Final answer:
The correct color line markings on a one-way street are a solid or broken white line, which helps control and guide traffic in city environments.
Step-by-step explanation:
The color line markings found on a one-way street are typically a solid or broken white line. These are designed to indicate traffic flowing in one direction.
Examples of different line markings include a line of one foot, which is a standard measure for broken lines, and a line of two feet, which may be used for longer dashes in certain road marking applications.
On roadways, these white lines help control traffic and guide drivers effectively through two-dimensional, zigzagged paths in cities, as depicted in Figure 3.2, illustrating traffic patterns in cities such as New York.
