Development of a Full-Digital and Networkable Multi-Media Based Highway211 Information System, Phase 1

摘要

This report covers the development of a Multimedia Based Highway Information211u001eSystem (MMHIS)> MMHIS extends the capabilities of current photo logging 211u001efacilities. MMHIS can be applied in a state highway department environment. This 211u001eMultimedia-based Highway Information System (MMHIS) utilizes state-of-the-art 211u001etechnologies in digital video, high-speed networking, and the video server. A 211u001edata-synchronization algorithm was developed to dynamically display digital video 211u001eframes along with traditional engineering data sets that contain information such 211u001eas as-built data, pavement conditions and performance, traffic safety, geometric 211u001efeatures, and other infrastructure data. Geo-referencing capabilities were also 211u001edeveloped into MMHIS, so that multimedia data is location-referenced in the 211u001edatabses.
