The vector stencils library "Road signs" contains 58 symbols of road signs for labeling the road and route maps, directional and transit maps, street and locator maps.
"Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users.
... many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees." [Traffic sign. Wikipedia]
The pictograms example "Road signs - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Directional Maps solution from the Maps area of ConceptDraw Solution Park.
