What is the primary function of a collector street?

The primary function of a collector street is to connect local streets with arterial streets. This type of street plays a crucial role in the overall street hierarchy and transportation network by facilitating the movement of traffic from residential areas to larger, higher-capacity roads. Collector streets are designed to adequately handle moderate traffic volumes while providing access to properties along their routes. By connecting local streets, which typically serve single-family homes or small neighborhoods, to arterial streets that support heavier traffic flow, collector streets ensure an efficient transition for vehicles traveling between lower-density areas and major thoroughfares. This function is key in urban planning as it balances access and mobility, helping to efficiently direct traffic where it needs to go while maintaining safety and accessibility for residents.
