street signs, signage
Nighttime driving carries a higher risk of collision than daytime driving due to lack of sunlight. While most highways and roads are illuminated with street lamps, they don't provide the same level of lighting as the sun. Because of this, roughly half of all collisions occur at night, even though only 75% of travel happens during the day. To help reduce the risk of nighttime collisions, the Federal Highway Administration (FHWA) requires developers and contractors to use traffic and street signs with a minimum amount of retroreflectivity.
Retroreflectivity is defined as the reflection of light off a given surface. When a car's headlights strike a retroreflective-coated sign, the sign will bounce back some of that light to the car. This allows drivers to see signs more easily at night and, therefore, lowers the risk of collision. The FHWA has used reflective properties in road and street sign specifications for more than a half-century. It wasn't until the 1990s, however, when the organization updated its Manual on Uniform Traffic Control Devices (MUTCD) to require a specific level of retroreflectivity for road and street signs.
Types of Retroreflective Sheeting
As revealed on the official FHWA website, there are several types of retroreflective sheeting, including the following:
How to Maintain Retroreflectivity
It's important to note that a sign's retroreflectivity may decrease over time, which is why the FHWA requires communities to maintain a minimum level of retroreflectivity with their road and street signs. The FHWA supports several different testing methods to maintain the retroreflectivity of signs. Communities can either perform a nighttime visual inspection of their signs, measure precise retroreflectivity levels using a retroreflectometer, check their signs' expected life or simply replace their signs.
