Final answer:
The subject of this question is Geography. It relates to roadways with low traffic volume and varying speeds, which can be categorized as local or secondary roads in transportation and infrastructure.
Step-by-step explanation:
Specifically, the question is referring to roadways that carry a low volume of traffic and can have varying speeds. In geography, this concept can be related to transportation and infrastructure, specifically in regards to the classification and design of roads.
In terms of transportation, roadways with low traffic volume and varying speeds can be categorized as local or secondary roads. These types of roads typically connect small towns or rural areas and may have less traffic compared to major highways or freeways. Local roads may not have strict speed limits and can vary depending on the road conditions and surrounding environment.
For example, in a rural area with hilly terrain, a local road might wind around mountains and have a lower speed limit due to the challenging road conditions. On the other hand, in a suburban neighborhood with low traffic, local roads may have relatively higher speed limits compared to urban streets.
