摘要：	Advanced Traffic Management Systems (ATMS) depend on good-quality digital maps and spatial databases. Concerns over the availability of digital maps and spatial databases for ATMS`s in the United States were initially raised in early meetings of IVHS America ATMS committee. While there has been little argument regarding the important role of the private sector in providing ``value-added`` data for sale to public and private parties, the IVHS community has since been engaged in a lively debate over the appropriates roles of the public and private sectors in providing ``base data`` for the nation`s Intelligent Vehicle and Highway Systems. This paper summarizes the activities of the ATMS Committee over the past 1 1/2 years and offers recommendations for next steps to be taken toward laying the foundations for efficient and effective deployment of digital map and spatial database resources for use in advanced traffic management systems.
