Reflectors in traffic engineering
We encounter reflectors in many different ways in our daily lives, including in the important traffic engineering sector. Retroreflectors are safety devices which, particularly in the dark, reflect incident light back to the light source. The special optical, chemical and mechanical properties of glass ensure that this material finds many uses in the challenging traffic engineering sector. Its hardness and heat resistance are enough to ensure that it is often preferred to plastics.
