The road transportation situation in Korea is much more difficult than those of advanced countries due to poor infrastructure. Many of the nation's roads and most urban roads are badly clogged. Congestion continues to increase even though the government has been working hard to build more roads as much as possible. Overall mobility is highly threatened, especially in urban areas. The speed is reduced to two thirds every five years.
Safety continues to be a prime concern.
A campaign to reduce the traffic accidents to half this rate has been started from this year. Public transportation systems due to shortage of utilities and poor services are seen as an unattractive alternative to driving. Low rate of subway usage in passenger traffic also helps to worse the road transportation. There are also other costs including needless waste of energy, emission of pollutants and loss of productivity. Hence, goals of ITS development is established to solve these problems and lifting a bright vision to the future.
