Can you describe a bit more precisely what you wish to do? It sounds
like perhaps you have point samples of a vehicle's travel and you want
to estimate from those the most likely path it actually followed along a
road network? If that's your aim, you need to familiarize yourself with
the challenges and rewards of route-matching, e.g. using OSRM:
https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fproject-osrm.org%2F&data=02%7C01%7CNEARC-L%40LISTSERV.UCONN.EDU%7C1f144d9f3f764364483208d6e8928946%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C1%7C636952113401656341&sdata=By45tM%2FUIog1%2BWMzI6Y70%2BnglEuIgLc2%2FhEBfLHSNi4%3D&reserved=0
It's been a few years since I worked with this stuff, but I think the
general approach is still reasonably well presented in this paper by
some of the early researchers:
https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ismll.uni-hildesheim.de%2Flehre%2FsemSpatial-10s%2Fscript%2F6.pdf&data=02%7C01%7CNEARC-L%40LISTSERV.UCONN.EDU%7C1f144d9f3f764364483208d6e8928946%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C1%7C636952113401656341&sdata=X0duAqSdz%2FcX25wVt1CI4DDANDWOwxPpXiwSjx1yTdQ%3D&reserved=0
You don't have to master that material to use OSRM, but it's good to
understand some of the challenges involved in what is a more or less
constrained estimation (educated-guessing) problem whose success depends
on the quality (density, accuracy, and precision) of your point data.
If you have some other goal in mind, please try to clarify.
