The modal hierarchy is retained at the Arterial base order rather than reassigned, a deliberate choice that signals the conflict between the pattern's real-world speeding effect and its nominal priority order, rather than papering over it with a different hierarchy.
Discouraged status here does not mean the pattern is banned; it means adopting it requires weighing the speeding tendency against whatever benefit, often traffic flow or signal progression, motivated the one-way conversion in the first place.
Default (No Parking, No Direct Property Access) (ART-DEF-01) (the two-way form this page's own citation, Riggs and Gilderbloom's evidence-based research on two-way conversion's livability gains, supports converting to, rather than the base order this pattern deliberately retains without reassigning)
