Commercial Arterial
ART-CAR-07 Commercial Arterial
Typical at: Suburban Compact Urban
#Why this pattern exists
(Documented anti-pattern) This is one of the most common current commercial-corridor patterns in the US (the typical suburban commercial-strip arterial), and it violates Commonway System’s core Arterial design principle that arterials should carry through-traffic without direct property access or on-street parking, the same principle that defines a Stroad. Documenting it as an anti-pattern gives it a name and a citation-backed explanation, paired with a route to the correct alternative treatment.
#Key considerations
- Every direct commercial driveway onto the arterial is a conflict point that undermines both through-traffic flow and safety
- The correct alternative is a Frontage/Service Road pattern parallel to the arterial, aggregating access points before they reach the arterial itself
- Closely related to, but distinct from, Stroad: a Commercial Arterial may not necessarily include on-street parking, but shares the same core access-management failure
#Related patterns
Stroad (ART-STD-05) (closely related anti-pattern), Frontage/Service Road (LOC-FSR-04) (the correct alternative), default Arterial pattern (ART-DEF-01) (the no-direct-access principle this pattern violates)
