title: Google maps API: ignore seasonal restrictions in DirectionService request
body: <p>I am currently developing a map where the shortest route between two points is shown (using different transports). I have noticed that sometimes, roads that are for example closed in the winter, are not taken into consideration.</p>
  
  <p>I have found that I can ignore highways, tolls and ferries using the directionsservice (code below), but I can't for the life of me figure out how/if I can ignore seasonal restrictions. Any help is greatly appreciated.</p>
  
  <pre><code>var request = {
      origin: _marker_from,
      destination: _marker_to,    
      travelMode: _mode,
      avoidFerries: false,
      avoidTolls: false,
      //avoidTimedConditions: true &lt;-- I would need something like this
  };
  
  _service.route(request, function (response, status) {
      //More code here, not relevant for this question
  }
  </code></pre>
