Hello, since you are using a custom algorithm for switching traffic lights, I cannot reproduce the problem by only using your provided net.xml and rou.xml file. If you can recreate the problematic situation using only a fixed plan I will take a look (you might try to create a (very long) fixed plan with all the phases that your algorithm selects in order). regards, Jakob
