Taichung has a range of options for tranport in and out of the city, both public and private, that put most similarly-sized cities world-wide to shame. For links to other cities, there is a wide variety of highway bus companies, offering everything from budget seats to giant plush lazyboy-style chairs with private video screens, video games and massage functions. For rail travel, there is the efficient traditional Taiwan Rail network, plus the more recently-constructed Taiwan High Speed Rail network that offers connections to Taipei and Kaohsiung in about an hour, plus links to Taoyuan (where there's a shuttle bus to the international airport), Hsinchu, Chiayi and Tainan. Taichung's Ching Chuan Kang (CCK) International Airport also offers regular international flights to Hong Kong, Ho Chi Minh City, Shanghai and other Asian/mainland Chinese destinations. Inside the city, Taichung is known for relatively good traffic conditions. A new TTJ city bus system has recently been put in place that is efficient and easy to use. Taxis are plentiful and inexpensive. Over the next several years, Taichung is also constructing a Mass Rapid Transit system.
