HGV access restrictions

[aoles]

Access restrictions/permissions doesn't seem to be properly resolved for driving-* profiles. Consider the following example for driving-hgv withvehicle_type=agricultural:

https://maps.openrouteservice.org/directions?n1=49.465&n2=8.658385&n3=15&a=49.469532,8.658686,49.464359,8.660789&b=4d&c=0&k1=en-US&k2=km

The direct route is not found even though the way has the OSM tag access=agricultural.

Interestingly, the same route is returned for driving-cardespite that these roads are restricted to agricultural usage: https://overpass-turbo.eu/s/AL3. UPDATE: access=agricultural alone just permits agricultural usage without restricting it for regular traffic unless used in combination with motor_vehicle restrictions such as

Things get even more funky when profile restrictions, such as hazmat=true are enabled. Then the route above changes the one below, even though there are no hazmat restrictions in this area! Seems to be related to #209 and #211.

UPDATE highway=track below tracktype=grade1 are excluded from the road network by HeavyVehicleFlagEncoder based on maxTrackGradeLevel. While this can be specified in the encoder options in app.config, the defaults for CarFlagEncoder and HeavyVehicleFlagEncoder are 3 and 1, respectively.

Consider revising these settings to allow routing of agricultural or forestry vehicles on lower grade tracks.

Roads with access=agricultural are filtered out by both CarFlagEncoder and HeavyVehicleFlagEncoder because of agricultural being in restrictedValues. However, ways tagged with multiple values such as agricultural;forestry are not picked up by this filter which explains why it's still possible to still go around from A to B in the example above.

Consider keeping ways tagged as agricultural for hgv profile because of agricultural and forestry subprofiles.

Interesting test cases:

• just access=agricultural or motor_vehicle=agricultural 🚗
• agricultural=yes and motor_vehicle=agricultural 🚗
• agricultural=yes and motor_vehicle=destination 🚗
• agricultural=no 🚗
• hgv=agricultural and motorcar=yes 🚗

What is the status of this as in the new release it does not go down the direct way?

What is the status of this as in the new release it does not go down the direct way?

It does not route down the direct way because it is of tracktype=grade3 as mentioned previously:

UPDATE highway=track below tracktype=grade1 are excluded from the road network by HeavyVehicleFlagEncoder based on maxTrackGradeLevel. While this can be specified in the encoder options in app.config, the defaults for CarFlagEncoder and HeavyVehicleFlagEncoder are 3 and 1, respectively.

The actual test cases for #366 have been listed in my last post above.
