An infrastructure free, vision based navigation system
The GoTRAX system can be used as an input to driver advisory systems, or the system can be directly used to aid drivers with layout of track-ahead and upcoming signal status. GoTRAX can also be used for over-speed protection and collision prevention.
GoTRAX has no reliance upon GPS and requires no additional infrastructure, only the rails. GoTRAX uses a sensitive low light infra-red camera to detect the rails, points and distance travelled in all operable weather. GoTRAX fuses optical flow distance measurements, and Inertial Measurement Unit (IMU) data, with rail track and point detections to provide precise track identification, location and speed measurement.
