Re: [sumo-user] query in gap based actuated traffic signal control

The warnings "has no controlling detector" indicate that actuation is not active at that intersection. This would also be the reason why different parameters do not affect the outputs.
The most likely reason for that warning are unprotected left turns without dedicated turning lanes. Please post a network that contains just the intersection controlled by traffic light n2.

hi all, 
i tried with gap-based actuated traffic control .  i want to know whether  the Max-gap value will affect the summary or trip output.  for a four leg straight cross intersection,   flow is set to 500v/hr.  i changed max-gap value to 2, 4, 5, 9. but there is no difference in summary or trip output. is it possible to get a difference.?
   my another query is 
when simulating with default actuated phase plan there is no warning.  default phase plan is 
<tlLogic id="n2" type="actuated" programID="0" offset="0">
<param key="max-gap" value="3.0"/>
  <param key="detector-gap" value="2.0"/>
  <param key="show-detectors" value="true"/>
  <param key="file" value="NULL"/>
  <param key="freq" value="300"/>
        <phase duration="39" state="GggrrrGggrrr" minDur="15" maxDur="50"/>
        <phase duration="6"  state="yyyrrryyyrrr"/>
        <phase duration="39" state="rrrGggrrrGgg" minDur="15" maxDur="50"/>
        <phase duration="6"  state="rrryyyrrryyy"/>
    </tlLogic>

if i change this phase plan  as below


<additional>
<tlLogic id="n2" type="actuated" programID="1" offset="0">
<param key="max-gap" value="9.0"/>
  <param key="detector-gap" value="2.0"/>
  <param key="show-detectors" value="true"/>
  <param key="file" value="NULL"/>
  <param key="freq" value="300"/>
        <phase duration="45" state="rgrGrgrgrGrg" minDur="15" maxDur="50"/>
        <phase duration="5"  state="ryryryryryry"/>
        <phase duration="35" state="GrgrgrGrgrgr" minDur="15" maxDur="50"/>
        <phase duration="5"  state="yryryryryryr"/>
    </tlLogic>
</additional> 
i get some warning

 is it ok to proceed or we need to rectify it.  how to rectify .


with thanks and regards
