videolog and stampp
VideoLogging is a term PennDOT uses to describe its automated collection of pavement conditions and roadway imagery. The VideoLog data is collected on all state-owned bituminous and jointed concrete pavements by a vehicle called a VideoLog Van or Video Van. The van itself doesn't collect video like that seen in a movie, but instead collects a series of individual pictures at set intervals that are sequenced together. There are two key benefits gained with VideoLogging:
- Safety: Conducting manual pavement surveys can present hazards for PennDOT personnel because the process involves traveling on the roadway shoulder at slow speeds. VideoLogging replaces the need for frequent manual surveys, so it is much safer.
Efficiency: VideoLogging provides panoramic images for personnel to view, instead of having to physically travel to a location to view pavement conditions.
Systematic Technique to Analyze and Manage Pennsylvania's pavements (STAMPP)
Manual distress surveys are performed by two-person teams consisting of a driver and an evaluator, as they travel in a vehicle slowly along the shoulder. The type, severity, and extent of continuously reinforced concrete (CRC) pavements, unpaved roads, shoulder, guide rail, and drainage conditions are noted on standardized survey forms developed for use on laptops or tablets, and then uploaded and stored in the Roadway Management System (RMS). Manual surveys are typically performed by temporary Engineering, Scientific, and Technical Interns (ESTI) that are hired to perform the work during the summer months. The Engineering Districts are responsible for performing the shoulder, guiderail and drainage surveys while RITU manages the entire STAMPP program, conducts the CRC and unpaved road surveys, and provides QA of the District surveys.
