Maybe some of you remember that I conducted a comparison analysis between three OpenStreetMap (OSM) routing engine APIs (CloudMade, MapQuest Open and OSRM) and G**gle Maps API last week. You can find the results in my blog post here. As I mentioned in the article, I wanted to try to do a second analysis with more routing engines.

Thus, I added Bing Maps and two OSM engines (YourNavigation/YOURS and Routino/Roadeeno) to the comparison. All services have a continental coverage with the exception of OSRM. The following table shows an overview of (1) the request-response time of the service, (2) the calculated distance for the test-route and (3) the file size of the service response:

As you can see in the following diagram does the OSM routing engine (OSRM) give the fastest results. A little bit strange is that the Routino/Roadeeno service returns no valid route responses for requests which are longer than 600 km.

The same diagram in a more detailed view:

First of all, sorry that I did not create a new stat regarding the Routing View past month. To all the new readers: Usually I create an analysis about the Routing View of the OpenStreetMap Inspector for each month for Europe. You can find more information about the OSM Inspector (OSMI) here. The Routing View within the OSMI “shows problems in the data related to routing and navigation”. You can read more about it here … A direkt link to the OSMI Routing View is here!

However, here are the new stats for May, 2011: we have a total of about 124000 “Unconnected Roads” and about 108000 “Duplicate Ways” (number of duplicate segments). Overall this means that we have about 17000 *new* „Unconnected Roads” errors and only ca. 1300 “Duplicate Ways” have been fixed in Europe. For the past three months we have an increment of about 2850000 new OSM way segments for routing. (May 7th: 34500000, February 20th: 31700000, January 20th: 30600000)
