The principal arterial system should carry the major portion of trips entering and leaving the urban area, as well as the majority of through movements desiring to bypass the central city. Almost all fully and partially controlled access facilities will be part of this functional system.
Minor Arterial Urban Trips of moderate length at a lower level of mobility than principal arterials. Some emphasis on land access. May carry local bus routes and provide intracommunity continuity but does not penetrate neighbourhoods. Rural Serve intracounty travel with travel distances shorter than on arterial system. More moderate speeds.
Other Principal Arterials and are rather evenly spaced. Note that only a few of these Minor Arterial routes actually extend outside of the city border, as most of them terminate at Arterials within the city limits. The Collector roadway system (shown in brown) consists of relatively shorter routes that mainly connect to Minor Arterials.
Arterial road - Wikipedia
An arterial road or arterial thoroughfare is a high-capacity urban road that sits below freeways/motorways on the road hierarchy in terms of traffic flow and speed. [1] [2] The primary function of an arterial road is to deliver traffic from collector roads to freeways or expressways, and between urban centres at the highest level of service ...
FHWA has seven functional classifications, interstate, other freeways and expressways, other principal arterial, minor arterial, major collector, minor collector and local. Each classification is based on the roadway’s function within the roadway system. FHWA sets requirements for the functional classifications.
