Metro Line Curvature
description
description
This dataset shows the results of a curvature analysis for the metro lines (in the sample example of Paris Metro's line 14).
The curvature radius is computed on each segment of the metro line's geographical path. The curvature radius on each segment is interpolated from the curvature radius on the segment bounds since only a series of points on the path is available. Please check out our tutorial for a detailed explanation of the calculations.
Benefits
Benefits
With the Metro Line Curvature dataset you will be able to :
- Give a severity score to each curvature and when combine with speed and laod profiles
- Anticipate vehicle maintenance by knowing better the severity score of their routes and mechanical stresses they undergo
- Anticipate costs and reduce them to the necessary if possible
Use Cases
Use Cases
Thanks to this dataset, a public transport organisation can estimate the maintenance of its vehicles and infrastructure and therefore plan, prioritize and budget the maintenance activities accordingly.
For public transport OEMs or Tier1, it might help estimate the line operational cost thanks to benchmark with already existing lines.

Dataset Features Definition
Dataset Features Definition
The curvature radius at a given point (column "circumradius") is approximated by the circumradius of the triangle formed with the surrounding points (see metro curvature tutorial). It is arbitrarily set as 100 km for the first and last points of the line.
The curvature radius of a section of the line (column "curve_radius") is defined as the harmonic mean of the curvature radius of the current point (as defined above) and the next one.
