OTv1 overview
The nature of this project (crowd-sourced, collaborative, big data, geospatial, append-only) leads me to think of using a distributed architecture, a bit like how DVCS works. A distributed architecture could...
As discussed with @abyrd we can self-validate the traffic model (+routing) by comparing observed O/D travel times against estimated travel times using the traffic model. By sampling O/Ds from within...
As stated in the architecture README: The Traffic Engine (TE) translates vehicle location to OSM-linked speed estimates. By design the TE can be run inside a fleet operator allowing internal...
For some ways the speed profile (at least before an intersection) depends a lot on the direction taken at the following intersection. For example, a left turn being on average...
[Announcing the GPX Planet](https://blog.openstreetmap.org/2013/04/12/bulk-gpx-track-data/). 2.6 Trillion GPX points. It could be nice to be able to use this (or part of it) as a GPS source.
Can we develop a stats bucket that grows the time window to capture data in a reasonable way?
How does TrafficView fit into the picture here? https://www.trafficview.org/partners/
Can we load planet.pbf into the system? is that the right way to run multiple cities?
need to know per thread, per core, and per machine throughput need to know per vehicle memory overhead and make sure we don't leak
