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.
