12.1 Stage Route Preview

Static map, significant corners highlighted:

12.2 Segmented Route

1km route sections, aligned to read left to right; significant corners highlighted.

12.3 Speed Estimates

Estimates of speed along the route according to a very simple acceleration model.

Kilometer section speeds (kmtime is time in seconds to complete that segment; avspeed is in km/h):

Anticipated stage time: 7m 39.5s

Speed profile chart: this chart shows the anticipated speed over distance into route on a per kilometer basis (the green area is flat out, the pink is the sort of slow you see at a hairpin):

12.4 Elevation and Convexity Index into Route

Elevation and significant curvature vs distance into stage:

(Note that this uses a different curvature measure to the route plots; specifically, the curvature measure used here is the convexity index.)

Elevation delta signature — order the severity of height changes over each 10m section of the stage:

Split section elevation profiles can be found in the stage km section summary table.

12.4.1 Left and Right

How does the stage vary in terms of left and right turns?

Order the severity of right and left turns over each 10m section of the stage:

Kilometer segment convexity index signatures can be found in steg stage km section summary table.

12.4.2 Sinuosity and Straightness

Sinuosity and straightness are technical measures with specific defintions. They may or may not be that useful for route analysis in their current form. The intention is to try to find ways of identifying variously “interesting” kilometer stretches.
