A nice feature of this service is the ability to generate 'isochrones' - a visual display of how far you can travel from an origin within different time-duration bounds. http://maps.openrouteservice.org/reach?n1=8.992583&n2=-79.600754&n3=11&a=8.998822,-79.602424&b=1f&i=0&j1=90&j2=15&k1=en-US&k2=km http://maps.openrouteservice.org/reach?n1=8.992583&n2=-79.60...

I tried this for Lisbon, Portugal, and found it completely ignores one of the two bridges [0]. So it makes we wonder how good this service is.

  Could it be because three bridge is closed for cyclists? Seems to be working when you create it for cars. Either way it's probably a data issue and can be fixed if needed.

    My stupidity indeed. Thanks for pointinng this out. I assumed cars was the default (I changed the Panama link above). Both bridges are closed for cyclists, but ferries cross the river as well. So the routing includes those, very nice!

      I should have mentioned the bicycle setting in my link; Panama and the canal seem like a good example to illustrate how the shape of isochrones can change based on geographic and transport conditions (most cities will probably result in fairly concentric circles for walking, cycling and driving). Anyway, glad to hear that the routing takes those road usage restrictions into consideration :)

Nice, would be awesome if it could factor in traffic information.

  That would be great. It looks like the graphhopper project (another OpenStreetMap-based routing service) have done some research there: https://github.com/graphhopper/open-traffic-collection https://github.com/graphhopper/open-traffic-collection

I wanted to implement this myself a long time ago to e.g. show areas where the next school is at most x minutes away and the next public transit stop is y minutes away, but got distracted with other things... In this map you will have to find and select the amenities yourself but the functionality is mostly there. What I would really like to see though is a pedestrian + public transit mode... But I realize that this is hard ;)
