Is your feature request related to a problem? Please describe.
Say I have three points I want to match: A at 10:01am, B at 10:02am, and C and 10:03am. Say the map-matched path/geometry is a line of 10 points - what I want to do is infer the time at each point e.g. was the time for the 5th point 10:02.05am or 10:02:59am etc. The main problem with trying to do this manually myself is I don't think I can associate each of my three input points to the one of the 10 points e.g. I don't know if point B was matched to the 2nd or 9th point etc., and hence can't infer times myself (by calculating distance etc.)
Describe the solution you'd like
In python, either:
Built in support for doing this so that e.g. if a Trajectory is provided, the timestamps are also inferred. However, this may be messy as inferring time depends on speed limits etc.
Something similar to result.indices but which points to the index of the point in the resulting geometry of points, not edges. Then I could work backward myself as outlined above. Having access to more point/line metadata may help too (e.g. OSM speeds etc.).
Describe alternatives you've considered
I could manually reconstruct graphs myself, but that's pretty icky! I've had a look around and search but didn't seem to see anything solving this - apologies if I missed it!
Additional context
Ultimately, it's for pretty animations of routes, which requires knowing the time at each point.
