Automation Techniques for Digital Highway Data Vehicle (DHDV)

This paper describes the development of a real-time multi-functional system for roadway data acquisition and analysis, particularly for pavement surface distress survey and roadside asset management. This system, Digital Highway Data Vehicle (DHDV), combines the technologies of laser illumination based digital imaging, inertial profiling and Global Positioning System (GPS) mapping into an integrated system to accomplish the multiple tasks of survey and management for roadway data. The resolution of the pavement images is 1-mm in both longitudinal and transverse directions with the use of high resolution line cameras covering the entire pavement of a single lane. The pavement distress analysis and road sign inventory can be conducted in real time. The system utilizes pattern recognition, image analysis technique and target tracking for performing multiple tasks through parallel processing. Algorithms are presented with the emphasis on the real-time processing of raw data streams in a parallel array of processing cores.
