What is defined as the part of a roadway where two or more roadways meet, measured from curbs or roadway edges?

The correct answer is the definition of an "intersection." An intersection refers to the area where two or more roadways converge, which is typically demarcated by curbs or the edges of the roadway. This convergence is critical as it is a common area where vehicles and pedestrians interact, and it requires specific rules and precautions for both drivers and pedestrians to ensure safety.

The term "crosswalk" specifically refers to designated areas for pedestrians to cross roadways, often marked by lines or signals; it does not encompass the full area where roadways meet. "Merge area" is a term used to describe sections of the roadway where vehicles are moving from one lane into another, primarily for merging onto highways and does not apply to the intersection setup. Lastly, "lane" refers to a specific part of the roadway designated for a single line of traffic, which does not capture the concept of multiple roadways meeting. Hence, intersection is the precise term defining the area described in the question.
