Purpose of Traffic Signs
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 motor vehicles, bicycles, pedestrians, equestrians, and other travelers.
Traffic signs are essential in providing road users with the information that they need to navigate the road system safely and efficiently.
Traffic signs, like any other traffic control devices, must meet five fundamental requirements:
- Fulfill a need
- Command attention
- Convey a clear, simple meaning
- Command respect from travelers
- Give adequate time for proper 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 traffic control devices, may breed disrespect for all signs in the area, and are often a waste of valuable public agency and taxpayers’ resources.
We break Traffic signs into 5 different categories:
- Regulatory Signs
- Warning Signs
- Parking Signs
- Construction Signs
- Security Signs
Traffic signs should be placed as necessary for safety and proper regulation of traffic. However, the use of too many signs in a given location may reduce the effectiveness of all the signs at that location.
