Traffic Signs Of Road

Traffic signs or road signs are signs erected at the side of or above roads to grant instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, as an example, the fingerposts within the UK and their wooden counterparts in Saxony.

With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to beat language barriers, and enhance traffic safety. Such pictorial signs use symbols in situ of words and are usually supported by international protocols. Such signs were first developed in Europe, and are adopted by most countries to varying degrees.

Traffic signs are devices placed along, beside, or above a highway, roadway, pathway, or other route to guide, warn, and regulate the flow of traffic, including motorized vehicles, bicycles, pedestrians, equestrians, and other travelers.

Signs, like every other control devices, must meet five fundamental requirements:

-Fulfill a necessity.
-Command attention.
-Convey a transparent, simple meaning.
-Command respect from travelers.
-Give adequate time for correct response.

Signs should be placed only where warranted by facts and engineering studies. Signs that are unwarranted or ineffective may distract road users from more important control devices may breed disrespect for all signs within the area and are often a waste of valuable public agency and taxpayers' resources.

Signs should be placed as necessary for safety and proper regulation of traffic. However, the utilization of too many signs in a very given location may reduce the effectiveness of all the signs at that location.

Traffic signs are classified as:
-Regulatory signs.
-Warning signs.
-Guide signs.
-Regulatory signs give notice.
