Hi José,

the string "state" contains the state for all links the are controlled by this traffic light. Each char sets the state for a link (or multiple links with the same index).

For the meaning of the chars, see:

http://www.sumo.dlr.de/daily/pydoc/traci._trafficlight.html#TrafficLightDomain-setRedYellowGreenState

"Sets the named tl's state as a tuple of light definitions from rugGyYuoO, for red, red-yellow, green, yellow, off, where lower case letters mean that the stream has to decelerate."

Duration is the duration of a phase in seconds, meaning the time the traffic light will remain in the given phase before moving to the next one. In the example program, you can thus see, for example, links 0 and 1 will remain green for 31 seconds, then yellow for 5 seconds, then red for the rest of a cycle.

Hope this helps,

Greets,

Menno

Dear all,

Regarding to traffic lights, I was reading the wiki, and I saw the following example of TLS program,

<additional>
    <tlLogic id="0" programID="my_program" offset="0" type="static">
       <phase duration="31" state="GGggrrrrGGggrrrr"/>
       <phase duration="5"  state="yyggrrrryyggrrrr"/>
       <phase duration="6"  state="rrGGrrrrrrGGrrrr"/>
       <phase duration="5"  state="rryyrrrrrryyrrrr"/>
       <phase duration="31" state="rrrrGGggrrrrGGgg"/>
       <phase duration="5"  state="rrrryyggrrrryygg"/>
       <phase duration="6"  state="rrrrrrGGrrrrrrGG"/>
       <phase duration="5"  state="rrrrrryyrrrrrryy"/>
    </tlLogic>
</additional>


From each of the phases, how can I read what it means the state and the duration?
How can I tell from that example the time spent for red, yellow and green?


Best regards,
José
