Traffic jams and travel delays are a large problem still plaguing road users in the Netherlands. It is estimated that the yearly costs associated with this can go as high as 1.8 billion Euro’s on an annual basis.


One solution is to expand the infrastructure, but this is not always possible, desirable or effective. There are situations where the infrastructure has not reached its theoretical throughput limit, but experiences frequent traffic jams anyway. Unbalanced lane use, situations where one lane is much busier than neighbouring lanes, can be a cause. Unbalanced lane use reduces the capacity of motorways to absorb disturbances: a single lane change can trigger the onset of congestion in one of the lanes, which then spreads to the other lanes.


Solving this problem will require active traffic control on the lane-level. We will need to be able to detect situations of unbalanced lane use and determine the best way to solve them, be able to request changes of lane for individual drivers and be able to identify the exact lane on which a given car is driving so that the appropriate requests can be formulated.
