Cul-de-sac
STR-CDS-003 LocalCul-de-sac
Typical at: Suburban
Compact is an edge case. Undeveloped, Rural, Urban, and Core are unlikely pairings.
Caution
Cul-de-sac carries Situational status. The connectivity and walkability expectations that define Urban and Core density are close to incompatible with a dead-end street pattern, so this Typology's realistic range is narrow, peaking at Suburban.
#Modal hierarchy
Pedestrian, then Bicycle, then Vehicle, then Freight, the Local base order minus Transit, since a dead-end street rarely carries a transit route.
#Design notes
A cul-de-sac trades network connectivity for a quiet, low-through-traffic environment. That trade only holds up at lower densities, where a disconnected street grid does not yet conflict with pedestrian and bicycle route continuity.
