PaVision® Automated Pavement Condition Assessment System
Finding a safe, reliable, and affordable pavement condition assessment system is a challenge for many agencies. While Federal and State highway agencies, metropolitan planning organizations, cities/counties, and tollways all have a need for assessing pavement conditions, typically only larger organizations have sufficient resources to acquire state-of-the-art digital image and/or laser crack measurement systems and automated distress identification technologies. ARA developed PaVision® to provide agencies of all sizes an affordable, easy-to-use system to assess pavement conditions.
Current digital image and laser crack measurement systems can cost upwards of $1M and are owned/operated by a select number of vendors worldwide. PaVision can be purchased or leased at a fraction of the cost, and it can be installed quickly and operated by agency staff.
PaVision uses commercial off-the-shelf hardware and components that can be acquired and updated easily. The PaVision equipment is easily transported via hand-carried cases and mounted to any standard tow hitch. The system includes a downward-facing camera for pavement images, a forward-looking camera for right-of-way mages, a GPS receiver, an accelerometer for measuring pavement ride quality, and a miniature portable computer. All of the equipment is mounted on weatherproof housings that are secured to a vertical hitch post. One person can assemble and attach the system to any vehicle with a standard tow hitch in a matter of minutes.
The collected images and data can be stored on a local system hard drive or uploaded to the cloud in real time. Images are then analyzed automatically to quantify pavement distress and ride quality. The resulting product is a sectioned database of geo-referenced pavement distress data, ride quality data, and condition index ratings that are displayed on color-coded, Google Earth maps and associated tabular summaries. The comprehensive data set allows the agency to accurately evaluate pavement conditions network-wide, identify pavement repair requirements, and effectively communicate conditions and future needs to stakeholders.
The PaVision system is an innovative technology that offers transportation agencies of all sizes the ability to cost-effectively assess pavement conditions and implement pavement management practices. The system is available for purchase or lease, and it does not require any software installations on the user’s network. Analyzed results can be provided in days.
