</span>access=destination is IMHO a bad example for this. Penalizing those<br>
edges heavily will cause OSRM to very hard try to use the next<br>
possibility to leave the access=destination segments or to enter<br>
them at the very last possibility. The cost for using<br>
access=destination roads is not proportional to the amount of distance<br>
you travel on that road, but its a one time cost entering the<br>
road/segment/area.<br>
<br>
In the end most of the time access=destination based roads build a<br>
subgraph e.g. multiple interconnected roads and the area itself<br>
is access=destination.<br>
