Here's what I was expecting

The route avoiding a way with tag hgv=no

Thanks for reporting this! I can confirm the problem and I will look into it.

[aoles]

Access restrictions for hgv driving profiles are currently not resolved on ORS maps because of a missing vehicle_type parameter under route options of the request. The restrictions are evaluated by the HeavyVehicleEdgeFilter which is enabled only when this parameter is set.

I couldn't find any recent changes in handling of vehicle_type in the backend. @TheGreatRefrigerator have there been any changes to the hgv subprofiles in the maps client maybe?

[TheGreatRefrigerator]

have there been any changes to the hgv subprofiles in the maps client maybe?

No recent. See GIScience/openrouteservice-app@8c54a64

I've changed it back then to only add the vehicle_type if there are actual vehicle restrictions (length, width) set.

The documentation is kind of ambigous for this, as it says the default value for vehicle_type is hgv
which would make sense if the driving-hgv profile is chosen.

@aoles do you think it's feasible to have vehicle_type set to hgv by default and only read other vehicle types if they are passed with this parameter?
in here i guess

[aoles]

We certainly could introduce a default value for vehicle_type. I don't think this has ever been the case before, though, so I'm not sure why the documentation would say otherwise.

[koebi]

I'd assume that the changes in #1054 also fix this issue, but it seems that they don't, as the query above still happily routes over the hgv=no-way as well as an example query will route via Saupfercheckweg mentioned in #1006.

[aoles]

#1054 fixes the problem that setting both vehicle_type and options.profile_params.restrictions was required in order to resolve vehicle_type-specific access restrictions. The remaining issue observed in the maps client originates from the fact that vehicle_type is not set by the client unless some vehicle parameters are used. As long as we want to have CH as the default routing algorithm setting a default vehicle_type value seems unfeasible as it would require the use of a flexible routing algorithm different than CH.

[koebi]

It seems a bit unintuitive that hgv access restrictions are not checked when using the driving-hgv-profile.
In fact, the API docs state that the default vehicle_type is hgv, so at least that should be changed.

IMO, when using the hgv-profile without any further settings, OSMs hgv:*-access restrictions should be considered.
If not, what even is the difference between the hgv and the car profiles?

[aoles]

Thanks, these are all fair points!

IMO, when using the hgv-profile without any further settings, OSMs hgv:*-access restrictions should be considered. If not, what even is the difference between the hgv and the car profiles?

While hgv-specific access restrictions are certainly important, there is still a number of other differences between these two profiles. Apart from a distinct set of default road speeds, the main difference between car and hgv profiles is that for the latter one the recommended weighting uses additional prioritization of certain road types.

It seems a bit unintuitive that hgv access restrictions are not checked when using the driving-hgv-profile. In fact, the API docs state that the default vehicle_type is hgv, so at least that should be changed.

I couldn't agree more on this. In particular, I'm not sure where the statement in the API docs about the default vehicle_type = hgv comes from? As far as I could tell this has never been the case. There are, however, some technical constrains which need to be taken into account when settling on a default value, see below.

The main challenge here is to take these default hgv restrictions into account when performing routing with CH which is the default algorithm when no additional parameters are set. This is not entirely easily to implement because CH does not allow for setting any additional edge filters, both during contraction and routing. I've solved this by introducing an additional HgvAccessWeighting to the pipeline which acts as a wrapper calling the HeavyVehicleEdgeFilter before the actual call to the underlying weighting. This allows to exclude edges with hgv:no from CH routing while still keeping them in the main graph available to the rest of the routing algorithms.
