3M has provided some of the leading traffic safety solutions around the world. Retroreflective technology is one of them, and was pioneered for development by 3M some 80 years ago. As the technology advanced over the years, international as well as Indian road safety standards for urban, rural and highway roads have also changed to embrace these improved technologies.
From replicating the light-reflecting qualities of the eyes of animals in the early 1900s, to today’s highly retroreflective full cube technology, the route to improving road sign visibility for better road safety has come a long way.
Technological advancements have produced increments in light return efficiency. It has risen from around 8% of returned light (1930s) to 16% (1970s), and then to 32% (1990s) and to the current high of 58% with 3M full cube technology.
The quality of the product and ease of installation makes 3M road safety products well-rounded solutions for road safety. See the unique product features that are designed to help make a difference to the work of road safety engineers, and road construction workers.
