11th busiest airport in the world, serving 31,833,324 passengers between January and July 2014, according to Airports Council International. The new (third) international airport of Istanbul is planned to be the largest airport in the world, with a capacity to serve 150 million passengers per annum. Turkish Airlines, flag carrier of Turkey since 1933, was selected by Skytrax as Europe's best airline for five consecutive years in 2011, 2012, 2013, 2014 and 2015. With 435 destinations (51 domestic and 384 international) in 126 countries worldwide, Turkish Airlines is the largest carrier in the world by number of countries served as of 2016[update].
