Highway infrastructure often features a variety of signboards, each serving a crucial role in guiding motorists safely to their destinations. Among these, green-colored signboards play a significant role, providing essential information and ensuring uniformity in road signage. In India, green boards are predominantly used on highways, although blue signboards are also observed in certain regions. The choice of green for highway signage is not arbitrary; rather, it stems from standardised practices aimed at enhancing visibility and clarity for drivers nationwide.
Standardisation and Visibility
The primary reason behind the adoption of green for highway signboards is standardisation. This colour has been selected to ensure consistency and ease of recognition across different regions and terrains. According to experts, green is particularly effective in blending with the natural surroundings while remaining conspicuous enough to catch the attention of drivers.
Functional and Symbolic Importance
Green signboards serve multiple functions, from providing directions and distances to highlighting landmarks and service facilities. This colour choice is also rooted in cultural symbolism, as green traditionally signifies security, growth, and environmental responsibility in Indian culture. By associating green with road safety, authorities aim to foster a positive attitude towards responsible driving practices among motorists.
Research and Practical Application
Research conducted by transportation departments, such as the Arizona Department of Transportation, has affirmed that green is a non-distracting colour that integrates well into the driving environment. This aspect further underscores its suitability for highway signage, where clarity and minimal distraction are paramount.
Conclusion
In conclusion, the installation of green-coloured signboards on highways serves a dual purpose: enhancing road safety through clear and standardized information dissemination and fostering a positive cultural association with responsible driving practices. By choosing green, authorities ensure that motorists can navigate roads more effectively while promoting environmental awareness and safety consciousness.
