Hello everyone,
To shorten the lab session, for the last part, you are not required to look up road characteristics on OSM. The weather data should be sufficient. If you have already done it, or choose to do it anyway, bonus points will be awarded.
Also, do not expect to have a perfect fit for the travel time and speed distributions. The data set is big and it's real data. Comment on why it does not match.
Have a great day,
Guillaume
