Tool for Generating Isochrones: Mapzen Mobility Explorer
Via Steve Vance, Mapzen has a new tool, Mobility Explorer, which can generate isochrones for walking, biking, driving, and transit. I have previously used tools provided by Walk Score, but Mapzen seems more accurate, and the transit shed can be calculated based on a time-of-day.
The colors on the web site color scheme are not that great. On Steve’s blog you can see he’s generated his own map via an API call.
