The survey trolley provides a convenient way of lane surveying when doing vehicle-to-lane measurements with the RT-Range S. The RT-Range S line survey tool software makes creating straight and curved lines simple.
Capture lane markings and turn them into a map
For lane tracking tests, OxTS has a dedicated survey trolley that can be used to survey lane markings and includes software to capture each line and add it to a map.
The survey trolley is designed to keep the GPS antenna high, so the accuracy is not reduced by multipath (caused by reflections from a person above it). The survey trolley can accommodate a battery, laptop computer and an RT.
The survey is done by using one of the survey trolley wheels as the measurement point to provide the best accuracy.
Straight or curved lanes
The line survey software can be used to store the straight or even curved line measurements into a file and turn it in to a map. The map can be downloaded in to the RT-Range S and then the lane measurements begin.
