摘要：	Intelligent transportation systems (ITS) represent the application of information processing, communications technologies, advanced control strategies, and electronics to the field of transportation. In other words, ITS means electronics, communications, or information processing used singly or in combination to improve the efficiency or safety of a surface transportation system. Integration of ITS into the transportation system requires justification along with other infrastructure improvements. To accomplish this, the basic level of ITS at which benefits/costs have been established is 'the market package', a collection of equipment or technologies that work together to deliver a particular ITS service. The market packages listed. Another concept, 'the market area', is a collection of market packages that serves a group of buyers and users of ITS who have similar needs or objectives. The world of ITS is seen to be comprised of nine market areas. ITS strategies differ from traditional transportation improvements in that they are operationally and information oriented, and aimed at events and unusual conditions. Because of the differences between the impacts of ITS and those of traditional transportation improvements, there is a growing need for new systematic evaluation methods to show the impacts of ITS projects.
