Activity 4: High Visibility Signs

Highway signage has evolved over time in response to driving habits and advances in automotive technology and materials science. Although most informational signs have a nondescript appearance, the microscopic structure of their surfaces is complex. Many competing designs attempt to provide advantages when illuminated by headlights. It is often true that designing a test to evaluate different items is as important and challenging as designing the items themselves. In this activity, students will design both highway signs and a reliable procedure for testing them.https://digitalcommons.imsa.edu/future_highway_theme2/1003/thumbnail.jp
