The app also captures photos or videos of the road with geo references (GPS). Roadroid also provide apps for Road inventorys, inspections and traffic counting. We also offer a wireless and battery operated traffic counting and classification sensor. Collected data is viewed and managed in a web based Road Data Management System.
