If drivers were asked, they would probably say that traffic lights and road signs give them the information they need to drive safely and obey the laws. Most drivers take the traffic markings on the road for granted. They are so used to these subtle signs, they don't always appreciate how important they are. Officials make decisions all the time regarding the pavement marking AR drivers see.
The Department of Transportation in every state has to decide how to apply markers to the roadways. They take into account the traffic count, function and location, climate, availability of equipment, labor force, cost versus life span, type of paving materials, and how much money they have to work with. All of these factors come into play when the various authorities set out their budgets every year.
Paint was the first material ever used to mark the roadways for drivers. Today paint is still the most popular and widely used material. Of the four base materials used in its manufacture, three are solvent borne, and one is water borne. The solvent borne are the most common, but because it is more environmentally friendly, the water borne paint is being applied more often than in the past.
Thermoplastic has been used since before the Second World War and is preferred by many because they do not contain solvents, which makes them more environmentally friendly. They also have the advantage of being more visible under rainy night conditions and have a longer life span than paint in warm climates. Thermoplastics are not as long lasting in cold climates however. They do require surface preparation, in the form of primer or some other treatment, in order to maximize the adhesion.
Thermoplastics and paint do not have the ability to reflect in their natural states. Without the addition of some reflective element driving at night and during bad weather can be risky. At the present time, glass beads are the preferred method to create reflection on the roadways. Their shape and transparency makes them naturally reflective.
Tape is often put down as a temporary marker to direct traffic while roads are under construction or being repaired. It is becoming more commonly used as permanent markings. The initial cost is higher than paint or thermoplastic, but it is easy to repair if it tears or comes loose. Tape comes from the factory in big rolls and is usually applied to the pavement with the use of an adhesive.
Raised markers are often hated by drivers who try to go over them too quickly, even when they have had advance warning about them. These markers, or buttons, are extremely effective at getting drivers' attention. They have the added advantage of being raised above the pavement, which makes them easy to see when it is raining.
The Department of Transportation makes every effort to keep drivers safe. It provides clear instructions in the form of roadway markings, signs, cones, and warning lights. It is up to drivers to pay attention to them.
