June McCarroll (June 30, 1867 – March 30, 1954) is credited by the California Department of Transportation with the idea of delineating highways with a painted line to separate lanes of highway traffic, although this claim is disputed by the Federal Highway Administration [1] and the Michigan Department of Transportation [2] as two Michigan men painted centerlines before her.

Painted lines tended to become invisible during rain. The initial dots were made of glass [6] and were attached to the road by nails or tacks, as suggested by Botts. [7] The nails were soon abandoned: his team discovered that when the dots popped loose under stress, the nails punctured tires.
The company (based in Ennis, Texas) changed its name to Ennis Traffic Safety Solutions and now markets the Stimsonite product line and descendants under the Stimsonite brand. Other manufacturers of retroreflective raised pavement markers sold in the United States under various designs include 3M , Apex Universal, Vialume, and Ray-O-Lite.
The North Luzon Expressway's raised plastic transverse rumble strips approaching Balintawak Toll Barrier, Philippines. Rumble strips (also known as sleeper lines or alert strips) are a traffic calming feature to alert inattentive drivers of potential danger, by causing a tactile fuzzy vibration and audible rumbling transmitted through the wheels into the vehicle interior.
A line drawn along the side of the road: White line: parking and stopping is allowed, but it isn't allowed on motorways and expressways. Yellow dash line: stopping is allowed, but no parking. However, some local governments allow parking at particular times. The time available for parking is written on a sign.
Graphs of maps, especially those of one variable such as the logistic map, are key to understanding the behavior of the map. One of the uses of graphs is to illustrate fixed points, called points. Draw a line y = x (a 45° line) on the graph of the map. If there is a point where this 45° line intersects with the graph, that point is a fixed point.

It illustrates why straight-line maps are more useful when only the sequence of stops is relevant. A straight-line diagram (abbreviated SLD) is a diagram of a road where the road is shown as a straight line. Such diagrams are usually produced by a highway department, and display features along the road, including bridges and intersecting roads.
