Hi everyone,

I want to ask about traffic lights in dual-carriaged intersections. 
Sometimes the intersections have traffic_lights on the intersecting nodes 
where the ways cross, and sometimes the lights are outside of the 
intersecting nodes. Here are two examples of intersections and the 
different ways traffic_lights are placed:

  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 have been moving traffic lights out out of these intersections, largely 
for the reason brought up here:

  https://groups.google.com/forum/#!topic/osmand/jHjZ_zGF_Vg

I would see that if a user needs to make a left turn, through an 
intersection with lights on intersecting nodes, the router would penalize 
the path heavily for having to route through three traffic lights in a row. 
I have been told that if the intersection has lights in the intersecting 
nodes, that is sufficient for mapping and should not change. The OSM Wiki 
page seems to state that "there is no well established convention on how 
this problem should be ideally solved".

I am genuinely curious to know from OsmAnd developers what their point of 
view is. Does OsmAnd's routing prefer traffic_lights moved out of 
intersecting nodes of dual-carriaged intersections, or does its routing 
treat a cluster of traffic_light'd nodes as a single weight?                
         

Thank you in advance for helping me understand.   -curtis
