摘要：	National standards are especially critical for deployment of intelligent transportation systems (ITS). The core purpose of ITS is to improve communications so that localities and regions are linked together in a way that results in an improved transportation system. The National ITS Architecture provides a common structure for the design of ITS. A 1996 survey found a desire for quick action to set standards on several high-priority areas: the National Transportation Communications for ITS Protocol (NTCIP) and Transit Communications Interface Protocol (TCIP), which address systems such as dynamic message signs, traffic signal controllers, environmental-sensing stations, highway radio advisory, closed-circuit television to monitor traffic, freeway ramp meters, traffic/transit management center-to-vehicle interfaces, and traveler information services; the Location Referencing Message Set; Commercial Vehicle Information Systems and Networks (CVISN); Dedicated Short-Range Communications (DSRC); and data dictionaries and message set templates. The Transportation Equity Act for the 21st Century (TEA-21) required the U.S. Department of Transportation (DOT) to submit a report to Congress by June 1, 1999, identifying critical ITS standards and specifying the development status of each standard identified. DOT is now moving into the process of testing the standards. The ITS Standards Test Team has identified about 55 standards to be tested. The remainder, such as data dictionaries, were deemed not testable.
