Using cellphones to measures road defects

A novel system is now available that allows a smartphone to be used to measure road defects. Developed by Grimmer Software, the RoadBump Android application can be used to measure the roughness of a road. This tool can provide estimates of International Roughness Index (IRI) in metric or standard units, without requiring high-cost laser profilers.

A novel system is now available that allows a smartphone to be used to measure road defects. Developed by Grimmer Software, the RoadBump Android application can be used to measure the roughness of a road.

This tool can provide estimates of International Roughness Index (IRI) in metric or standard units, without requiring high-cost laser profilers.

RoadBump uses an Android device's GPS and accelerometer to measure the roughness of a road. It displays a map of the road that was measured, and allows you to zoom in to measure any part of the travelled path. RoadBump produces estimated IRI and Present Serviceability Rating (PSR) graphs. An accelerometer graph shows individual bumps, dips and waves.

The firm said that this tool is easy to use. Activating the unit and driving along the road at normal speed is sufficient to gather road data. A network connection is not required. The unit can be used when travelling at speeds from 32 to 100km/h and is said to have been extensively tested to ensure its accuracy.

Servicing both domestic and international travel, with over 200,000 movements per year, operating without a curfew Brisbane’s main runway is the busiest in Australia. For maintenance, crews only have a limited period of time to determine the pavement condition, normally during the night, making the detection of pavement faults difficult. To resolve this issue, a new high speed pavement scanner was used to rapidly survey the pavem

    Topcon says that its new IP-S2 package combines GNNS positioning capabilities with inertial sensors, while the firm also has a solution for customers wanting to mix and match receiver components. The IP-S2 is a vehicle-mounted, mobile 3D tool that offers precision mapping and surveying capabilities. The package collects data using 3D laser scanners, LIDAR, and/or cameras, and this is then integrated, time-stamped and geo-referenced. The customer can use this assembled data to combine LIDAR point cloud and d
