Abstract:
The strong and, in part, further increasing traffic volumes of individual and heavy goods traffic in urban regions lead to a utilisation of the networks close to or above the capacity limit, especially during rush hours. Traffic light control is ideally traffic-dependent, which can be realised either centralised or distributed as a self-organised approach. However, these systems are typically not able to detect disruptions or incidents (such as accidents, road works, etc.) and take them into account in the control logic. A key problem here is that either there is no incident detection in place or it is not reliable enough. In this paper, we discuss the need for collaborative validation of locally detected incidents in a self-organised traffic control system. We show that this can increase the reliability of detection to the point where incident-dependent switching becomes possible.
