Hi everyone,

I'm trying to research about whether traffic lights in OSM, in dual-carriaged 
intersections, should be mapped on the intersecting nodes versus on the way 
where vehicles are supposed to stop. And I'm coming here to get a sense of 
OSRM's ability to handle this and traffic lights in general.

Here are two examples I'm looking at:

  lights on nodes:  https://www.openstreetmap.org/#map=19/35.13084/-106.58631
  lights off nodes: https://www.openstreetmap.org/#map=19/31.76873/-106.31877

I tried reading back through the mailing list archives here:

   https://lists.openstreetmap.org/pipermail/osrm-talk/

but I didn't see anything recently mentioned about traffic lights. The only 
documentation I saw on OSRM's homepage (http://project-osrm.org) was the API 
document (http://project-osrm.org/docs/v5.22.0/api/)

Does OSRM treat traffic light with weights? In the case where traffic lights 
are mapped on the  intersecting nodes where the ways cross, and a user wants to 
make a left turn through such an intersection, a potential route would mean 
crossing through three lights in a row. Would that be treated as three lights 
weighted enough for the router to find a way around it or treated as a singular 
cluster of one weight?

Thank you in advance for helping me understand.
