What to Look for in Urban Road Sign Recognition?

[McVictoria]

Urban road sign recognition generally refers to guide signs on ordinary roads. Guide signs for ordinary roads: Color and graphics: blue background with white graphics, white borders, and blue edging. Classified by function: route guidance signs, location guidance signs, roadside facility guidance signs, and other road information guidance signs. Principles for reading road signs: The general principles are: left for near, right for far; top for near, bottom for far. Route guidance signs are divided into: intersection advance signs, intersection notification signs, and confirmation signs. Intersection advance signs for ordinary roads are mainly used on highways. Due to the high density of urban road networks and short distances between intersections, such advance signs are rarely installed on urban roads. The layout and information selection for intersection notification signs are consistent with advance signs, with the only difference being that advance signs include distance information on the sign panel.
