setting <tlLogic id="..." offset="-10"/> has the effect of making the whole cycle switch 10s earlier. The same effect can be achieved via TraCI using the following calls once at the start of the simulation:
remainingSeconds = traci.trafficlight.getNextSwitch(tlsID) - traci.simulation.getTime() traci.trafficlight.setPhaseDuration(tlsID, remainingSeconds - 10) (this assumes that the first phase has a duration of at least 10s) Am Mo., 25.
