Traffic signs setting out lane arrangements provide important and useful information for drivers, even when the road signs painted on the road surface are not visible for some reason. Though automatic traffic sign recognition systems are gaining real momentum and recent high-end cars are equipped with such systems, lane info traffic signs are often neglected by these systems. It is because of the high variability of the lane arrangements and their arrow-based representations. Herein, a syntactic approach is presented to describe lane info traffic signs and to decode and recognize their message in an automatic manner. The morphological features used for the purpose are kept intentionally simple at this stage of the research
