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:

In the past blog post I wrote about the newest changes and encoding techniques that have been implemented in the Open Source Routing Project (OSRM). So I think it is time do a little comparison analysis about the request/response time of several routing APIs. The main question I wanted to answer was: “Is an OpenStreetMap direction service faster than G**gle?” I tested the following direction APIs for cars (fastest): MapQuest, CloudMade, G**gle and finally OSRM. For the analyses I wrote a small Java tool, which measured the time to get a result of a routing-service. I did all tests at home with a “regular” 12kbit/s internet connection. I tested several distance levels and the results can be seen in the following table. It shows the average times of five requests for each route with a delay of 3 seconds between each request/response. Overall I did this analysis three times.
