摘要：	This report covers the development of a Multimedia Based Highway Information System (MMHIS)> MMHIS extends the capabilities of current photo logging facilities. MMHIS can be applied in a state highway department environment. This Multimedia-based Highway Information System (MMHIS) utilizes state-of-the-art technologies in digital video, high-speed networking, and the video server. A data-synchronization algorithm was developed to dynamically display digital video frames along with traditional engineering data sets that contain information such as as-built data, pavement conditions and performance, traffic safety, geometric features, and other infrastructure data. Geo-referencing capabilities were also developed into MMHIS, so that multimedia data is location-referenced in the databses.
