Friendswood is evaluating its streets with a new, modified 15-passenger van.
The city’s new Road Service Tester van has lasers, distance measuring instruments, accelerometers and rate gyroscopes, inertial navigation-based GPS and high-resolution digital cameras that will cover every city-maintained street in Friendswood.
The instruments collect objective pavement surface distress data, roughness and rutting, city staff said.
After the van collects data, the staff determines where a stretch of road is on a life-cycle curve. The staff can prioritize and schedule pavement repair projects.
The data can also help in making budget proposals.
A trained visual inspector conducted the previous Friendswood citywide survey in 2008.
