Where are sub-threshold delays accumulated most?

Category: Operations
Capabilities: Sub-threshold Delay Calculation

Knowing this, Signaller can review regulation policy to minimise delays.

Knowing this, Timetable Planner can review for any unachievable dwell or SRT.

Knowing this, Station Manager can review for any re-occuring excess dwell delays.

 

JNCTION can get accurate to-the-second insights by analysising train movements data from TRUST and SMART.

 

Difficulty: Low 

For a specific location the method can be developed relatively quickly, depending on the complexity of the location. Once set up, insight regarding right-time departures can be generated and presented to interested stakeholders for action. 

Data: Available 

In most cases, JNCTION has obtained and processed the required data to solve this problem. 

Scalability: High 

The methodology could be replicated across the network easily but would need some manual testing and adjustments for location specific nuances.  

Maturity: Medium 

Amey Consulting’s QUARTZ specialise in sub-threshold delay analysis. However it is more for operational real-time use at stations rather than allowing SRT, regional and/or historical analysis.
