Route Assessment & Asset Logging

The first chapter of our rail and signalling tools allows user to travel the route and plan the design options. Chainages are correlated with either mileages or meterages as supplied by the project or generated by Gioconda.  Positions of existing or proposed assets can  measured along with clearances etc. Asset positions can be logged and recorded and editable screen captures allow for easy communication.

Key Benefits

  • Manage several projects with any number of routes
  • Multiple users each with their own discreet references and logs
  • Switch between original footage & proposed scheme for assessment and planning
  • Images, files and associated notes can be linked to any known or proposed location
  • Screen capture with notes superimposed
  • Basic height, offset & point to point measurements
  • MRD calculation
  • Forms the basis of the Signal Sighting Tool

The Route Assement process:

 Filming:

The G-RAT (Route Assessment Tool) can use high definition footage from a wide variety of sources, however, Gioconda prefers to use its own skilled camera operators to ensure the very best quality footage. Our bespoke camera rig obtains a viewpoint close to the driver’s eye line, without impeding their actual view during filming. A calibrated set-up ensures that measurements and overlays are accurate and repeatable.

Chainage Correlation:

Once route filming is completed, GPS data and known locations are associated to specific frames – this is key to accurate chainage measurements. However, a common problem is the inaccuracy and differences between chainages used by the different design disciplines. The G-RAT system goes some way to highlighting these errors and our internal set-up tools are unique in that we can either work to true distance travelled (PWAY meterage) or a derived chainage (Schemeplan meterage). In all cases the measurements are in metre units.

The Route Assessment Tool (G-RAT)

Utilising the HD footage, the user can check proposed locations for new installations and associate screen captures (with overlaid sketches & notes) to this recorded location. On site photographs or other documents can also be linked with these locations using the object management functions.

The G-RAT can be used as a simple (low accuracy) survey tool for Asset Logging. The ruler function enables visual offset & height measurements to be taken as part of the route assessment task. Surveying the position of Signals, LOCs, & trackside assets is very simple and can help to reduce the content required by detailed on site survey. Typically the design team will use the G-RAT to assess the position of proposed signalling prior to issuing draft Scheme Plans & Sighting Forms. Through this process it is possible to reduce the iterations of schemeplan issue and move to a SSC earlier. The G-RAT is an ideal tool for Grip stages 2 – 4 scheme development.

Object Management

When preparing for a desktop signal sighting session we recommend the use of the Object Manger module. Through this section the user can associate relevant files to preset locations in the HD video. Images, Documents, Drawings, SSFs etc can all be stored on the database allowing easy access to these reference items at meetings & SSCs.
