Avoids roads where bicycle access in OpenStreetMap is set to false
Avoids all limited access highways
Favors bike specific paths (road segments that have bicycle access only - no auto or pedestrian)
Favors walkways with no auto access
Applies various weights to roads based on the maxspeed tag (ex. favors routes where maxspeed <= 30 mph)
Continuing with the Open theme, bike routes can also be combined with the Open Elevation Service. Remember, it's still in Beta and we'd appreciate it if you can limit the routes to less than 200 miles. (I know, we apologize - you were looking forward to biking over 200 miles tomorrow, weren't you?)
Similar to all our other Open Services, no AppKey is necessary! What you will need, however, is a collection of lat/longs along its route to produce the elevation chart. Fortunately the above Open Directions request can provide the coordinates for us. With this info in hand, we can request Elevation with the following:
The elevation chart is heavily dependent on the generalize parameter for the Open Directions Service. As you might expect, the higher the generalization, the more simplified the elevation chart becomes. Check out the Developer's Guide to read more about the generalize parameter and shape simplifications under Advanced Routing Options and Parameters. And definitely stay tuned for more details regarding the Open Elevation Service!
