The authors were able to successfully fake a continuous flow of bicyclists to turn the cyclist traffic light instantly green or decrease the time to green. This hack could be performed from any remote location, allowing someone to remotely influence traffic at scale. The regular security systems that prevent lights from turning green simultaneously were not affected.
