From capture, to clearance.

What is Clearance Management? Clearance management is the analysis of load throw, mounting position, track geometry, dynamic behaviour and survey scan information to obtain a distance between the vehicle and infrastructure that allows safe operation.

To put it simply, by understanding your network correctly, and applying clearance assessments, you can make your railroad more efficient, safer and desirable.

How does the solution work?

Can you utilize existing LiDAR data

Yes, Cordel engineers are able to convert 3rd party LiDAR data into clearance surveys in most situations. Please get in touch to understand the minimum data we require

What clearances can I assess?

It is possible to assess clearances to infrastructure, clearances between passing vehicles and platform gap clearances. Clearances can be assessed for individual locations, route sections or entire regions.

Are Assets manually extracted?

Cordel use Machine Learning and AI to automatically process and classify survey data. Please read our case study where we go into this in more detail

Can I assess High and Wide loads?

Yes, Not only is it possible to assess standard vehicles (such as Plates or Gauges), but it is also possible to assess non-standard shapes and other types of railway traffic such as high and wide loads.

What hardware do you use to Capture LiDAR data?

Cordel manufacture our own LiDAR equipment

What information do I need to run clearance assessments?

Users will have to be able to specify the shapes of non-standard loads and where they need assessing. The software has access to survey data as processed by Cordel. Settings are normally configured for different networks.

How do you access clearance surveys?

Survey recorded are managed and stored on the cloud. This provides instant access to your organisation and seamless integration with the D/Gauge clearance software.

How can the software optimize clearance?

The software includes features to adjust track alignments or infrastructure modifications.
