[sumo-user] Problem with Traci changetrafficlight

[<Rob...@pe...>]

Hi all,

I have a problem with the following traci command:
TraCI/Change Traffic Lights State
Command 0xc2: Change Traffic Lights State (ubyte Variable, string
TrafficLightsID, ubyte ValueType, ValueType Value)
state (light/priority tuple) (0x20)

I send the following:
0 0 0 35 31 -62 32 0 0 0 3 120 112 50 12 0 0 0 16 114 114 71 71 71 71 71 71
114 114 71 71 71 71 71 71
71 is "G" in ASCII and 114 is "r".

When I send a capital "G" cars are still braking in front of the green
traffic light, while in the case of a SUMO controller with a capital G in
the fixed time program (so not using traci) the cars don't brake. Is it
possible that somehow internally in SUMO the case is ignored or am I doing
something wrong?

I can send the java program and the network file I'm using if you want to
try it out, but I'm not sending right now because the mailing list will
probably block the attachment.

Thanks,
