A proven method to minimise the number of stops at traffic lights is a good coordination of the traffic. The use of vehicle-to-infrastructure (V2X) communication allows new concepts to achieve a better coordination. The here described system comprises both the adaption of the traffic signal control and the improvement of a vehicle's approach to intersections. Both objectives require accurate data concerning the actual traffic state and in particular the current tailback length. Therefore two data sources are used to estimate the current tailback length. Existing detectors at traffic lights are taken as a basis for the estimation. For an enhancement V2X data is used. Equipped vehicles send their current position and speed and thus operate as virtual detectors. In a further step detector counts and the V2X data are merged. The process tested in simulations was implemented within a test site in Braunschweig, Germany.
