There’s a lot more to Roadvista’s 922

First published in Intertraffic Innovation News - May 28, 2020

RoadVista’s model 922 hand-held field retroreflectometer is one of the industry’s leading instruments for road sign retroreflectivity measurements. But the company points out that the instrument is a whole lot more, with all the features needed for a complete asset management database. The 922 has the ability to record up to 17 different data points.

With versions meeting CEN and ASTM requirements, the system utilises an annular collection geometry. This geometry is advantageous to field instruments because the orientation of the instrument on the sign is not critical, reducing operator fatigue and making it easier for the operator to get a sign measured. Not only is retroreflectivity measured, the 922 also records the date, time, GPS location, ambient temperature and humidity, pass/fail criteria, and many other user-selected fields and comments.

For data management, RoadVista has partnered with a half-dozen different companies to develop asset management and GIS apps for various platforms. This way, users are not tied down to a specific programme, and providing more flexibility and the ability to integrate the instrument into a user’s existing database. The 922 is compatible with Trimble systems, Go-Evo MESH, as well as others. For users without sophisticated database systems, the 922 comes with software to create spreadsheets and GIS map files included. RoadVista says the system is so robust, recently one government agency reported that the 922 was used to inventory their signposts without any retroreflectivity data, using all the information that can be entered into the 922.
