    <div>Hi Martin,<br>
      <br>
      hmmh, if the speed is somehow calculated to be 0 then the access
      should be set to false making the ferry no longer available. And
      if the speed is not 0 then the exception should not be thrown.<br>
      <br>
      Additionally in this case I see that the unknownSpeed *should* be
      selected but it should be 5km/h (living_street):<br>

      <br>
      Maybe you can debug this a bit and tell if the speed of the edge
      is 0 or not and why.<br>
      <br>
      Also when switching branches make sure you remove the target
      folders and/or rebuild in your IDE.<br>
