Maps APIs Python client library

https://github.com/googlemaps/google-maps-services-python The directions API lets you specify time, to give better traffic estimation. That gives you rough transit time, so add on your overhead and then a multiplier to add slack for unforeseen circumstances (this can be tuned down later).

Lol if this isn’t sufficient documentation for you I don’t know what to tell you: https://github.com/googlemaps/google-maps-services-python#usage

First of all, Google provides a python library to interact with it's maps/directions API. There is a documentation, however for more specific information (eg. output formats) you will have to refer to the General Google API documentation.

You could also look to this official library from google (https://github.com/googlemaps/google-maps-services-python), it's easier to use, but if you're learning doing it yourself like you are right now has its merits (learning).
