Re: [sumo-user] tlLogic phases
TLC with long green duration performs better in high traffic due to the time "wasted" at every switch.
TLC with short green duration performs better in low traffic because each arm is served more frequently.

Dear sumo users,

My question is not related directly to SUMO simulator but to traffic light
system.
I need to know the number of phases for the traditional TLC of 30s and for
10s for intersection of 4 roads, 2 directions in each road, and 3 lanes in
each road, the intersection include crossing also .

I tried with this code (depending on my guess)  for 30s TLC:
<tlLogic id="0" programID="my_program" offset="0" type="static">
      <phase duration="30" state="rrrGGGrrrGGGGrGr"/>
      <phase duration="5"   state="rrryyyrrryyyrrrr"/>
      <phase duration="30" state="GGGrrrGGGrrrrGrG"/>
      <phase duration="5"   state="yyyrrryyyrrrrrrr"/>
   </tlLogic>

And this code for 10 s:
<tlLogic id="0" programID="my_program" offset="0" type="static">
      <phase duration="10" state="rrrGGGrrrGGGGrGr"/>
      <phase duration="5"   state="rrryyyrrryyyrrrr"/>
      <phase duration="10" state="GGGrrrGGGrrrrGrG"/>
      <phase duration="5"   state="yyyrrryyyrrrrrrr"/>
   </tlLogic>

When I get the results in term of trip duration and waiting time the 30s
system outperform the 10s system what is not logical. I think that my
phase's state and duration is wrong.

Please let me know if you have any idea about traditional TLC of 30 and 10
s, or any suggestion that would make my simulation more logical.
