Traffic signs are one of the most important factors in creating security and prosperity in cities. Traffic signs reduce the likelihood of accidents and violations as guidance and monitoring tools, and assist traffic police in managing and controlling traffic with proper and appropriate reform. Therefore, improper, inadequate or unprincipled guidance signs will have the opposite effect.
Paying attention to and respecting traffic laws, as well as the optimal efficiency of traffic signs and equipment before it is a scientific and technical issue, is a cultural issue and naturally needs to be cultured.
In general, for traffic signs and signs used in cities, several general roles can be determined as follows:
Urban and road information boards
Urban and road signs and traffic signs
City signboards and signs
Identification signs (buildings, squares, alleys, parks, etc.)
Temporary signs such as showing construction operations, construction or repair, etc.
User introduction boards
Design of signs and information boards
Shape and form:
Many signs have international standard forms and it is not possible to apply tastes in them, such as: triangular signboards, rectangular and circular signs; Therefore, urban signs must be carefully designed and constructed to comply with global design standards and regulations. However, some signs that have a local-regional aspect are required to comply with their national or regional standards.
Signs with short and useful messages shorten the time it takes to receive a message, determine the user’s quick reaction, and are more appropriate in advancing traffic management goals.
According to the standards of different countries, the height of urban signs is slightly different. Regional laws can also vary, but most of these laws set the height below two-thirds of the height of the buildings. Billboards should be 2.5 to 3 meters above the sidewalk, and 4.5 to 4.7 meters above the street level.
Location and installation:
The placement of traffic signs and information boards is a very important issue in traffic control and information purposes. Therefore, according to the location and space of the environment and with regard to traffic standards, it should be done in a principled and accurate manner.
Material and fittings:
The raw materials used in the production and manufacture of traffic signs and signs must be resistant materials; Such as: iron sheets with paint or hot-dip galvanized coating, aluminum, etc. In addition, their foundation should be designed and executed from reinforced concrete and as a base plate. The type of shingles used in traffic signs and traffic signs greatly affects their lifespan.
