What type of road serves as a main feeder street providing access while signaling where needed?

The correct choice is a collector street. Collector streets are vital in the street hierarchy as they serve to collect and distribute traffic from local streets to arterial roads. They function to provide access to neighborhoods, commercial areas, and other significant destinations while also facilitating the movement of traffic.

Collector streets are designed to support moderate traffic volumes and speeds, effectively bridging the gap between local streets, which primarily serve residential areas, and arterial roads, which carry larger volumes of traffic over longer distances. They often have lower speed limits compared to arterial roads and provide safe transitions for vehicles entering and leaving local streets.

In contrast, secondary arterials also play a role in traffic distribution but are more focused on connecting larger areas or regions rather than specifically servicing neighborhood access. Local streets prioritize residential access and may not accommodate through traffic efficiently. The term "zoning" relates to land use regulations rather than roadway functions, making it irrelevant to the question of road types.
