What do collectors involve in terms of road function?

Collectors serve a crucial role in road function by providing both land access and facilitating traffic circulation within urban and suburban areas. These roads are designed to gather traffic from local streets and direct it to arterial roads, which handle higher volumes and higher-speed travel. By connecting residential, commercial, and other land uses, collectors enable easier access to various destinations while also managing the flow of traffic to ensure smooth circulation. This balance of access and mobility is essential for maintaining efficient transportation networks, allowing for movement within communities without overwhelming the higher-capacity arterial roads.

In contrast, the other options pertain to different road functions that do not align with the primary purpose of collectors. High-speed transit is more aligned with highways and expressways, which prioritize quick movement over access. Commercial access emphasizes the service of businesses and may not encompass the broader traffic circulation function of collectors. Inter-city connections highlight long-distance travel routes that are beyond the scope of collector roads, which primarily serve local areas rather than connecting cities.
