Abstract
We examine the network performance of algorithms for self-organized traffic management with a strong focus on the wireless networking between the cars. One of many technologies to make road traffic more safe and efficient is the Virtual Traffic Light (VTL) system which is able to coordinate traffic flow at intersections without the need for physical lights. VTL uses a leading vehicle at the intersection for controlling the traffic light. We developed algorithms for leader election and traffic light computation in realistic vehicular networking scenarios. Our key contribution is the extension of this algorithm to support arbitrary intersection layouts. We investigated the proposal in synthetic and realistic scenarios. Our results show that, overall, VTL uses network resources efficiently and has a positive influence on the driving experience and outperforms stationary traffic lights at low to medium network load. We further identified optimization potentials in dealing with high network load and fairness.
