Hi, Thank you very much for your feedback.
I'm using sumo.0.19.0 for now. I tested with 0.20.0 and it still occurs. I investigate a little more and find that with fixed cycle fixed time traffic light, it seems to be OK. However we are testing an algorithm to update traffic light time and even cycle online. And it is here that the problem occurs Please find in the attachement the net-file and route-file in google driver, it's big. https://drive.google.com/file/d/0B0RFzBhW5MOUVUFDa2VrbGpYRHc/edit?usp=sharing https://drive.google.com/file/d/0B0RFzBhW5MOUZ2NBenNuRmhZdlE/edit?usp=sharing https://drive.google.com/file/d/0B0RFzBhW5MOUeE4wNm1fa0NoSXc/edit?usp=sharing Tks again.
