There are daily regular passenger trains all through the network.[8] TCDD has started an investment program of building 5.000 km high-speed lines until 2023. Multiple high speed train routes are running, including: Ankara-Eskişehir-İstanbul, Ankara-Konya and Ankara-Sivas lines.
The freight transportation is mainly organized as block trains for domestic routes, since TCDD discourages under 200 to loads by surcharges.
Urban rail
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.
Road transport is responsible for much air pollution in Turkey and almost a fifth of Turkey's greenhouse gas emissions, mainly via diesel. It is one of 3 G20 countries without a fuel efficiency standard.[11] As of 2020[update] there are many old, inefficient, polluting trucks.[2] Retiring old polluting vehicles by forcing all cars and trucks to meet tailpipe emission standards would reduce disease, especially from polycyclic aromatic hydrocarbons.[12] As of 2014[update], the country has a roadway network of 65,623 kilometres (40,776 miles).[13] 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.[14][15] 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.[15] 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.[16] 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 1915 Çanakkale Bridge (2022) , connects the European and Asian shores of the Dardanelles strait.
As of 2022[update] fuel quality and emissions standards are not as good as those in the EU.[17]
In 2023 the World Bank said the government should plan and subsidize the rollout of public electric car chargers, particularly because so many people live in flats. They said that a subsidy would provide environmental and social benefits. They also said that cities should set an end date for diesel buses.[18]
– 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
As of 2023, there are 471 tunnels (total length 665 km)[21] and 9.660 bridges (total length 739 km)[22] on the network.
Public road transport
There are numerous private bus companies providing connections between cities in Turkey.[23]
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.[24]
Escooter rental is available in some cities,[28] and escooters can be used on cycle paths, and on urban roads without cycle paths where the speed limit is below 50 kph.[29]
Car ownership
As of 2020[update] over half the registered motor vehicles are cars - about 12.5 million - of which 4.7 million are diesel fueled, 4.7 million LPG, and 3 million gasoline.[30]
Transport emitted 85 megatonnes of CO2 in 2018, about one tonne per person and 16 percent of Turkey's greenhouse gas emissions. Road transport dominated transport emissions with 79 megatonnes, including agricultural vehicles.[45]
