Allow flag “access=private” in vehicleprofile

[kashortiexda]

Hi, I stay in an area that I s designated with flag “access=private” . The navigation won’t start at my location and takes me all sorts of places except to/from the area where I stay.
I have tried all sorts of combinations in navit.xml vehicleprofile
Any pointers on how to access these areas (ie allow access=private) or at least NOT avoid areas marked as access=private

Not sure how that is currently being implemented in Navit, but deciding whether it’s OK to use a certain way with access restrictions such as “private”, “customers”, “destination” etc. is complex.

access=private means this way is OK to use this way if you are the owner, or you have permission from the owner or someone authorized to give such permissions on the owner’s behalf. The tricky part is that you would have to tell your navigation system which ways you have this permission for, so it can route you along these ways as needed but not send you on a private road you’re not authorized to use.

A workaround would be to treat access flags like private, customers in a manner similar to access=destination – assume that the user has the right to use these ways if they are the last stretch to the user’s destination or the first stretch from there. Such ways may be used if they are the nearest way from the destination, or from the current location. They can only be used at the start or at the end of the route, even multiple ways, but not in between. Once the vehicle goes from a public to a non-public way, it stays on non-public ways until it reaches its destination.

However, I can’t tell off the top of my head how Navit currently handles access=destination. Does anyone happen to know?

In maptool/osm.c for access, only destination is handled:

    if (! g_strcmp0(k,"access")) {
        if (g_strcmp0(v,"destination"))
            flagsa[access_value(v)] |=
                AF_DANGEROUS_GOODS|AF_EMERGENCY_VEHICLES|AF_TRANSPORT_TRUCK|AF_DELIVERY_TRUCK|AF_PUBLIC_BUS|AF_TAXI|AF_HIGH_OCCUPANCY_CAR|AF_CAR|AF_MOTORCYCLE|AF_MOPED|AF_HORSE|AF_BIKE|AF_PEDESTRIAN;
        else
            flags[0] |= AF_THROUGH_TRAFFIC_LIMIT;
        if (! g_strcmp0(v,"hov"))
            flags[0] |= AF_HIGH_OCCUPANCY_CAR_ONLY;
        level=5;
    }

For destination AF_THROUGH_TRAFFIC_LIMIT is set in flags[0].

So changing if (g_strcmp0(v,"destination")) to if (g_strcmp0(v,"destination") || g_strcmp0(v,"private")) should achieve what you want.

You need to build maptool and create your map from scratch using the new maptool.

@OLFDB thank you, this helped fix it.
