Which type of road provides the lowest capacity and direct access to building sites?

Local streets are designed primarily for direct access to residential and commercial properties. They serve lower volumes of traffic compared to other road types and facilitate circulation within neighborhoods or smaller areas, making them ideal for providing direct access to building sites. Due to their lower design speeds and capacity, local streets typically allow for a more intimate environment, accommodating pedestrians and cyclists alongside vehicles.

This function contrasts with collector streets, which are designed to gather traffic from local streets and funnel it to arterial roads while managing moderate traffic volumes. Arterial streets are built for higher traffic capacity and longer-distance travel, while expressways are designed for high-speed, high-capacity movement of vehicles with limited access points, thus providing minimal direct access to adjoining properties. Local streets stand out as the road type that caters specifically to direct access and has the lowest capacity.
