[OSRM-talk] map matching service for a huge number of requests

[Sayer, Bryan]

We use the Stata implementation OSRMTIME from Stephan Huber at Regensburg University  which can split the data across threads (we have 2 CPUS with four cores each, and two threads per core). So 16 threads on a 3.5 Ghz Xeon and 64 GB of RAM, and if the network traffic is low (like on holidays) I can get about 1.2 million routes per hour in the United States.


Of course, this requires having Stata, but we find it is a pretty good way to do batch routing. I recently did about 460 million routes. But it only returns distance and time, not the actual route, if that matters.

Subject: [OSRM-talk] map matching service for a huge number of requests

Hi,
I want to call the map matching service for nearly a million of routes. I calculated that the task could take 10 hours on my laptop to complete. I was wondering if there's someone who faced the same problem and who addressed it in parallel, maybe with Spark? Another tool or way?
Any hint is greatly appreciated!
Patrick
