Correcting bicycle facilities on Google Maps
Friday, May 14th, 2010
Unless you’ve been living under a rock, you know Google has added bicycle directions to Google Maps.
And, when you’re looking at their map, you can turn on the bicycling information by hovering over the “More…” button. The bicycle facilities that show up (e.g. bike lanes, bike routes) are given priority when giving directions.
One problem is Google thinks there are bicycle facilities where they are none.
For example, you’ll see a dark green line show up on the east side of Woodward around 12 Mile Road (as of this morning or the attached picture.) It’s about 50 feet east of Woodward, roughly where parts of an alleyway exists — and that’s not something they should be routing us on.
After this showed up on some bicycle routing we made on Tuesday, we clicked on Google’s Report a Problem link. We selected the bad routing portion from the drop down menu and said, “There is no road or bicycle facility to turn on to.” We quickly received a confirmation email.
This morning we received this response:
Your Google Maps problem report has been reviewed, and you were right! We’ll update the map soon and email you when you can see the change.
In our opinion, less than three business days is a decent turnaround time for investigating this issue. We’ll see how soon they update their base map.
There are other non-existent or improper (e.g. sidewalk) bicycle facilities throughout this area. Clearly Google is relying on similar efforts from many people (i.e. crowdsourcing) to improve their bicycle routing.
