I'm trying to update the driving way speed limits in OTP. I have seen how opentraffic data graph updater does it, and I have created a custom one that reads from a very simple Json (just the 4 mandatory fields, wayId, startNodeId, endNodeId and average traffic speed ).
I have access to road devices that calculate the average speed in a given point which, in order to give it to OTP, I need to associate with a way, start node and end nodes ids.
To do that I have tried using QGis to load the OSM file data, now I can select the way, and know the wayId. But how can I view its nodes? Is there a simpler way to do this?
