First, thanks for answering fast. But this component sigma, I've already looked for it before, and my code is:
*<vType id="carro_10" accel="2.6" decel="4" length="3.0" maxSpeed="24" sigma="0"/><route id="rota10" edges="gneE9 gneE15 gneE16 gneE17 gneE85 gneE86"/>* *<vehicle departSpeed="max" depart="0" id="veiculo_10" route="rota10" type="carro_10"/>* For both simulation, with and without SpeedSign, the route file is the same, I have not changed. Can be this the cause of the difference in the time ?
