【Abstract】 The real time data of traffic and vehicle are the basis of many ITS (Intelligent Transportation System) applications, and the data acquisition has become an important problem in ITS researches. This article introduced an on_board acquisition platform for ITS based on virtual instrument (VI) technology, and described how to design and apply it to proctice. This kind of platform serves an excellent auxiliary measurement and validation platform, which can be used to study on driver’s behaviors to acquire traffic data and to take real_time measurement. The platform also can be used in ITS multifunction experiment vehicle for developing the probe vehicle technology. And VI technologies can make the measurements more convenient and more reliable, which combine advantages of computer and electronic instruments.更多还原
