@Marcella0202 thank you for your request.
Providing live traffic is money intensive and not coverable with our free API quotas (currently). If you would like to use statistical traffic, we have an integration of HERE statistical traffic that you can use with your own hosted openrouteservice instance. You would need to buy the data from Here, of course. Be aware, since only very few have the resources to even buy statistical traffic data, we did not have many requirements to document this well in our public documentation.
Please reach out to us if you’re planning to use it, and we can see how to show you in the right direction.
