Transportation and telecommunications
The flat relief of most of Ukraine presents few obstacles to transportation. Although by European standards the density of the country’s hard-surface road network is low, asphalt-paved highways connect all the regions and large industrial centres. The links between Kiev and Moscow, Odessa–Kiev–St. Petersburg, Moscow–Kharkiv–Simferopol, Uzhhorod–Lviv–Rivne–Kiev, and Kiev–Kharkiv–Rostov-na-Donu (Russia) are highways of particular importance.
The heaviest concentration of railroad trackage is in the Donets Basin and near the Dnieper River, especially its west bank. The largest railroad centres are Kharkiv, Kiev, Dnipropetrovsk, Bakhmach, Yasynuvata, Debaltseve, Lviv, Kovel, and Kup’yansk-Vuzlovyy.
Ukrainian ports on the Black Sea and the Sea of Azov are found at Odessa, Illichivsk, Mykolayiv, Kherson, Feodosiya, Kerch, and Mariupol. River shipping is conducted primarily on the Dnieper and its tributaries (the Pripet and Desna), on the Southern Buh, and on the Danube, which is important in trade with other European countries. Ships on the Danube call at the port of Izmayil, which is accessible to oceangoing freighters and passenger liners. Through the Dnieper-Bug Canal, in Belarus, the inland waterways of Ukraine are joined to the Vistula River basin of Poland and to the Baltic Sea. Efforts to transform the Dnieper into a continuous deep waterway have been furthered by the creation of large reservoirs at hydroelectric stations. The largest ports on the Dnieper are Kiev, Dnipropetrovsk, Zaporizhzhya, and Kherson.
Kiev is connected by air with all the regional centres of the country and with major cities throughout Europe and Asia, as well as with cities in North America and Australia. International airports in Ukraine include Boryspil near Kiev and those at Kharkiv, Lviv, and Odessa.
Since independence, Ukraine has worked to improve its inadequate Soviet-era telephone system. The country is now linked to international fibre-optic and satellite systems. Meanwhile, cellular telephone usage has risen dramatically, and by 2010, cellular subscriptions outnumbered people in Ukraine by almost 20 percent. The rates of Internet use and personal computer ownership lagged behind those of neighbouring countries.
