Traffic signboards provide important information, directions and warnings on the road; they are designed and placed as assistance to drivers. They keep traffic flowing freely by helping drivers reach their destinations and letting them know entry, exit, and turn points in advance. Pre-informed drivers will naturally avoid committing mistakes or taking abrupt turns and causing bottlenecks. Comprehension of traffic signboards is crucial to safety, but they are not always detected or recognized correctly. Signboards present issues in terms of detection and recognition due to poor visibility, bad weather conditions, the color combinations used, their height and position, vehicle speed, and driver’s age and vision.
