Abstract
Merging lanes on a motorway often form a serious bottleneck. Not only because capacity decreases downstream of the merging location, but also as the result of non-optimal merging behavior of the drivers. The competitive merging environment furthermore easily leads to unsafe conditions. By guiding the drivers with moving light signals embedded in the motorway road surface, the merging capacity can be increased significantly. The guiding algorithms together with the surrounding infrastructure, such as variable road markings, can be optimized for traffic safety. For the covering abstract see ITRD E209471.
